1. SUMMARY
Salmon escapement monitoring was conducted at four stations on the Susitna
River and one station on the Yentna River. These stations were operational
from late June to mid September, 1981. Methods used included side scan sonar
counters and fishwheels. Chinook salmon escapement surveys were effected in
late July and early August on tributary streams. A radio telemetry tagging
program monitored the migrational movements of adult chinook, chum and coho
salmon between late June and early September. The Susitna River mainstem was
surveyed for spawning activity by three crews from late July through September
using primarily drift gill nets, electroshocking equipment and egg deposition
pumps. Set netting was effected at river mile (RM) 150 in the Susitna River
mainstem immediately below Devil Canyon (RM 151) from late July to mid
September. Susitna River tributary streams and sloughs between the Talkeetna
River confluence (RM 99} and Devil Canyon were surveyed on foot for spawning
salmon from late July through September.
Fishwheel catch and sonar enumeration data indicate the chinook salmon
migration was underway before the fishwheels and sonar counters were placed.
Peak migration timing was determined at Sunshine (RM 80), Talkeetna (RM 103)
and Curry (RM 120) stations. Commencement of migration was recorded at only
Curry Station. A correlation may exist between river discharge and upstream
migration. The 1981 Susitna River chinook salmon escapement was dominated by
four year old fish. Length measurements segregated by age and sex indicate
that chinook salmon at Talkeetna and Curry stations were significantly larger
than those intercepted at Sunshine Station. Early smelting is a possible
E-1-1
cause based on a higher percentage of Talkeetna and Curry station fish having
spent less than one winter in freshwater before smolting. Radio telemetry
i nvesti gati ons indicate that the confluence of the Ta 1 keetna, Chulitna and
Susitna rivers (RM 99) is a probable chinook salmon mill·ing area and also that
some upper Susitna River chinook salmon stocks use lower Devil Canyon (RM 151)
as a milling area.
1981 chinook salmon escapement in the Susitna River basin was generally above
average based on comparative recent year surveys.
Sockeye, pink, chum and coho salmon escapements and timing were documented at
each mainstem sampling station. The data indicate that the majority of 1981
Susitna River sockeye, pink, chum and coho salmon escapement originated in the
Susitna River reach above (upstream of) the Yentna River confluence (RM 28).
Escapement samples collected from fishwheel interceptions indicate average
length differences in sockeye and pink salmon stocks between the Yentna River
subdrainages and the Susitna River basin above the Yentna River confluence.
Scale samples collected at the mainstem sampling stations indicate Susitna
River sockeye, chum and coho salmon stocks were comprised predominantly of age
52 , 41 and 43 fish respectively.
Twelve Susitna River mainstem salmon spawning sites were located between RM
64.5 and RM 135.2. Chum salmon were found spawning at 10 of the sites and
coho salmon were recorded spawning in the same area as chum salmon at two
sites.
E-1-2
Sockeye, chum and coho salmon were gill netted in the Susitna River mainstem
less than one mile below Devil Canyon (RM 151) indicati-ng a milling area
exists in the lower canyon.
Eight additional salmon spawning sloughs and streams were identified in the
Susitna River reach between the Chulitna River (RM 99) and Devil Canyon (RM
151).
Radio telemetry tagging investigations on chum and coho salmon indicate that
both species display milling behavior in the Susitna River mainstem above
Ta.lkeetna (RM 99). Coho salmon displayed the greatest milling movement; radio
tagged coho salmon were found in the Susitna River several miles upstream of
their spawning area. Necropsies of radio tagged coho and chum salmon indicate
successful spawning occurred.

2. INTRODUCTION
This Phase I Final Draft Report of the Adult Anadromous Fisheries project
presents the data collected on the five species of adult salmon in Susitna
River by the Alaska Department of Fish and Game (ADF&G) during the 1981 Su
Hydro Aquatic Studies. The five species found in the Susitna River are:
Chinook Salmon, Oncorhynchus tshawytscha
Sockeye Salmon, Oncorhynchus nerka
Pink Salmon, Oncorhynchus gorbuscha
Chum Salmon, Oncorhynchus keta
Coho Salmon, Oncorhynchus kisutch
These studies are part of the Fish Ecology (Subtask 7.10) Phase I studies for
the Susitna Hydroelectric Project.
The primary objectives of the fish ecology studies for the Susitna Hydro-
electric Project are to: (1) describe the fisheries resources of the Susitna
River, (2) assess the impacts of development and operation of the Susitna
Hydroelectric Project on these fisheries resources, and (3) propose the
mitigation measures to minimize adverse impacts (Alaska Power Authority
Susitna Hydroelectric Project, Environmental Studies Procedures Manual,
Subtask 7.10, Fish Ecology Impact Assessment and mitigation planning; prepared
by Terrestrial Environmental Specialists August 1981). The task of meeting
the first of these study objectives is the responsibility of the ADF&G under a
reimbursable services agreement (RSA) with the Alaska Power Authority and the
second and third are the responsibility of Terrestrial Environmental
Specialists (TES).

4. METHODS
4.1 Mainstem Escapement Sampling
Five escapement monitoring stations were established in early June 1981 at the
locations identified in Figure E.4.1. Individual 'site description maps are
provided in Figures EA-1 through EA-5. The operating dates and gear deployed
at these sites were as listed in Table E.4.1. Yentna, Sunshine, Talkeetna and
Curry stations were operated under the direction of Su Hydro, Adult Anadromous
Investigations personnel. Susitna Station was operated by Alaska Department
of Fish and Game, Commercial Fisheries Division personnel.

The side scan sonar (SSS) counters used at the escapement monitoring stations
were deployed and monitored by trained personnel in accordance with the 1980
Side Scan Sonar Counter Installation and Operational Manual written by the
Bendix Corporation (1980). A brief narrative of how a sonar works is provided
in the following paragraph.
A sonar counter essentially coverts electrical energy into acoustical energy
(sound waves) and counts underwater targets by measuring changes in acoustical
echoes. Each SSS counter is composed of a transducer, aluminum substrate with
reflector (target), an electronic-printer, a 12 volt battery, a solar charger
and attendant cableware (Figures E.4.2 and E.4.3). The transducer is verti-·
cally mounted on the shore end of the substrate and emits repeating sound
signals in a conical 2° and 4° alternating, beam just above the substrate. The
transducer also receives returning echoes from the target which is mounted
vertically on the offshore end of the substrate. The entire substrate rests
on the bottom, perpendicular to the shore. As upstream migrant fish pass over
the substrate, they reflect transmitted sound waves back to the transducer and
are then recorded as counts on the electronic counter-printer. The counter-
printer tallies the counts and hourly provides a print-out of the number of
fish passing over each of 12 lineal substrate sectors.
During the 1981 season, each SSS counter was monitored with an oscilloscope a
minimum of four times daily for 30 minutes. Fish related echoes displayed on
the oscilloscope were hand tallied. The ratio of oscil1oscope counts attri-
buted to fish and SSS counts were compared and used to adjust the counter for
accuracy. A fishwheel was operated near each counter to provide species
composition data for apportioning sonar counts.

The fishwheels used at each project location were of identical design with two
baskets and two paddles (Figure E.4.4). Floatation was provided by styrofoam
logs shielded by a plywood frame. The baskets had an average length, width
and depth of 2.4, 1.7 and 0.6 meters (m) respectively and were constructed of
native spruce poles. The basket frames were covered with 7.6 centimeter (em)
rubber coated fencing material which was replaced during the season on most
baskets by similar size, creosote coated webbing. The paddles were also made
from spruce poles of the same length and width as the baskets. The fishwheel
axles were built from 20.3 em squared spruce logs capped at each end with a
steel collar that held a 3.8 em steel shaft set into self adjusting bearing
blocks. The bearing blocks were bolted to an adjustable wood frame that per-
mitted the axle to be raised or lowered at 15.2 em steps to a minimum and
maximum height of 30.5 and 122 em, respectively, above the top of the floats.
A 122 em 1 ong, 76.2 em wide and 122 em deep 1 ive box was attached to the
inshore side of each fishwheel.
Each fishwheel was held in position by a cable bridle anchored to an onshore
deadman and by an inshore mounted boom 1 og 1 odged between the bank and the
inshore float. An inshore weir was used on each wheel, except those at
Sunshine Station to deflect inshore migrants into the fishing area of the
baskets. Weir panels were constructed of alder and willow poles vertically
spaced on 2.5 to 5.1 em centers or when available from 7.6 em mesh, fencing
material.
Each weir was built to conform to the river bottom at the location of instal-
lation and extended from the shore perpendicular to the downstream end of the

livebox. Weirs were not used at Sunshine Station because of debris problems.
All fishwheels were adjusted daily to insure the baskets fished within 15.2 em
or less of the bottom. Depending on site characteristics, primarily river
velocity, the wheels rotated at speeds ranging from 2.0 to 5.5 revolutions per
minute (rpm). The preferred speed was 2.5 rpm based on design.
All fishwheels were scheduled to operate continuously, 24 hours per day.
However, due to occasional fl coding and excessive debris, rna i ntenance and
repair work, and at Sunshine Station because of periodically high catches
which could not always be processed due to safety and personnel constraints,
continuous operation was not always possible. Sampling checks were usually
made four or more times daily at each fishwheel.
Age, length and sex samples were collected daily at each sampling station from
all fishwheel caught chinook .salmon and from 40 sockeye, 25 chum, and 25 coho
salmon. Age samples were obtained by removing the 11 preferred 11 scale located
two rows above the lateral line on a diagonal from the posterior insertion of
the dorsal fin to the anterior insertion of the anal fin. Sex was determined
from morphologic characteristics. Fork Length (FL) measurements were taken
from mid-eye to fork of the tail and recorded to the nearest millimeter (mm).
Pink salmon, exclusively two year old fish, were sampled only for length and
sex at a rate of 40 per day per station. Average processing time for col-
lection of age, length and sex samples per fish usually ranged between 20 and
30 seconds. All fish were immediately released following sampling.
E-4-8
All fishwheel intercepted sockeye, pink, chum and coho salmon at Sunshine,
Talkeetna and Curry stations were tagged. An exception was that on three
non-consecutive days at Sunshine Station an insufficient number of tags were
on location to tag the entire catch. Two types of tags were used (Table
E.4.2.). At Sunshine and Talkeetna stations color coded Floy-4 spaghetti tags
were deployed. Petersen disc tags, 2.5 em in diameter, were used at Curry
Station. The Petersen disc tags were inserted through the cartilage immedi-
ately ventral to the insertion of the dorsa 1 fin. Buffer discs, 20.6 em in
diameter, were used to prevent the tagging pins from wearing through the
Petersen disc and causing tag loss. Flay FT-4 spaghetti tags were inserted in
same location as the Petersen disc tags and each was secured against the back
of the fish by a tightly drawn overhand knot. Tagging time per individual
fish ranged from 10 to 30 seconds. All fish were released immediately after
tagging.

4.2 Survey Investigations
4.2.1 Chinook Salmon Escapement Surveys
Chinook salmon escapement surveys were initiated in the third week of July and
terminated in the second week of August. Surveys were performed by heli-
copter, single engine fixed-wing aircraft and in one instance, by foot.
Surveyors wore polaroid sunglasses to enhance their ability to observe and
enumerate fish. Estimation counts were held to a minimum and the majority of
the fish were individually enumerated with hand held tally counters.
4.2.2 Sockeye, Pink, Chum and Coho Salmon Surveys
4.2.2. 1 Mainstem Surveys
From mid July to early October, a survey crew was assigned to each of three
subreaches of the Susitna River mainstem between the estuary and Devil Canyon
as outlined below:

The crews used a combination of drift gill nets, electroshockers, echo
recorders and egg deposition pumps to sample the mainstem Susitna River for
presence or absence of mainstem spawning activity. Drift gill nets were
deployed over a wide range of sites. Site selection was based on a brief
visual assessment of the following criteria which generally suggested suita-
bility of a particular site as a spawning area and the feasibility of
operating a drift net:
1. S~bstrate composition
2. Relative water velocity
3. Water turbidity
4. Water depth
5. Presence of debris
6. Presence of spawned out fish
or fish surfacing.
Several times in the season high water conditions obscured many of the visual
parameters used to identify potentia 1 spawning sites. When this occurred,
aerial photographs taken earlier during low water flows were examined and,
from the photos, likely spawning areas were identified and sampled.
Drift gill nets used in sampling the mainstem were 15.2 m long, 1.5 m deep,
13.3 em stretch mesh nylon web, and were fished from 6.1 m flat bottom river-
boats each equipped with a 75 horsepower jet outboard. A net was typically
deployed by casting one end into the river from the bow of the boat as it
moved slowly in reverse. The other end of the net was tied to the bow and the
boat was then maneuvered in a manner that the net extended semi-perpendicular
to the river current. Surface and subsurface debris along with fluctuating
E-4-11
depths generally governed the distance fished. These same nets were used in
areas that were either too shallow or too narrow to sample effectively by the
drifting technique. In some cases, the net was used as a set net by anchoring
one end to the boat bow and the other end to a portable anchor or natural
deadman. In other instances, the net was deployed as a seine by manual means.
Salmon caught by drift netting, seining or by set netting were not assumed to
be spawning at the catch location unless the criteria listed below were met:
1. Fish exhibits spawning maturation color and morphology and;
2. Fish expels eggs or milt when slight pressure is exerted on .the abdomen
and;
3. Fish is in vigorous condition, with an estimated 25 percent or more of
the eggs or milt remaining in the body cavity and;
4. Additional fish are provided from the site that meet criteria 1 through 3
above.
Survey crews were equipped with a Lowrance Model LRG-15108 echo recorder to
survey the Susitna River mainstem for salmon spawning activity. The plan was
to locate fish by directing the transducer beam horizontally across the river
bed. A horizontal mode was chosen because of the limitation of vertical scans
due to restricted water depths in the mainstem. In conducting a horizontal
E-4-12
side scan the recording unit was nearly always tuned to record at the 9.1 or
the 18.2 m range to take advantage of refined dimension in resolution and
detail on the graph printout. The sens.itivity setting on the recorder was set
at the 3/4 point or higher for additional detail. The transducer was attached
to an adjustable aluminum gunnel bracket that allowed it to be lowered into
the water column at various depths. Echo recordings were taken with the
transducer in the horizontal mode at depth ranges from 61 em from the surface
to 30 em from the bottom. Sites surveyed were generally semi-placid areas of
the river due to the 1 imited ability of the transducer bracket to withstand
water force without bending or breaking.
The survey crews electroshocked areas of the mainstem Susitna River with a
Model VVP-3C Coffelt electroshocker, using a 3500 watt Homelite generator as a
power source (Figure E.4.5). Input to the electroshocking unit was 230 volts
alternating current (A. C.) and output voltage was one of three types, A. C.,
direct current {D.C.), or pulsating D.C. One to three and one half amps of
D.C. or pulsating D.C. was found to be effective capturing adult salmon. The
output power was split with one lead going to a foot switch and the other to
the electrodes; the anode (+) electrode being the dip net and the cathode (-)
electrode the boat. Depression of a foot switch allowed the flow of current
through the water. The activation period ranged from five to 10 se·conds
followed by a 20 to 40 second pause to avoid a possible herding effect on
fish. Safety was accomplished through the use of rubber boots and gloves; in
addition, a kill switch was attached to the generator and kept in a ready
position by the boat operator at all times.

Egg deposition sampling was conducted with a Homelite two cycle, single stage,
backpack mounted water pump and two circular, standing screen baskets with cod
end nets. Each basket sampled a 1,800 cm 2 area. The height of the basket was
45.7 em. Sampling with this gear was limited to areas of not more than 45.7
em deep and where electroshocking or gill netting produced fish which met the
previously defined criteria for spawning or where visual surveys earlier in
the season .revealed suspect redds or spawning activity.
From late July to mid September, the Gold Creek survey crew fished four hours
every five days, one -15.2 111 1 ong, 1 . 5 m deep, 13.3 em stretched mesh nylon
gill net in eddies in the Susitna River mainstem between Devil Canyon and RM
149.4, 1/2 mile above Portage Creek. The gill net was staked at one end :to
the shore and held off shore at the other end in a slight downstream arc by a
35 pound Navy anchor. Species and spawning conditions were recorded on all
gill net caught fish.
4.2.2.2 Slough and Tributary Stream Surveys
The Sunshine and Gold Creek survey crews conducted adult salmon enumeration
counts on all spring fed sloughs and tributary streams between the Chulitna
River and Devil Canyon on a weekly basis. In addition, the Sunshine survey
crew made tag recovery counts at pre-selected times on several known spawning
tributaries between Sunshine Station and the Chulitna River confluence (Table
E.4.3.).

The spawning ground surveys were performed on foot by two crew members. One
counted live fish and the other counted carcasses. Tag recovery counts were
made at the same time by the crew member enumerating live fish. Tag type and
color were recorded by species on each live fish bearing a tag. The second
crew member removed tags from carcasses and recorded the tag type, number and
color, and species.

4.3 Radio Telemetry Investigations
Radio tracking operations were effected on chinook, chum and coho salmon. A
sample size of 16 chinook, ll chum and 10 coho salmon was selected. The radio
telemetry transmitters, receivers, and antennas were obtained from the Smith-
Root Corporation, Vancouver, Washington. All transmitters used were Model
P-40. The antennas used were a loop antenna Model LA-40 and a paddle antenna
Model PA-40. The two type of receivers used were a manual receiver Model
RF-40 and a scanning receiver Model SR-40. Each transmitter was individually
identifiable and operated on a carrier frequency ranging from 40.650 to 40.740
MHZ. Transmitter life expectancy was 75 to 90 days.
Two transmitter sizes were used. The larger transmitters measured 9.7 em
long, 1.9 em wide, supported a 16.5 em long antenna and weighed 38.6 grams.
The smaller transmitters weighed 23.6 grams, measured 7.6 em long, 1.6 em wide
and had a 13.0 em long antenna. Each transmitter was sealed in a rubber
coated, waterproofed plastic case and was equipped with an external,
insulated, water tight antenna. A small bar magnet was taped to each trans-
mitter to break the electrical circuit and conserve battery life until used.
The larger (38.6 grams) transmitters were used on chinook salmon exceeding
87.6 em FL. The smaller (23.6 grams) transmitters were inserted in lesser
sized chinook salmon and were used entirely in radio tracking chum and coho
salmon.
Prior to field operations, the radio transmitters were immersed in water for
48 hours and tested for signal strength and frequency on both manual_ and
scanning receivers. Malfunction a l transmitters were returned to the manu-
E-4-17
facturer for repair. To enable anglers to return the transmitter and catch
data to project personnel, adhesive waterproof 1 abel s were affixed to those
transmitters which tested satisfactorily.
All chinook salmon selected for radio tagging were captured by fishwheels and
processed similarly at the Talkeetna and Curry Stations. Those fish visually
judged longer than 80.6 em FL were transferred by a standard dip net from the
fishwheel holding box to a wooden tank containing approximately 15 liters of
fresh water. After a few minutes the fish usually calmed and was examined
briefly for external injuries and spawning condition. Vigor was appraised
prior to and during th1s inspection and any fish displaying little or no
movement or loss of equilibrium was deemed 11 Stressed 11
• Fish containing fresh
wounds or which were less than 76.2 em and/or those fitting the definition of
11 Stressed 11 were classified as unsuitable for tagging. Stressed fish were
removed from the box and held in shallow, slow moving water by hand until they
revived and forcefully swam away. Processing continued using this criteria
until a fish suitable for tagging was encountered.
After a fish was examined and found to be suitable for tagging, preparations
were made for implantation of the radio transmitter. Tricaine methanesul-
fonate (MS-22~, an anesthetic, was sprinkled sparingly into the holding tank
in an amount that caused a slight decrease in opercular movement followed by
loss of equilibrium within two to five minutes. Slightly more anesthetic was
added if the fish remained active after the first application.
Once anesthetized, the sex of the fish was determined by external examination
of morphological characteristics. Next, a FL measurement was taken and
E-4-18
several scales were removed from the preferred zone for age determination.
The fish was then suspended in a moistened canvas s 1 i ng and weighed to the
nearest 0.1 kg and returned to the anesthetic tank. As the fish was held
firmly against one side of the tank a numbered Petersen disc with buffer pad
was mounted on a presharpened needle and inserted about 2.5 em beneath the
second dorsal fin ray. 'A blank Petersen disc was then slipped on ttie pro-
truding needle, and the disc snugged against the flesh by twisting the needle
firmly against the blank disc. The measuring, weighing, scale collection and
Petersen disc tagging process usually took 60 to 90 seconds.
Prior to insertion the radio tag was checked for a final time while submerged
in a container of water and tested for signal strength and frequency of
transmission. After testing, a #2, nickel finish, beak hook was tied to the
free end of the antenna wire. The antenna, with attached hook, was p 1 aced
hook first into a 1.95 em diameter, 50.2 em long plexiglass tube which served
as an insertion instrument. A wider, 2.5 em diameter, 32.4 em long plexiglass
tube was slid over the small tube until the transmitter was cradled in the
larger tube. Glycerine, a water soluble lubricant, was liberally poured on
the transmitter to ease insertion in the fish. As one person held the fish
ventral side up with the head elevated at about a 45° angle, the other person
inserted both tubes and the transmitter to the fish 1 S esophagus. The smaller
rod was slowly pushed inward until the transmitter disappeared from view into
the stomach. The fish was immediately immersed for 20 to 30 seconds and
lifted again at the same angle. The antenna hook was positioned slightly off
center in the roof of the mouth to prevent rupturing a major artery. Pressure
was applied until the barb protruded (Figure E.4.6.). Verification was then
made to determine if the transmitter was correctly pas iti oned. Next, water

was removed from the tank and fresh water was added to a 11 ow the fish to
recover from the anesthetic. Four to eight water changes were usually
required for recovery depending on the amount of MS-22~ used. Once the fish
displayed increased muscular and opercular activity. it was removed from the
tank and held by hand in the river until it forcefully swam away. Tag
implantation and antenna anchoring usually took two to three minutes. Total
elapsed time for the entire tagging process between introduction of MS-222R
and first addition of fresh river water varied from eight .to 12 minutes.
depending on how long it took the fish to become sedated. Recovery times from
the anesthetic ranged from seven to 30 minutes depending on the amount of
MS-22P used.
Preliminary literature research revealed no information about internal radio
transmitter implants in chum salmon. In late July. three adult chum salmon
were experimentally radio tagged with dummy transmitters to ascertain whether
the method used on chinook salmon would be suitable. The chum salmon were
taken from Sunsh•ine Station fishwheels. The first experimentally implanted
transmitter was positioned in the posterior of the stomach [Figure E.4.7 (A)].
Immediately after tagging. the fish was pithed and necropsied. The stomach
was found to be very thin walled and had ruptured. The tear was 5.3 em long
and extended from the posterior end of the transmitter toward the fish • s
mouth. The second and third chum salmon experimental implants were made in
progressively anterior positions. posterior of the esophagial sphincter
muscle. Despite the anterior transmitter location the thin walled stomachs

E-4-22
ruptured [Figure E.4.7 (B-C)]. The antenna also extended too far forward ·in
the fish•s mouth, causing it to sag and become entangled in the lower jaw and
gi 11 s.
From these results the decision wa:s made to implant the transmitter in the
anterior portion of the stomach cavity in chum salmon [Figure E.4.7 (D)].
This location was determined to be the point at which the anterior (antenna)
end of the transmitter just disappeared from sight behind the esophagial
sphincter. When so positioned, the rubber coated reinforcement at the
antenna/transmitter connection point was barely visible in the rear of the
fish•·s mouth.
The problem of antenna placement was remedied by lacing the antenna through
the fish•s kype. To accomplish this the hook method was rejected and an
extension was added to the antenna. A 15 em piece of heat-to-shrink
material, a wire insulating material made of plastic, was fastened to the
anterior two em of the antenna. Following transmitter implantation a hollow
Flay tagging needle was used to pierce the kype from inside the mouth. Care
was taken to avoid puncturing the major artery that·lies at the center of the
roof of the mouth. The heat-to-shrink material was slid into the hollow
needle and the needle pulled through the kype, lacing the elongated antenna
through the tissue. This allowed maximum extension of the antenna without
damage to gills and simultaneously suspended the antenna so that signal
transmission was enhanced. The antenna extension was secured to the dorsal
surface of the kype by crimping one-half of a precut size 10/12 electrical
E-4-23
butt splice on the heat-to-shrink material. A plastic buffer pad was placed
between the flesh and the butt splice to prevent tissue damage. Any excess
heat-to-shrink material above the butt splice was then removed.
Radio transmitter implantation methodology for coho salmon was initially
identical to that described for chum salmon, however transmitter and antenna
modifications were required to prevent transmitter regurgitation by adult coho
salmon. The first two tagged coho salmon were released with extremely
anterior implanted transmitters with the heat-to-shrink material antenna
modification. The third coho salmon which was radio tagged following the same
procedure used on the first two fish, regurgitated the transmitter before
recovering from the anesthetic.
To prevent future transmitter regurgitation by coho salmon, a wire modifi-
cation was adopted. A 30 em long piece of 16 gauge baling wire was wrapped
twice around, the anterior tip of the transmitter and extended forward,
parallel to the antenna. Several wraps of waterproof plastic tape secured the
wire to the transmitter. The tip of the antenna was extended and taped to the
wire to enhance signal transmission and prevent possible abrasion to the fish.
Regurgitation of radio transmitters has been evidenced in at least one other
study. Two of 23 adult coho salmon evidently regurgitated radio transmitters
(identical to those used in this study, but without antenna modifications)
downstream of their release sites in the White River, Puget Sound, Washington
(personal communication, Don Chapman). The transmitters in the White River
coho study were lubricated and esophogically implanted with the antenna
E-4-24
trailing through the operculur rather than being anchored to the kype as they
were in the Susitna River study.
The technique adopted to implant radio tags in coho salmon was almost identi-
cal to that used for chum salmon, however prior to pushing the sharpened wire
through the kype, an outward facing loop was made, so that it rested against
the inside of the kype. A buffer was then snugged against the dorsal side of
the kype and one half of an electrical connection was crimped over the wire
and against the buffer. The wire loop and buffer-crimp combination prevented
the transmitter from moving forward and being regurgitated by the fish.
When chinook, chum and coho salmon were being implanted with radio tags the
fishwheel, at the tagging site, was shutdown and kept deactivated for 20
minutes following release to prevent possible recapture. Each radio tagged
fish was monitored with a loop or paddle antenna for 10 to 20 minutes after
being tagged. (Figure E.4.8).
Fish tracking was conducted by boat along the mainstem Susitna River from RM
99.0 to as far upstream as RM 142.0. The boat used was a 6.6 m Wooldridge
riverboat powered by a 460 cm 3 four cylinder inboard engine with a two-stage
Hamilton jet. Tracking occurred at one to four day intervals depending on
stream flow conditions and fish distribution.
Fish track·ing was conducted using both manual and scanning receivers. Both
receivers were encased in a waterproof wood box. A 1 oop antenna and an
outdoor speaker were connected to the scanning receiver to detect and signal

the occurrence of a radio tagged fish while monitoring from the boat. A
sma 11 er paddle antenna was connected to the manu a 1 receiver to pinpoint a
tagged fish's location to within six meters. While the scanning receiver
automatically searched all transmitter frequencies in use, the individual
operating the manual tracker scanned specific transmitter frequencies when a
tagged fish was detected. A triangulation procedure was implemented by
rotating the loop antenna slowly from various river locations. The position
of the fish was determined and its location plotted on black and white aerial
photographs (scale 1 :40,000) of the river. Its position was then logged to
the nearest 0.1 river mile.
Monitoring a tagged fish was conducted by air at one to four day intervals
from a Cessna 185 aircraft. A loop antenna was fastened to each wing strut
with hose clamps. The antennas were fixed parallel to the fuselage with the
handle facing forward. The broad face of the loop faced the fuselage and the
narrow surface of the loop was perpendicular to the ground. One antenna was
connected to a manual receiver and the other to a scanning receiver inside the
a i rpl'ane. Each antenna cord was reinforced with duct tape where it passed
through the doorway. A speaker was connected to the scanning receiver and
headphones to the manual receiver. The manual receiver was monitored by one
person while the other monitored the scanning receiver and plotted the
position of the aircraft. Locations of tagged fish were identified by signal
strength to + 0.1 mile and marked on vinyl encased, black and white aerial
photographs (scale 1:40,000).

4.4 Data Analysis
Population est·imates presented in the report were calculated using the fol-
lowing formulas (Ricker, 1975):
1\ N = mclr
Where: m =Number of fish marked (adjusted for tag loss).
c =Total of fish examined for marks during sampling census
r =Total number of marked fish observed during sampling census
~ = Population estimate
The 95% confidence limits around N were determined by using the formula (Dixon
and Massey, 1969):

Tag loss was calculated using data derived from repeated spawning ground
surveys of placid sloughs where survey conditions permitted unr.estri cted

{visual) observation of tag loss through inspection of spawning areas for shed
tags and accurate enumeration of fish with tags in place. In calculating tag
loss, the number of tagged fish examined (t) were summed with the number of
loose tags (1) respective to tag type. The resulting summation (1 + t) was
then divided into the number of fish with tags (t) in place to provide a
percentage on tag retention (R). The above is mathematically stated in the
formula: t = R x 100%.
l+t
The percentage was then multiplied by the number of fish by species tagged at
the particular tagging location being examined, for an appropriation adjust-
ment to the number of fish released.
Age determination was made by scale examination using a portable microfiche
reader and the age class described using Gilbert-Rich notation. By the
notation, age 42 fish are those fish returning in their fourth year of life
that migrated from freshwater to the marine environment in their second year
of life having spent one winter rearing in fresh water.

5. RESULTS AND DISCUSSION
5.1. Chinook Salmon Investigations
5.1.1 Mainstem Escapement Sampling
Presented in Table E.5.1 is a summary of the number of chinook salmon counted
by SSS counters at each station on the Susitna and Yentna rivers.
Table E.5.1. Apportioned sonar counts of chinook salmon by sampling station,
Adult Anadromous Investigations, Su Hydro, 1981.
Sampling Sonar Chinook Salmon
Location Operating Period Counted
Susitna Station 27 June - 2 September 1,752
Yentna Station 29 June - 7
September 427
Sunshine Station 23 June -15 September 2,415
Talkeetna Station 22 June -15 September 1,154
Daily SSS counts for each station are provided in Appendix EA. These counts
are not total es'capement estimates for the periods sampled because of two
unknowns: (1) the proportion of the fish migrating beyond the range of the
counters and (2) the selectivity of the fishwheels which were used to
apportion the counts. The counts reported in Table E.5.1 are, therefore, an
E-5-1
index of the number of chinook salmon which passed each of the sampling
stations during the period when the sonars were in place.
The sonar counters and. fishwheels at Susitna Station (RM 26.7) were
operational on 27 June. Based on previous investigations, the majority of the
chinook salmon escapement had already migrated past Susitna Station by this
date (ADF&G, 1972) and therefore it is considered that Susitna Station was not
operated early enough in the season to accurately define the beginning or the
mid point of the migration. Between 27 June and ~September a total of 1,752
chinook salmon passed over the sonar counters (Table E.5.1). A plot of the
daily sonar counts and mean hourly fishwheel catches is provided in Figures
E.5.1 and E.5.2 respectively. Fishwheel catches indicate the migration ended
by 9 July.
Yentna Station, located at RM 04 on the Yentna River approximately six miles
above Susitna Station, also was not operated early enough in the season to
fully define the migration timing of chinook salmon past this site. Daily
sonar counts of chinook salmon are graphically presented in Figure E.5.1. A
total of 427 chinook salmon were counted over the sonar counters between 29
June and 7 September. Mean hourly fishwheel catches are presented in Figure
E.5.2 and indicate the migration was over by 9 July.
Sunshine Station (RM 80) was operational on 23 June. The sonar counters
enumerated 2,415 chinook salmon between 23 June and 15 September. Based on
sonar counts and fishwheel catch data, the chinook salmon migration can be
determined to have occurred on or before 23 June (Figures E.5.1 and E.5.3).
The migration essentially ended on 10 July.

Figure E.5.3. Mean hourly fishwheel catch by two day periods of chinook salmon at Sunshine Station,
Adult Anadromous Investigations, Su Hydro Studies, 1981.
A total of 1,154 chinook salmon were enumerated over the sonar counters at
Talkeetna Station (RM 103) between 22 June and 15 September. The sonar and
fishwheel rate curves (Figures E.5.1 and E.5.4) indicate that an undetermined
proportion of the escapement had-already migrated past Talkeetna Station
before the site was operational. The peak of the migration as evaluated from
the sonar and fishwheel data occurred on or before 22 June and the migration
essentially ended on 7 July.
At Curry Station {RM 120), the chinook salmon migration was intercepted in
sufficient time to clearly define timing (Figure E.5. 5). Migrating chinook
sa 1 man reached Curry on 16 June. The migration peaked on 23 ·June and was
principally over by 4 July.
Delayed surges occurred in fishwheel catches of chinook salmon at Sunshine,
Talkeetna and Curry stations. A comparison of catch rates and provisional
USGS discharge data indicate a resumption of upstream migration following
periods of high water (Figures E.5.2 -E.5.6). The sonar counts plotted for
Sunshine and Talkeetna support this assumption {Figure E.5.1). Low catch
rates exhibited by the Sunshine and Talkeetna fishwheels during this period
are possibly attributable to low wheel efficiency at those flow rates.
Fishwheel catch rates during peak migration periods indicate a preference by
chinook salmon for one bank over the other if wheel efficiency and placement
are not considered (Figures E.5.2 -E.5.5). Migrating adults may have
preferred the east bank during peak migration periods at the Sunshine and
Ta 1 keetna sites whi 1 e the west bank was preferred at Curry. However, the
sonar counter at Sunshine and Talkeetna Stations do not indicate a strong

preference by chinook salmon for utilizing one bank or the other (Appendix
EA). Any short term preference exhibited may be in response to changes in
discharge, among other factors, which could be determined conclusively through
subsequent research efforts.
The age class frequencies of chinook salmon sampled at each station are
presented in Table E.5.2. Because the migration had essentially passed by the
time Susitna and Yentna stations were in operation, the samples collected at
these sites are not representative of the entire escapement. The data does
indicate that the majority of the Susitna Station fish were three and four
year old fish. Each accounted for 39.4 percent of the sample. Next abundant
at Susitna Station were five and six year old fish representing 12.1 percent
and 9.1 percent of the sample respectively. Analysis of the freshwater ages
of these fish indicate that all (100%) migrated to the ocean in their second
year of life after one winter rearing in freshwater.
At Yentna Station four year old chinook salmon were most abundant (40.5%),
followed by six (27.1%), three (18.9%), and five (13.5%) year old fish (Table
E.5.2). Ninety-seven percent of these fish had smolted in their second year
of life after spending one winter as fry in freshwater. The balance (3%)
spent less than one winter rearing in freshwater before outmigrating to the
ocean.
Escapement samples collected at Sunshine Station indicat·e that four year old
fish were dominant (31.9%), followed by three (27.6%), five (23.0%), and six
(16.9%) year old fish (Table E.5.2). Seven year old fish comprised only 0.5
E-5-11
percent of the sample. Approximately five percent· of the chinook salmon
sampled at Sunshine Station had spent less than one w·inter in freshwater
before migrating to sea. The rest of the fish (95%) had completed a full
winter of growth before migrating.
Four and six year old chinook salmon were equally abundant at Talkeetna
Station and comprised approximately 60 percent of the sample (Table E.5.2).
The next most abundant were five year old fish (21.4%) followed by three
(15.7%) and seven (2.9%) year old fish. Approximately 11 percent of the
chinook salmon sampled at Talkeetna Station had spent less than one winter in
freshwater before migrating to the ocean whi 1 e about 89 percent of the fish
had completed one winter in freshwater before migrating.
Curry Station samples showed a dominance of four year old fish (34.3%),
followed by five (27.8%), six (19.4%} and three (18.5%) year old fish (Table
E.5.2). Comparing the freshwater ages, 11.7 percent had spent less than one
winter in freshwater before smolting and 88.3 percent had completed one
winter.
The age samples collected at Sunshine, Talkeetna and Curry stations can be
considered characteristic of the escapement. Sunshine Station had a signifi-
cantly higher percentage of younger fish, mainly three years old, passing that
site than at Talkeetna Station of Curry Station (Figure E.5.7). With the
exception of Talkeetna Station, four year old fish were highest in abundance
at all sampling sites. At Talkeetna Station, six year old fish were equally
as abundant as four year old fish. Seven year old fish were relatively

scarce, representing only 0.5 percent and 2.9 percent of the Sunshine Station
and Talkeetna Station fish respectively. No seven year old fish were found in
the Curry Station sample.
~
An almost equal percentage, 11.3 percent and 11.7 percent respectively, of the
adult chinook salmon sampled at Talkeetna Station and Curry Station had spent
less than one winter as fry in freshwater before migrating to sea (Table
E.5.2). The balance, had outmigrated to the ocean after completing one winter
of rearing in freshwater. In comparison, five percent of the Sunshine Station
fish had smolted before their first winter and 95 percent after one winter.
Fork length data segregated by age and sex indicate the fish at Talkeetna and
Curry stations were significantly larger than those intercepted at Sunshine
Station (Table E.5.3 and Figures E.5.8 and E.5.9). The freshwater age data
indicate that a higher percentage of the adult fish sampled at both Talkeetna
Station and Curry Station smolted at an earlier age than the fish sampled at
Sunshine Station. A possible explanation for Ta"lkeetna and Curry Station fish
being larger in each age class is that they averaged more feeding time in the
marine environment than similar age class fish sampled at Sunshine Station.
At all sampling sites, male chinook salmon were present in each age class and
were more abundant than females in the age three, four, and five year old
classes (Table E.5.4). Females were more abundant than males in the six year
age class and equally numerous as males in the seven year old class. The data
from Sunshine, Talkeetna and Curry stations are similar except that there were

no four year old females sampled at Talkeetna Station, and 15.2 percent and
.30.8 percent respectively of the Sunshine and Curry stations four year old
fish were females.
Figures E.5.10 through E.5.12 present a graphic illustration of the frequency
of male and female chinook salmon by fork length sampled at Sunshine,
Talkeetna and Curry stations. These graphs indicate that males were more
frequent in the shorter length ranges and correspondingly, females were more
abundant in the longer length ranges.
The number of chinook salmon length measurements as obtained from fishwheels
at Susitna and Yentna stations was too small to permit significant data
reduction.
5.1.2 Radio Telemetry Investigations
Sixteen adult chinook salmon were tagged from 22 June through 19 July with
radio transmitters and their movements monitored during June, July and August
of 1981 (Table E.5.5). Four fish were tagged at Talkeetna Station (RM 103)
and 12 fish were tagged at Curry Station (RM 120) (Figure E.5.13).
The confluence of the Talkeetna, Chulitna and Susitna rivers, defined here as
the Three Rivers Area (TRA), is a probable milling area for adult chinook
salmon. All four radio tagged fish at the Talkeetna site moved downstream and
remained at or downst'f'eam of the TRA for several days to weeks before either
migrating back upstream in the Susitna River or entering the Talkeetna River

(Figure E.5.14). For example, fish bearing radio tag number 660-3, which was
tagged on 1 July, moved downstream to· the TRA within 24 hours, entered the
Talkeetna River two or three days later and was detected on 30 July in Prairie
Creek (RM 50.1), a Talkeetna River tributary. Another fish bearing radio tag
number 600-1, displayed two downstream-upstream surges in the TRA prior to
ascending and remaining in the Susitna River at RM 123.5. The other two fish
tagged at Talkeetna Station bearing transmitter numbers 610-2 and 610-3 moved
downstream and remained in the TRA for up to two weeks before migrating back
upstream in the Susitna River and entering Indian River (RM 138.6) and Lane
Creek (RM 113.6) respectively.
Fish radio tagged at Curry Station (RM 120) generally displayed little or no
downstream movement follow·ing transmitter implantation (Figure E.5.14). Eight
of the 12 fish tagged at Curry Station moved upstream within 48 hours. Radio
tagged fish bearing transmitter number 620-2 moved about one mile downstream
to RM 119 after being tagged and remained there for at least 48 hours before
moving back upstream. Fish bearing radio. tag number 620-1 moved downstream
and held position in or near Chase Creek (RM 106.9). Fish bearing radio tag
number 670-3 apparently died from stress associated with handling and trans-
mitter implantation. The transmitter in radio tagged fish number 640-1
apparently malfunctioned shortly after the fish was tagged.

Six radio tagged chinook salmon exhibited 1direct 1 upstream movement in the
Susitna River and entered one of two tributaries, Indian River (RM 138.6) and
Portage Creek (RM 148.9), within five to 12 days after being tagged (Figure
E.5.14). Two of these fish held at two locations in the Susitna River for
several days before entering a tributary stream. Fish bearing radio tag
number 600-2 remained at RM 123.5 for approximately four days prior to moving
upstream and entering Portage Creek, and fish bearing transmitter number 640-3
remained in the Susitna River near the mouth of the Indian River· (RM 138.6)
for 11 days before ascending that stream.
Three chinook salmon radio tagged at Curry Station (RM 120) displayed
1 indirect• upstream movement within the Susitna River (Figure E.5.14). Fish
bearing radio tag number 620-3 was detected within lower Devil Canyon at RM
150.7 and 149.5 on consecutive day overflights before ascending Portage Creek
(RM 148.9) 12 days after being radio tagged. Fish bearing transmitter number
610-1 was detected at RM 151.0 in lower Devil Canyon prior to entering Portage
Creek eight days after being radio tagged. Fish bearing radio tag number
630-1 migrated upstream to the mouth of Portage Creek ( RM 148.9), nine days
after being tagged. On the tenth day, this fish moved downstream ten miles
and entered Indian River (RM 138.6).
Radio tagged chinook salmon displayed a variety of upstream movement rates
within the Susitna River. For example, fish bearing transmitter number 730-1
was detected at the mouth of Portage Creek ( RM 148.9) 1 ess than five days
E-5-27
(105.75 hours) after being radio tagged at R~1 120.7. This represents an
overall upstream migration rate of 0.26 mile per hour (mph) or 6.4 miles per
day. The fastest short-term upstream migration rate was exhibited by fish
bearing radio tag number 610-2 when·it moved 1.15 miles upriver in 55 minutes.
This is equivalent to an upstream migration rate 1.26 mph. Fish bearing radio
tag number 600-1 moved 3.7 miles upriver within four hours and five minutes
resulting in an upstream migration rate of 0.91 mph. Radio tagged chinook
salmon in the Klamath River, California displayed similar migration rates
(personal communication, Jon Heifetz).
Chinook salmon which moved upstream after being radio tagged at Talkeetna and
Curry stations generally entered one tributary. However, two of these 11 fish
entered two tributaries. Portage Creek (RM 148.9) supported six radio tagged
fish, Indian River (RM 138.6) attracted five radio tagged fish, and Jack Long
Creek (RM 144.5) and Lane Creek (RM 113.6) each contained one radio tagged
chinook salmon. Fish bearing transmitter number 620-3 remained in Portage
Creek (RM 148.9) for several days and then migrated downstream and entered
Jack Long Creek (RM 144.5). Fish bearing transmitter number 610-2 entered and
exited Indian River (RM 138.6) twice prior to entering and remaining in
Portage Creek (RM 148.9) for several days.
Two fish were detected milling in lower Devil Canyon. One individual, bearing
radio tag number 620-3, was noted at RM 151.7 on 5 July and RM 150.5 on 6
July. Fish bearing radio tag number 610-1 was noted at RM 151.0 on 6 July and
RM 150.0 on 7 July. No tagged fish were detected upstream of RM 151.7.

Appendix EL.
5.1.3 Escapement Surveys
Consistent poor weather conditions basin wide, beginning in early July and
extending through mid August, caused high, turbid water conditions. These
conditions precluded surveys from being conducted or allowed only partial
counts in' many instances. Generally, 1981 chinook surveys were restricted to
small drainages with fluctuating discharges which tended to clear rapidly
between rainy periods. Some larger systems such as the Deshka River,
Alexander Creek and Chunilna (Clear) Creek, which historically have had the
highest escapements were not countable due to consistently high, turbid water
conditions.
The 1981 chinook salmon escapement counts, survey dates, methods and visi-
bility conditions are presented in Table E.5.6. Figure E.5.15 shows the
locations of the streams surveyed. Without repetitious spawning ground counts
and knowledge of the average life expectancy of chinook salmon in each stream
surveyed, the escapement counts cannot be cons ide red an absolute measure of
total escapement. They are, rather, an index of abundance. Neilson and Geen
(1981) foun.d that a single census at the spawning peak measured only 52
percent of the total escapement. Their study also im;luded precocious fish
(Age 31 and 32 ) sometimes referred to as jack salmon. Precocious chinook
salmon are difficult to observe because of their relatively small size (less
than 400 mm) and light coloration, consequently the counts presented in Table

E.5.6 should be considered as only an escapement index of fish four years and
older. Based on fishwheel interception of age 31 , and 32 fish at Sunshine,
Talkeetna and Curry stations, precocious chinook salmon comprised between 16
and 28 percent of the population depending on sampling location (Table E.5.2).
Chinook salmon escapement counts for Susitna River basin streams from 1976 to
1981 are presented in Table E.5.7. Compared to the counts made by ADF&G Sport
Fisheries Division in previous years, 1981 east side Susitna River tributary
st_ream escapements of chinook salmon were above average while the west side
tributary streams in 1981 had average escapements. Comparative surveys on
Indian River and Portage Creek, two important chinook salmon spawning tribu-
taries between Talkeetna and Devil Canyon, indicate the 1981 escapement was
above average.

5.2.1.1 Sockeye Salmon
At Susitna Station 340,232 sockeye were counted (Table E.5.8). Fifty-one
percent of those counted migrated across the east bank SSS counter and 49
percent over the west bank counter. The migration principally extended from
29 June to 24 August with the mid-point occurring on 17 July (Figure E.5.17).
Seventy-five percent of the sockeye escapement passed in a 13 day period from
11 July to 23 July. Fishwheels operating at Susitna Station intercepted a
total of 4,087 sockeye salmon. Fishwheel catch per hour plotted against time
(Figure ED-1) indicates the peak of migration occurred between 10 July and 19
July with the majority of the sockeye salmon migrating along the west bank.
A total of 139,401 sockeye salmon were logged by the SSS counters at Yentna
Station (Table E.5.8). Ninety-two percent migrated over the south bank and
eight percent over the north bank counters. The beginning, mid-point and end
of migration occurred on 1 July, 16 July and 3 August respectively (Figure
E.5.17). Seventy-five percent of the fish passed in a ·12 day period between
12 July and 23 July. A total of 7,000 sockeye were caught in fishwheels at
Yentna Station. Fishwheel catches indicate that the peak of migration
occurred between 13 July and 15 July with the majority of fishwheel inter-
ceptions (70.0%) on the south bank (Figure ED-1).
A total of 89,906 sockeye salmon passed over the SSS counters at Sunshine
Station. Sixty eight and nine-tenths percent were counted on the east bank
sonar and 31.1 percent on the west bank counter. The migration began
principally on 16 July, reached a mid-point on 23 July and was over on 20
August (Figure E.5.17). Seventy-five percent of the sockeye migrated over the

counters in an 11 day period between 19 July and 28 July. A total of 9,528
sockeye salmon were intercepted by fishwheels at Sunshine Station. Based on
fishwheel catch records {Table ED-2) the peak migration occurred between 18
July and 23 July. The highest catches (83.2%) were made on the east side of
the river.
A Talkeetna Station 3,464 sockeye salmon were counted. The majority of the
fish (54 percent) were enumerated on the west bank SSS counter. The
migration began on 23 July and was complete by 8 August. The mid-point
occurred on 31 July (Figure E.5.17). Seventy-five percent of the fish were
counted between 23 July and 6 August. Talkeetna Station fishwheels inter-
cepted 393 sockeye salmon. From a plot of the mean hourly fishwheel catch
(Figure ED-2) it appears that the peak of migration occurred between 27 July
and 1 August with sockeye showing no apparent bank preference.
Curry Station fishwheels intercepted a total of 470 sockeye salmon with the
majority (87.2%) being caught on the east side of the river. A plot of
fishwheel catch per hour indicates that migration began, reached a mid-point
and ended on 18 July, 5 August and 29 September respectively (figure ED-3).
Accuracy of population numbers generated by SSS is dependent upon site loca-
tion and species enumerated. Sonar counters do not enumerate every fish that
migrates upstream. They accurately count those which pass over the counting
plane or substrate of the counter but not those which migrate outside or-
offshore of the sonar substrate. Water depth, velocity, channel configu-
ration and location or absence of obstructions are variables which influence
E-5-39
where salmon migrate in the river at a particular time and location. Previous
investigations indicate that sockeye and pink salmon usually migrate near
shore within 60 feet or less of the bank (Tarbox, et. al., 1980). This
appears to be generally less true of other salmon species. However, at
Sunshine Station churn salmon were found to migrate closer inshore than sockeye
salmon at either Susitna, Yentna, or Sunshine stations (Figures E.5.18 and
E.5.19).
Sonar sector count data indicates that salmon, of all species, tend to display
greater bank preference the further they progress up the Susitna River
(Figures EE-l to EE-8). To illustrate this, 42.6 percent of the counts on the
east bank and 18.7 percent on the west bank at Susitna Station were registered
in offshore seCtors 6 to 12. At Talkeetna Station, 4.9 percent and 2.2
percent were recorded in the same sectors on the east and west bank respec-
tively, an indication that SSS counters become more effective counting all
salmon species in the upper reaches of the Susitna River. This increased
efficiency is probably associated with higher water velocities and greater
streambed gradient and channel consolidation in the upper Susitna River.
Sockeye salmon population estimates derived from fishwheel tagging operations
at Sunshine, Talkeetna and Curry stations indicate that 133,489, 4,809 and
2,804 sockeye salmon were present at each site respectively. The 95 percent
confidence limits on these estimates along with the components used to calcu-
late them are presented in Table E.5.10 and Appendix EJ.

These population estimates, as with others which will be presented in this
report, should not be considered to be the actual number of fish, in this case
sockeye salmon, that spawned upstream of the tagging location. The sockeye
estimates represent only the number that were present at the particular
tagging station. Other Susitna River investigations have revealed that all
adult salmon species mill to some degree in the mainstem and that it is not
uncommon to find adult salmon in the mainstem well upstream of their spawning
destination (Barrett, 1974 and Friese, 1975).
A further factor in considering the population estimates is tag loss and tag
induced mortalities. Both are capable of introducing positive bias to the
estimates (Everhart, et. al, 1975). Tag induced mortalities were not
considered significant due to minimal amount of time (10-20 seconds) required
to tag a fish, and the general vigorous condition of the fish caught in the
fishwheels. Tag loss was taken into consideration by adjusting the total
number of fish tagged by species according to percent occurrence of loose tags
found during foot surveys of clearwater spawning sloughs. This provided an
independent tag loss factor for Sunshine Station and Talkeetna Station which
was 7.5 percent and 3.4 percent respectively (Table E.5.11). The difference
in tag loss factor between the two stations can be attributed to the dif-
ference in tagging quality. At Sunshine Station the total number of fish
tagged was 24,159 compared to 2,176 at Talkeetna Station. The maximum number
of f~sh tagged in as single day at Sunshine Station was approximately 1,700
fish versus 250 fish at Talkeetna Station. The tag loss factor of Curry
Station tagged fish was presumed to be insignificant (less than one percent)
based on survey crews not finding any shed Petersen disc tags during spawning
E-5-44
ground surveys and the general difficulty encountered in removing these tags
from carcasses.

There is some discrepancy between populations estimates from sonar counts of
fish, versus estimates from the tag and recapture project (Table E.5.8). Both
estimates have deficiencies that must be recognized. It should not be assumed
that all fish pass over the SSS substrate. As previously discussed, the
sector distribution of salmon will vary, with site and species, with an unde-
termined number of salmon passing beyond the SSS counting substrate. A major
source of error present in SSS counts is related to the methods of apportion-
·ment and the bias inherent in those methods. Although all fishwheels used to
apportion the SSS counts were in close proximity to the counters it must be
recognized that fishwheels can be species select~ve. The apportioned sonar
counts would then reflect the selected catchability of the fishwheel. In
addition, SSS counters are adjusted for fish velocity and sensitivity, thereby
introducing an unknown variance component into the counts. Methods of cal-
culating confidence intervals around the population estimates are not
E-5-45
available for SSS counts because, at this time, it is not feasible to dupli-
cate a counting sample at one site at the same time, which does not allow for
a sampling estimate for the variance. It should be realized that SSS counts
are not absolute population numbers and at this time should be considered an
index of species abundance at a specific location. Tag and recapture methods
of estimating the population and the Petersen estimate in particular make six
assumptions which are listed in Began (1979}. It is realized that failure to
meet these assumptions will bias the population estimate and consequently the
confidence intervals. The following assumptions were made in estimating
population size: fishwheel capture of salmon was random with respect to the
population; there was no mortality as a result of the tagging process; there
was no differential mortality between tagged and untagged salmon; tagged
salmon mixed randomly within the population; and recovery of tagged salmon was
not influenced by the tag. The net result of tag loss, if not accounted for,
will result in an overestimation of the population and conversely if tagged
salmon are more readily visible than untagged salmon the resulting bias will
cause the population estimate to be low. In summary, it should be recognized
that both methods of enumerating salmon have potential drawbacks but at this
point they represent the state of the art in estimating population sizes in
glacial river systems. The discrepancies, where they exist, between Petersen
population estimates and SSS counts reflect the limitations inherent in both
techniques.
From the sonar data the migrational timing of sockeye salmon between the
mainstem sampling stations indicates that those passing Susitna Station bound
to the Yentna River made the six mile trip in one day or less, and of the fish
migrating past Susitna Station to Sunshine Station and destined to Talkeetna
E-5-46
Station had an average travel time of 8 days and 13 days respectively (Figure
E.5.20). This is an average travel rate of 6.8 miles/day between Susitna
Station and Sunshine Station and 4.6 miles/day between Sunshine Station and
Talkeetna Station. These migrational rates are considered valid if there is
no fundamental variation in timing between Susitna River sockeye salmon
stocks.
An i nsuffi ci ent number of tagged sockeye salmon recaptures were made at
Talkeetna Station to determine the average travel time rate between Sunshine
Station and Talkeetna Station. The data indicates that the minimum travel
time between these stations was three days or a travel speed of 7.7 miles/day
(Figure E.5.21). Tag recaptures of sockeye salmon at Curry Station indicates
a minimum travel time of five days from Sunshine Station to Curry Station and
one day from Talkeetna Station to Curry Station (Figure E.5.22). The average
migration time between Ta 1 keetna Station and Curry Station based on the tag
recapture data was approximately five days or a travel speed of approximately
3.5 miles/day.
Our investigations reveal that sockeye salmon generally reduced their travel
speed the farther they migrate upstream. A possible explanation for this
observation is that sockeye salmon display greater milling behavior as they
approach their natal stream therein reducing their net travel speed. This
behavior was indicated by a significant number of sockeye salmon recaptures at
Talkeetna Station that were intercepted more than 26 days earlier at Sunshine
Station located 23 miles downstream from Talkeetna Station (Figure E.5.21).

The sonar counts and fishwheel catches at Susitna Station, Yentna Station, and
Sunshine Station indicate a· strong preference by sockeye salmon to favor one
bank of the river depending on the location. Sockeye salmon were more
abundant on the west side of the Susitna River at Susitna Station and were
more numerous on the east bank at Sunshine Station. Yentna Station recorded
higher sonar counts and fishwheel catches on the south side of the river bank.
At Talkeetna Station, sockeye salmon utilized both sides of the river without
any notable preference. The fishwheel catches at Curry Station indicate that
sockeye are significantly more abundant on the east side of the river than on
the west side (Figure ED-3).
The migrational preference displayed by sockeye salmon for a particular side
of the river appears to be closely tied to site characteristics when proximity
or distance to a spawning area is not a factor. Agents influencing bank
preference in a specific reach of the river may be velocity, water depth and
channel configuration and presence or absence of navigational obstructions.
Evaluation of hourly passage rates indicate distinct behavior patterns of
sockeye salmon migrants at Susitna Station, Yentna Station and Sunshine
Station (Figure E.5.23). Higher than average passage rates occurred between
1900 hours and 0100 hours at Susitna Station and lower than average passage
between 0700 hours and 1100 hours. At Yentna Station sockeye salmon exhibited
greater upstream movement between 2300 hours and 0500 hours and displayed
lower than average upstream movement between 1100 hours and 1500 hours.
Sockeye salmon at Sunshine Station moved less between 0700 hours and 1100
hours than at any other time and displayed a higher than average preference
for movement between the hours of 1900 and 0100.

Figure E.5.23. Percent daily sonar counts of sockeye salmon by two hour blocks at Susitna Station,
Yentna Station, and Sunshine Station, Adult Anadromous Investigations, Su Hydro Studies, 1981.
Sockeye salmon age composition samples, collected in fishwheels, revealed that
the majority of the sockeye salmon at each of the sampling stations were age
s2 (Table. E.5.12}~ The next abundant were age 4 2 sockeye followed by age 6 2
sockeye. Five year old sockeye, 1976 brood year, comprised approximately 86
percent of the return at Susitna and Yentna stations, 73 and 72 percent
respectively at Sunshine and Talkeetna stations, and 70 percent of the sockeye
at Curry Station. Four year old sockeye, 1977 brood year, made up 8.5 percent
of the escapement return both at Susitna Station and Yentna Station and
represented 22.2 percent, 24.6 percent and 28.5 percent of the sodeye at
Sunshine, Talkeetna and Curry stations respectively. Approximately four
percent of the escapement return at each of the sampling stations were six
year old sockeye, 1975 brood year, with the exception of Curry Station which
had a 1.5 percent return of six year old sockeye salmon.
The apparent difference in age composition of sockeye salmon collected at the
lower sampling sites (Susitna and Yentna stations} as compared with the upper
sampling locations (Sunshine, Talkeetna and Curry stations} may be due to
differentia 1 freshwater surviva 1 or stock differences which caul d be deter-
mined conclusively through subsequent research efforts.
Table E.5.13 provides a summary of the sockeye salmon length data collected at
each of the sampling stations. Graphic representation of this information is
provided in Figures EF-1 through EF-5 and Figures EF-21 through EF-23. Five
year old male sockeye salmon averaged 590 mm, 605 mm, 604 mm, 571 mm, and

tively. The average length of five year old female sockeye salmon in the

The combined sockeye sa 1 man 1 engths of a 11 ages ranged from 230 mm to 675 mm
at Susitna Station, 310 mm to 684 mm at Yentna Station, 395 mm to 635 mm at

were larger than females in all age classes (Table E.5.13) but were more
numerous than female sockeye at only Talkeetna Station (1.2 to 1.0). At
Sunshine Station sex ratios indicate that male and female sockeye were equally
abundant (1.0 to 1.0). Males were less abundant than females at Susitna
Station (0.9 to 1.0), Talkeetna Station (0.6 to 1.0) and Curry Station (0.8 to
1.0).
5.2.1.2 Pink Salmon
Side Scan Sonar counters at Susitna Station enumerated 113,349 pink salmon; 88
percent on the east side and 12 percent on the west side of the Susitna River.
The pink salmon migration essentially began, reached a mid-point and termi-
nated on 10 July, 25 July and 21 August respectively (Figure E.5.24). Seventy-
five percent of the pink salmon migration passed Susitna Station in 15 days
between 15 July and 29 July. The fishwheels at Susitna Station caught a total
of 691 pink salmon. Of the 691 pinks caught, 57.5 percent were intercepted by
the west bank fishwheel and 42.5 percent intercepted by the east bank fish-
wheel. Figure ED-4 indicates the peak of migration occurred between 21 July
and 3 August.
At Yentna Station, 36,053 pink salmon were enumerated by sonar counters. The
south bank sonar counter recorded 82 percent of the counts while 18 percent
were registered by the north bank sonar counter. The beginning, mid-point and

end of the migration approximately occurred on 14 July, 27 July and 20 August
respectively (Figure E.5.24). Seventy-five percent of the p·ink salmon were
counted in 13 days between 21 July and 2 August. The two fishwheels located
at Yentna Station intercepted 2,729 pink salmon. Sixty-three and seven tenths
percent of the pink salmon were intercepted by the south bank fishwheel and
36.8 percent were caught by the north bank fishwheel. A graphic represen-
tation of the fishwheel catch per hour indicates that the peak of migration
occurred in the 17 day period between 21 July and.6 August (Figure ED-4).
At Sunshine Station SSS counters enumerated 72,945 pink sa 1 man. Eighty-four
and five-tenths percent of the counts were registered on the east side of the
river and 15.5 percent on the west side of the river. The migration
essentially began on 23 July, peaked on 1 August and terminated on 20 August
(Figure E. 5. 24). Seventy-five percent of the fish were counted in 13 days
from 28 July to 9 August. Four fishwheels were operated at Sunshine Station;
.
two on the west bank and two on the east bank of the Susitna River. A
combined total of 7,099 pink salmon were caught with the east bank fishwheels
intercepting 91.3 percent and the west bank fishwheels catching the remaining
8.7 percent. Figure ED-5, a plot of fishwheel catch per hour, shows the peak
of migration occurred between 29 July and 9 August.
Side scan sonar counters at Talkeetna Station enumerated 2,529 pink salmon.
Fifty-seven and three-tenths percent of the counts were recorded by the west
bank sonar and 42.7 percent by the east bank sonar. The migration principally
began on 27 July, reached a mid-point on 6 August and terminated on 20 August
(Figure E.5.24). Seventy-five percent of the escapement was intercepted
between 29 July and 9 August.
E-5-58
The four fishwheels operating at Talkeetna Station intercepted a total of 379
pink salmon. Fifty-nine point four percent were caught by the east bank
fishwheels and 40.6 percent were caught by the west bank fishwheels. Figure
ED-5 graphically illustrates that peak fishwheel catches of pink salmon
occurred between 1 August and 10 August.
The pink salmon migration at Curry station started on 31 July, reached a
midpoint on 8 August and terminated 19 August approximately (Figure ED-6).
Seventy-five percent of the escapement passed the site between 4 August and
19 August. The majority of the pink salmon fishwheel catch (69.9 percent) at
Curry Station was made on the east side of the river.
Population est·imates derived fronr tag and recapture data indicate that 53,101
pink salmon were present at Sunshine Station, 2,335 present at Talkeetna
Station and 1~146 present at Curry Station. The 95 percent confidence limits
along with the parameters used to calculate these estimates are presented in
Table E.5.10 and Appendix EJ.
The migrational rate based on plots of sonar and fishwheel catch data indicate
that pink _salmon took an average of three days to reach Yentna Station from
Susitna Station~ a distance of approximately six miles (Figures E.5.20 and
ED-5). This represents an average travel speed of about 2.0 miles per day.
These travel rates are valid only if there is no fundamental variation in
migrational timing between Susitna River pink salmon stocks.
Pink salmon averaged about nine days of travel time between Susitna Station
and Sunshine Station (Figure E.5.20). This represents an average travel rate
E-5-59
of 6.0 miles/day. Tr~vel time between Susitna Station and Talkeetna Station
was approximately 12 days or a travel speed of 6.4 miles/day.
Tag and recapture data on pink salmon indicate that travel time between
Sunshine Station and Talkeetna Station ranged from two to 30 days (Figure
E.5.21). Pink salmon averaged three days of travel time or six miles/day
between Talkeetna Station and Curry Station with a range of one to 13 days
(Figure E.5.22).
Table E.5.14 provides a summary of the pink salmon length data collected at
each of the mainstem sampling stations. Graphic representation of this data
is provided in Figures EF-6 through EF-10 and Figure EF-24. The average
length of male pink salmon was 444 mm at Susitna Station, 478 mm at Yentna
Station, 445 mm at Sunshine Station and 432 mm at Curry Station. In compari-
son females averaged 433 mm, 471 mm, 449 mm, 434 mm, and 432 mm in the same
order by station. The data indicates that pink salmon stocks in the Yentna
River subdrainage were larger than the pink salmon stocks utilizing the
Susitna River upstream of the Yentna River confluence (Figure EF-24).
Table E~5.14 also summarizes the sex composition of pink salmon sampled from
fishwheel catches at each of the stations. Male pink salmon were more
abundant than females at all sampling stations except at Talkeetna Station
where females were 20 percent more numerous (1:1.2) than males.

5.2.1.3 Chum Salmon
A total of 46,461 chum salmon were enumerated at Susitna Station with SSS
counters. The majority (91.1%) of the fish were enumerated on the east side
of the river and the balance (8.9%) on the west side. The migration arrived
at Susitna Station, on 10 July, reached a mid-point on 27 July and ended on 25
August (Figure E.5.25). Seventy-five percent of the escapement was counted
between 15 July and 6 August. A total of 250 chum salmon were caught in the
fishwheels operated at Susitna Station. The peak migration, as indicated by a
plot of the mean hourly fishwheel catch (Figure ED-7), occurred between 3
August and 7 August with the majority of fishwheel interceptions occurring
along the east bank.
The Yentna Station SSS counters enumerated 19,765 chum salmon. Sixty-four and
four-tenths percent of the counts were recorded by the south bank sonar and
35.6 percent by the north bank sonar. The chum salmon migration essenti-ally
began at Yentna Station on 13 July, reached a mid-point on 29 July and
terminated on 24 August (Figure E.5.25). Seventy-five percent of the fish
were counted in a 29 day period between 18 July and 15 August. Fishwheels
operated at Yentna Station caught a tota1 of 1,415 chum salmon. Chum salmon
passage at Yentna Station reached a peak between 20 July and 23 July as
indicated by fishwheel catch data (Figure ED-7). The north and south bank
fishwheels, respectively, caught 66.3 percent and 33.7 percent of the chum
salmon.
Side scan sonar counters at Sunshine Station counted 59,630 chum salmon. The
east bank counter recorded 77.9 percent of counts and the remainder, 22.1

percent, were registered on the west bank counter. The chum salmon migration
began on 22 July, reached a mid-point on 6 August and terminated on 6
September, approximately (Figure E.5.25). Seventy-five percent of the fish
were counted in a 29 day period between 27 July and 24 August. A total of
9,168 chum salmon were caught in the four fishwheels at Sunshine Station. The
peak of chum salmon migration at Sunshine Station, as indicated by daily
fishwheel catches, occurred between 17 August and 19 August (Figure ED-8).
The east bank fishwheels intercepted more chum salmon than the west bank
wheels by a ratio of 9.1:1.
A total of 10,036 chum salmon were counted at Talkeetna Station. The west
bank SSS counted 59.6 percent of the chum salmon and 40.4 percent ~'/ere
enumerated by the east bank SSS. The migration approximately began on 28
July, reached a mid-point on 8 August and ended on 29 August (Figure E.5.25).
Seventy-five percent of the escapement was counted in a 32 day period between
30 July and 30 August. A total of 1,285 chum salmon were intercepted by the
fishwheels at Talkeetna Station. Seventy-five percent were caught between 4
August and 7 September with 48.7 percent and 51.3 percent of the total catch
intercepted in the east and west bank fishwheels respectively (Figure ED-8).
Fishwheel catches at Curry Station indicate that the migration essentially
began on 29 July, reached a mid-point on 16 August and terminated on 2
September (Figure ED-9). The majority (89.6%). of the catch was made on the
east side of the river.
Tag and recapture data indicates that 262,851 chum saimon were present at
Sunshine Station, 20,385 at Talkeetna Station and 13,068 at Curry Station.
E-5-64
The 95 percent confidence limits and variables used to calculate the estimates
are presented in Table E.5.10 and Appendix EJ.
Chum salmon averaged four days of travel time between Susitna Station and
Yentna Station for a travel speed of 1.5 miles/day. The average travel time
between Susitna Station and Sunshine Station was 10 days which computes to a
travel speed of 5.4 miles/day. The migration period between Susitna Station
and Talkeetna Station averaged 14 days or 5.5 miles/day. The migration timing
and travel rates presented· above are considered valid if there is no funda-
mental variation in timing between Susitna River chum salmon stocks.
Chum salmon tagged at Sunshine Station took between two and nine days to reach
Talkeetna Station (Figure E.5.21). Between Talkeetna Station and Curry
Station the number of travel days ranged from one to 24 days with an average
travel time of approximately 4.5 days and a mean travel speed of 3.8 miles/day
(Figure E.5.22).
Eva 1 uati on of the hourly passage rate of chum salmon at Sunshine Station
suggests a distinct behavior pattern with a high percentage of the fish
passing the counters between 2100 hours and 0100 hours and between 0300 hours
and 0500 hours (Figure E.5.26). The lowest hourly passage rate occurred
between 0700 hours and 1100 hours. East bank SSS sector counts at Sunshine
Station indicate that chum salmon displayed a strong migrational preference
for near-shore travel. More than 60 percent of the chum salmon were counted
in the first sonar sector and 30 percent in the second sector (Figure E.5.19).
Comparison data is not available for the other stations due to the absence of
discrete periods when chum salmon comprised 90 percent or more of the counts.

Adult Anadromous Investigations, Su Hydro Studies, 1981.
Table E.5.15 outlines the age structure of the chum salmon sampled at each of
the stations. Age 41 chum salmon from the 1977 brood year dominated the catch
at each site comprising an average of 86 percent of the fish. Next abundant
were age 51 fish followed by age 31 fish which made up 10 percent and four
percent of the age samples respectively. The most notable difference in age
class structure was among the chum salmon sampled at Curry Station which were
14.1 percent and 1.9 percent age 51 and 31 fish respectively. This is a
considerable variation from the above cited averages for the combined
stations.
Presented in Table E.5.16 is a summary of chum salmon length data collected at
each sampling location. These data are also graphically displayed in Figures
EF-11 through EF-15 and Figures EF-25 through EF-27. Chum salmon of all age
classes at Susitna Station ranged in size from 445 mm to 658 mm, at Yentna
Station from 436 mm to 697 mm, at Sunshine Station from 455 mm to 718 mm, at
Talkeetna Station from 480 mm to 720 mm and at Curry Station from 440 mm to
680 mm. Four year old male chum salmon had an average length of 593 mm,
601 mm, 624 mm, 586 mm, and 593 mm at Susitna, Yentna, Sunshine, Talkeetna and
Curry stations respectively. Female chum salmon of the same age in the same
station order as defined above had an average length of 581 rnm, 585 mm,
588 mm, 578 mm, and 614 mm respectively.
Table E.5.16 also provides a comparison of sex ratios between age classes by
sampling location. Combined age class sex ratios indicate that male chum
salmon were less abundant than females at Susitna Station (1:1.6) and· Sunshine

5.2.1.4 Coho Salmon
A total of 33,470 coho salmon were enumerated across the SSS counters at
Susitna Station. Seventy percent were registered by the east bank SSS and the
balance by the west bank SSS. The migration began, reached a mid-point and
ended on 20 July, 28 July and the 25 August respectively (Figure E.5.27).
Approximately 75 percent of the fish passed in 25 days between 23 July and 16
August. The fishwheels at Susitna Station caught a total of 329 coho salmon.
Coho salmon showed a strong bank preference with 76.3 percent moving up the
west bank and 23.7 percent migrating along the east bank. A plot of fishwheel
catch per hour indicates the peak of migration occurred between 25 July and 30
July (Figure ED-10).
The Yentna Station SSS counters enumerated a total of 17,017 coho salmon. The
south bank counter registered 83.6 percent of the count and the north bank
counter registered 16.4 percent of the count. The migration principally began
on 22 July, reached a mid-point on 31 July and ended on 20 August (Figure
E.5.27). Seventy five percent of the fish passed between 23 July and 16
August. A total of 1,122 coho were intercepted by Yentna Station fishwheels
with 75:7 percent and 24.3 percent of the catch caught along the south and
north bank respectively. The peak of migration, as shown by a plot of
fishwheel catch per hour, occurred between 23 July and 6 August (Figure
ED-10).

and Talkeetna Stations,
Side Scan Sonar counters at Sunshine Station counted a total of 22,793 coho
salmon. Sixty-six and six-tenths percent of the fish passed over the west
bank sonar and the remaining 33.4 percent over the east bank sonar. The
migration principally began at Sunshine Station on 29 July, reached a
mid-point on 18 August and terminated on 5 September, approximately (Figure
E.5.27}. Seventy-five percent of the migration was counted in the 21 days
between 4 August and 24 August. Sunshine Station fishwheels intercepted 2,928
coho salmon. There was no apparent preference between river banks with 51.6
percent and 48.4 percent of the coho salmon migrating along the east and west
bank respectively. A plot of the fishwheel catch per hour graphically illus-
trates that coho salmon passage peaked between 18 August and 25 August (Figure
ED-11).
The SSS counters at Talkeetna Station recorded a total of 3,522 coho salmon .
. The west bank sonar enumerated 62 percent of the fish and the east bank sonar,
38 percent. The migration approximately began, reached a mid-point, and ended
on 30 July, 24 August and 11 September respectively (Figure E.5.27).
Seventy-five percent of the coho sa 1 man were counted in the 22 days between
11 August and 1 Septe~ber. The four fishwheels operated at Talkeetna Station
intercepted a total of 533 coho salmon with 59.5 percent being caught in the
two west bank fishwheels. Fishwheel catch per hour plots indicate that the
peak of migration occurred between 19 August and 30 August (Figure ED-11).
Curry Station fishwheel catches indicate that the coho salmon migration began,
reached a mid-point and ended on 5 August, 22 August and 4 September respec-
tively (Figure ED-12). The majority (64.8%) of the fish at Curry Station were
intercepted on the east side of the river.
E-5-72
Population estimates derived from tagging and recapture operations indicate
that 19,841 coho salmon were present at Sunshine Station, 3,306 present at
Ta ·1 keetna Station and 1,041 presenf at Curry Station. The parameters used to
calculate the estimates along with the 95 percent confidence limits are
presented in Table E.5.10 and Appendix EJ.
The average migrational travel time of coho salmon between Susitna Station and
Yentna Station was two days which is an upstream travel speed of 3.0 miles/day
(Figure E.5.20). An average of fourteen days were required to reach Sunshine
Station from Susitna Station. The total travel time from Susitna Station
beyond Sunshine Station to Talkeetna Station was approximately 24 days. This
represents a travel speed of 3.9 and 3.2 miles/day respectively. These
migration rates are based on the assumption that there is no fundamental
variation in timing between Susitna River coho salmon stocks.
Tag recaptures of marked coho salmon from Talkeetna Station at Curry Station
indicate that coho salmon migrated between these stations in two to 15 days
(Figure E.5.22}. The average travel time was 4.5 days or a travel speed of
3.8 miles/day.
Table E.5.17 summarizes the coho salmon age composition by sampling location.
The data indicates that the majority of the fish were age 43 from the 1977
bro.od year followed by age 32 from the 1978 brood year. Less than 10 percent
of the coho escapement was comprised of other age classes.

A summary of coho salmon lengths collected by sampling station is presented in
Table E.5.18. This data is also graphically displayed in Figures EF-16
through EF-20 and Figures EF-28 through EF-30. Lengths ranged from 216 mm to
645 mm at. Susitna Station, 365 mm to' 635 mm at Yentna Station, 325 mm to
680 mm at Sunshine Station, 330 mm to 650 mm at Talkeetna Station and 370 mm
to 605 mm at Curry Station. The average lengths of four year old male coho
salmon were 519 mm, 541 mm, 541 mm, 534 mm, and 519 mm at Susitna, Yentna,
Sunshine, Talkeetna and Curry stations respectively. Four year old female
coho salmon in the station order as defined above averaged 530 mm, 540 mm,
542 mm, 538 mm and 541 mm.
The male female ratios of coho salmon for all age classes combined was 1.2:1
at Susitna Station, 1.1:1 at Yentna Station, 0.8:1 at Sunshine Station, 0.7:1
at Talkeetna Station and 0.5:1 at Curry Station (Table 5.5.18).
5.2.2 Survey Investigations
5.2.2.1 Mainstem Surveys
Presented in Table EG-1 is a list of the locations and catch results for
approximately 310 sites sampled with gill nets and electroshocking gear on
Susitna River mainstem. Twelve mainstem spawning locations were identified
(Table E.5.19). Chum salmon were found spawning at 10 of 12 sites. Coho
salmon were found spawning alone at one site and both coho and chum salmon
were recorded sharing spawning sites in two mainstem areas. One of the 12
spawning areas was located at RM 100.5. This site was determined on the basis

of visual sightings of redds on 24 September and egg deposition sampling on
30 October. Salmon eggs were found in subsurface gravels at the same site,
but it was not possible to confirm which species spawned there. Maps of each
of the 12 spawning areas are presented in Figures EH-1 through EH-12. These
spawning areas are located between RM 68.3 and RM 135.2.
Echo recorders did not prove effective in identifying mainstem spawning areas.
They were tested in mainstem sloughs and although adult fish were located
through vertical scanning, interpretation of recording printouts on the
mainstem Susitna River was difficult because debris echoes had a similar
appearance to fish and turbulence produced false recordings. Further
compounding the problem was the inability to operate echo recorders against
the force of the river current. The gunne 1 mounted transducer brackets
commonly bent and become inoperative particularly in areas where water
velocity was greater than three feet per second.
Drift gill nets were effective in locating five of the 12 mainstem spawning
sites previously referenced. They were not however, considered an efficient
means of sampling due to variable water depths encountered. Many areas were
severa 1 meters deeper than the 1. 5 m depth limit of the nets. In sha 11 ower
areas, debris caused nets to be torn and resulted in several hours of mending
for each hour fished.
Electroshocking gear was not available to survey crews operating above RM 61
until 21 September. Although only one mainstem spawning site was found with
this gear type, it worked efficiently in all areas of the river where used and
E-5-79
was considered superior to drift gill nets and depth recorders. It is
probable that additional spawning areas would have been located had
4lectroshocking gear been used earlier in the season, particularly in late
August and early September.
Results of set netting in the area immediately below Devil Canyon between RM
150.1 and 150.4 (Figure E.5.28) are presented in Table E.5.20. The data
confirms that sockeye, chum and coho salmon use the Susitna River mainstem
above Portage Creek for migration purposes. A catch comprised of sockeye,
chum and coho salmon was made on 26 August at RM 150.2 and a single coho
salmon was captured on 2 September at RM 150.4. All gill netted fish were in
pre-spawning condition. The single coho salmon caught on 26 August had been
tagged .earlier at Talkeetna Station on 7 August. Set netting conducted
between 29 July and 5 August and also from 2 September to 19 September did
not produce fish. No set netting was performed between 6 August and 25 August
due to high water conditions.
5.2.2.2 Escapement Surveys
Escapement surveys were conducted on 32 sloughs and 15 tributary streams in
the Susitna River reach between the Chulitna River and Devil Canyon· (Figure
E.5.29). Eight new sloughs and streams were located which supported salmon
spawning. These sloughs are referenced as Moose (RM 123.5), A1 (RM 124.6), 98
(RM 124.2) and 21A (RM 145.5). The new streams are Gash Creek (RM 111.6),
Lower McKenzie Creek (RM 116.2), 5th July Creek (RM 123.7) and Jack Long Creek
(RM 144.5). The location of these streams and sloughs relative to the Susitna
River mainstem are defined in Figure E.5.29.

Adult sockeye salmon were observed in Sloughs 38, 3A, 6A, SA, 9, 9A, 98, 11,
17, 19, 20 and 21 and in Lower McKenzie Creek (Tables EJ-1 through EJ-2).
Peak spawning occurred during the 1 ast week of August and the first three
weeks of September (Figures E.5.30 through E.5.32). Sockeye salmon were most
numerous in Slough SA, 98 and 11 where peak spawning ground counts were 177,
S1, and S93 sockeye salmon respectively.
Pink salmon were found in Sloughs 3A, S and A, and in Whiskers Creek, Chase
Creek, Lane Creek, Fourth July Creek, 5th July Creek, Skull Creek, Sherman
Creek, Indian River and Jack Long Creek (Tables EJ-1 and EJ-2). The highest
peak spawning count within an index area was in Lane Creek where 291 fish were
recorded. Peak spawning occurred in a 10 day period from 19 August to 2S
August (Figure E.5.33). The stream survey counts are index counts and do not
reflect total number of spawning fish present in the stream surveyed.
Chum salmon were present in Sloughs 1, 2, 6A, S, SB, Moose, A1 , A, SA, 9, 98,
9A, 11, 13, 15, 17, 19, 20, 21, and 21A (Table EJ-1). They were also found
within the survey reaches of Whiskers Creek, Chase Creek, Lane Creek, Lower
McKenzie Creek, Skull Creek, Sherma.n Creek, Fourth July Creek and Indian River
(Table EJ-2). The peak of spawning activity in the sloughs occurred during
the 1 ast two weeks of August and the first two weeks of September (Figures
E.5.30 through E.5.32).· The highest counts were recorded in Sloughs S, 8A, 9,
11 and 21 where 302, 620, 260, 411 and 274 chum salmon, respectively, were
found spawning (Figure E.5.34). Based on the stream survey data the peak
spawning period in streams was approximately one week earlier than that

observed in slough spawning areas. The highest peak count in an index area
was registered on Lane Creek where 76 chum sa 1 man were counted on 23 August
( F i g u re E. 5 . 3 3 ) .
Coho salmon were not found in any of the sloughs surveyed but were observed in
Whiskers Creek, Chase Creek, Lane Creek, Gash Creek, Lower McKenzie Creek,
Fourth July Creek, Indian River and Portage Creek (Tables EJ-1 and EJ-2}. The
highest densities of coho salmon, based on peak index counts, were in Whiskers
Creek, Chase Creek, Gash Creek and Indian River where 70, 80, 141, and 85 coho
salmon respectively were recorded spawning in a single survey. The survey
data indicates that the spawning" peak probably occurred in the second and
third week of September.
5.2.3 Radio Telemetry Investigations
5.2.3.1 Chum Salmon
Eleven chum salmon were radio tagged between 30 July and 12 August and their
movements monitored during 30 and 31 July and August, 1981 (Table E.5.21).
Ten of the 11 fish were tagged between 6 and 12 August. Seven fish were
tagged at Curry Station and four were tagged at Talkeetna Station (Figure
E.5.35). Five were females and six were males (Table E.5.21).
Eight of the radi a tagged chum sa 1 man moved upstream from their respective
tagging locations. Two others moved downstream and one remained within ±0.2
river miles of its tagging location (Figure E.5.36).

Radio tagged chum salmon that moved upstream after tagging exhibited two types
of movement. Upstream movement, with cessations of less than 72 hours was
termed 11 direct movement 11
• Upstream movement with cessations in excess of 72
hours, was termed, 11 indirect movement 11
•
Direct movement was exhibited by chum salmon bearing transmitters numbered
650-3, 680-2 and 710-2 (Figure E.5.36). Indirect movement was displayed by
fish bearing transmitters numbered 660-1, 680-3 and 720-1. Fish bearing
transmitters numbered 680-3 and 720-1 remained in the Susitna River within 0.3
miles of the mouth of Fourth July Creek (RM 131.0) for three and 11 days
respectively, and fish carrying transmitter number 660-1 remained at the mouth
of Lane Creek (RM 113.6) for at least six days.
The five remaining radio tagged chum salmon exhibited other movements (Figure
E.5.36). Two individuals bearing transmitters numbered 700-1 and 700-3 moved
downriver, the first individual entered a slough at RM 96.9 whereas the other
chum salmon ascended the C~ulitna River. Fish bearing transmitter number
670-2 remained within 0.2 miles of its tagging location at RM 119.5. A chum
salmon carrying transmitter number 730-2 was last detected at RM 127.0.
A female chum salmon regurgitated transmitter number 740-1 at RM 121.1 several
days after being tagged on 11 August at Curry Station (RM 120). This fish was
observed later spawning without its radio transmitter in Slough 11 (RM 135.3)
on 29 August.
Determination of chum salmon upstream, migration rates was influenced by the
time separating consecutive tracking efforts. Eighteen percent of the
E-5-96
detections, e.g. location of fish•s positions in the river, were made within a
peri ad of 24 hours whi 1 e 43 percent were made between 24 and 48 hours.
Because of these relatively long intervals and because exact arrival times at
upstream locations are unknown, the movement rates, with few exceptions, are
expressed as 11 greater than or equal to 11 (>) speeds.
The .fastest documented rate of chum salmon migration was 1.0 miles per hour
(mph). Fish bearing transmitter number 710-2 moved 1.9 miles
upstream within 1.9 hours after release (Table E.5.22). Perhaps more typical
of sustained rapid movement is the subsequent movement of this fish when it
traveled 22.2 miles within 32.5 hours for a rate ~ 0.68 mph or 16.4 miles/day.
In contrast, fish bearing transmitter number 650-3 moved 5.1 miles within 39
hours for a rate~ 0.13 mph or 3.1 miles/day.
Rates of movement of two radio tagged chum sa 1 man which migrated 11 di rectly 11
upstream suggest that radio tag implantation did not interfere with their
upstream migration as their rates of movement were similar to that exhibited
by chum salmon tagged with Flay tags at Talkeetna Station (RM 103). Two chum
·salmon radio tagged at Talkeetna Station on 6 August reached Curry Station (RM
120) within two days. Fish bearing transmitter number 730-2 was detected 0.~
miles upriver of Curry Station 48 hours after being radio tagged at Talkeetna
Station. Another chum salmon, bearing transmitter number 710-2, was located
9.2 miles upriver of Curry Station, 51 hours· following transmitter
implantation at Talkeetna Station. One hundred six chum salmon tagged with
Flay tags at Talkeetna Station were recaptured by fishwheels at Curry Station
16.5 river miles upriver. Twenty of the 106 fish were recaptured after one

day of release, 42 after two days, 53 after three days, 74 after four days and
86 after five days. The number of recaptures progressively decreased each day
until 106 recaptures were recorded.
The influence of flow on the movements of radio tagged chum sa 1 man in the
Susitna River is not apparent due to the small number of chum salmon tagged,
and the variable flow conditions encountered by these fish (Figure E.5.36).
The primary destinations of radio tagged chum salmon were Susitna River
sloughs, clear water tributaries and the confluence zones of tributary streams
(Figure E.5.36). The four fish bearing transmitter numbers 660-1, 710-2,
740-1 and 700-1 entered Susitna River sloughs 21 (RM 142.0), 11 (Rm 135.3),
Moose (RM 123.5) and an unnamed slough (RM 96.9) respectively. The three fish
bearing transmitter numbers 650-3, 680-2 and 680-3 entered the Indian River
(RM 138.6). One fish bearing transmitter number 720-1 entered Sherman Creek
(RM 130.8) before returning to the mainstem Susitna River where it held within
0.3 miles of the Fourth July Creek confluence zone (RM 131.0). One fish
bearing transmitter number 670-2 stayed in the mainstem Susitna River at RM
119.6. One fish bearing transmitter number 700-3 swam down the Susitna River
and entered the Chulitna River (RM 98.6). Fish bearing transmitter 730-2 was
last detected at RM 127.0 in the Susitna River.
Radio tagged chum salmon entered spawning areas between 8 August and
23 August. Fish bearing transmitter number 710-2 entered Slough 11 (RM 135.5)
about 13 August and was observed building a redd on 21 August. It had
completed spawning by 2 September when it was captured and n~cropsied. Fish
bearing transmitter number 740-1 entered Moose Slough (RM 123.5) between
E-5-99
13 August and 18 August. On 29 August it was observed over a redd and netted.
A brief external examination revealed that most eggs were still present in the
body cavity although the transmitter was absent. The transmitter had been
found earlier at RM 121.1, the site of apparent regurgitation. On 4 September
the carcass of this fish was found in Moose Slough (RM 123.5). A necropsy
indicated the fish had spawned, as evidenced by the lack of eggs in the
coelom.
Individual movements of radio tagged chum salmon are further described in
Appendix EK.
5.2.3.2 Coho Salmon
Ten coho salmon were radio tagged from 31 August through 4 September. Four
were tagged at Curry Station and six at Talkeetna Station (Table E.5.23).
Eight bore wire reinforced radio transmitters whereas two carried non-
reinforced transmitters (660-2 and 680-1).
The radio tagged coho salmon from Talkeetna Station and one from Curry Station
moved downriver upon release. Three of the four fish entered tributaries
downstream of RM 102.8 of the Susitna River (Figure E.5.37). Fish supporting
transmitter number 700-2 entered the Chulitna River (RM 98.6) and moved
upstream to RM 31.9. Another individual bearing transmitter number 710-1
entered the Talkeetna River and ascended Chunilna Creek (RM 5.9). Fish
carrying transmitter number 710-3 moved downstream in the Susitna River to RM
88.0 and ascended Birch Creek (RM 88.0) to Fish Lake and. spawned in an inlet
stream. The fourth fish, supporting transmitter number 720-2, was apparently

and September, 1981, Adult Anadromous Investigations,

adversely influenced by transmitter implantation as evidenced by observations
of the fish while it occupied Chase Creek (RM 106.9).
Length of stay of the above three radio tagged coho salmon in the Susitna
River upstream of RM 100.1 was variable; fish bearing transmitter number 700-2
moved downstream to Whiskers Creek (RM 101.2) and remained there for several
days prior to moving further downstream and ascending the Chulitna River (RM
98.6). The other two fish supporting transmitter numbers 710-1 and 710-3
moved downriver after tagging.
Two coho salmon tagged at Talkeetna Station bearing transmitter numbers 650-2
and 730-3 exhibited upstream movement after tagging. The fish with trans-
mitter number 650-2 entered Indian River (RM 138.6) eight days after tagging
and the fish with transmitter number 730-3 remained at the mouth of Fourth
July Creek (RM 131.0) ,for several weeks before moving up the creek. Both fish
were implanted with transmitters having modified antennas.
Four coho salmon tagged at Curry Station exhibited multi-directional movements
in the Susitna River (Figure E.5.37). Two fish carrying transmitter numbers
650-1 and 660-2, entered and spawned in Gash Creek (RM 111.6). Fish bearing
transmitter number 650-1 moved downstream and remained in the Talkeetna River
(RM 97 .0) prior to moving up the Susitna River and entering Gash Creek (RM
111.6) whereas fish bearing transmitter number 660-2 moved upriver to RM 141.1
then descended to and entered Gash Creek (RM 111.6). , Another coho salmon
supporting transmitter number 680-1 moved downriver to RM 101.5 and held there
for several days before migrating upstream to RM 109.8 where transmitter
E-5-103
reception was lost. The other fish bearing transmitter number 720-3, moved
upriver to RM 131.0, before descending to and remaining at RM 117.8, near the
mouth of Little Portage Creek through early October. This fish apparently did
not spawn.
Movements of coho salmon apparently were not influenced by flow conditions
within the Susitna River (Figure E.5.37).
Adult, r~dio tagged coho salmon moved upstream at various rates, although the
relatively long periods of time separating some successive fish positions
probably under-estimated the upstream migration rates {Tab 1 e E. 5. 24). The
fastest upstream migration rates, 0.67 to 1.00 mph, generally occurred at
intervals of less than five hours. However some coho salmon moved upstream to
0.23 to 0.60 mph during longer intervals of 20 to 60.8 hours. Consequently,
all upstream migration rates are expressed as equal to or exceeding{~),
except for those successive fish positions separated by less than five hours.
Behavior of adult radio tagged coho salmon near the mouths of Susitna River
tributaries was variable {Figure E.5.37). Some individuals, such as fish
bearing transmitter numbers 650-1 and 650-2, occupied positions in the
mainstem Susitna River at or within 0.1 mile of the mouth of Gash Creek (RM
111.6) for several days prior to entering that tributary. Other coho salmon
such as those carrying transmitter numbers 650-2 and 720-3, remained in the
Susitna River within 0.1 mile of the mouth of Fourth July Creek (RM 131.0) and
Little Portage Creek {RM 117.8), respectively, for two or more weeks. Fish
bearing transmitter number 650-2 entered Fourth July Creek after holding at

its mouth for about two weeks whereas fish bearing transmitter number 720-2
remained near Little Portage Creek (RM 117.8) for about three weeks and
apparently did not ascend that stream.
Three radio tagged female coho salmon spawned in streams connected to lakes as
evidenced by their spawned out condition upon necropsy. However, actual
spawning activity was not observed. Two spawned out individuals supporting
transmitter numbers 650-1 and 660-2 were detected in Gash Creek (RM 111.6);
one carried a wire modified transmitter whereas the other supported the
heat-to-shrink material modified transmitter. The other fish bearing
transmitter number 710-3 spawned in Cabin Creek, a tributary of Fish Lake ('RI"1
4.7 Birch Creek) and bore a wire modified transmitter.
The above three individuals spawned within one week after entering Susitna
River tributaries in September. A female fish bearing transmitter number
710-3 was found spawned out and dead less than one week after entering Cabin
Creek (RM 4.7 Birch Creek) in September. Two fish bearing transmitter numbers
660-2 and 650-1, were found in a spawned-out condition within seven days after
entering Gash Creek (RM 111.6) on about 21 and 22 September.
A female· coho salmon bearing transmitter number 650-2 displayed a similar
pattern of tributary occupancy in Fourth July Creek (RM 131.0). This
individual entered the stream on 20 September after remaining in the Susitna
River near the mouth of this stream for about two weeks. On 23 September it
was detected in the Susitna River at RM 130.0. The spawning status of this
fish was not determined.

Chum Salmon, Radio Transmitter #650-3
This male chum salmon was radio tagged at river mile (RM) 119.5 on
7 August (Figure EK-1). Within 33.5 hours of tagging the chum salmon
moved 14.3 miles upstream, at a rate greater than or equal to
(~) 0.43 miles per hour (mph). During the next 39 hours the fish moved
an additional 5.1 miles upstream to a position 0.3 miles above the
Indian River confluence (RM 138.6). Sometime during the following three
days the fish entered the Indian River (RM 138.6) where it was found
1. 3 miles above the confluence on 13. August. It remaineA in the Ind ·an
River between RM 2.1 and 0.6 for the remainder of the season, fifteen
tracking flights.
Chum Salmon, Radio Transmitter #660-1
On 10 August this male chum salmon was radio tagged at RM 102.9
(Figure EK-2). Within several hours this fish moved 1.9 miles downriver.
Nineteen and six tenths (19.6) hours later, however, it had moved
8 miles upstream. This upstream movement was ~ 0.41 mph. During the
next 'eight hours the fish~ _moved downstream about 0. 8 mile. Within
fifteen hours it had resumed upstream migration and was detected 5.4
miles upstream, at the mouth of Lane Creek (RM 113.6). The salmon
remained there for at least three days and then began moving upstream.

Slough 21 was surveyed by foot. The functional radio transmitter was
found about 20 feet from the water amongst the remains of the fish
carcass. This fish was apparently captured by a predator.
Chum Salmon, Radio Transmitter #670-2
This female chum salmon was radio tagged on 12 August at RM 119.5
(Figure EK-3). It displayed very little movement following release.
Within 2.4 hours it moved 0.2 miles upstream. Almost 21 hours later it
was found 0.8 miles upstream at RM 120.5. Two days later it had dropped
to RM 119.8, a position only 0.3 miles upstream from its release site.
During the remainder of the season and a total of 27 more tracking fixe.s
the fish stayed between RM 119.9 and 119.6. During this time it periodically
moved between the east and west banks. Several attempts to recover the
fish failed.
Chum Salmon, Radio Transmitter #680-2
On 6 August this male chum salmon was radio tagged at RM 120.7
(Figure EK-4). Immediately upon release this chum salmon moved downriver;
within 45 minutes it was 0.1 mile downstream. Less than 2 days later
(42.5 hours), however, it had migrated 21.3 miles upstream to a position
3.3 miles up the Indian River (RM 138.6). Movement rate to this location
was > 0.50 mph. For the next ten days the fish was found between Indian
River mile 3.3 and 2.4. On 23 August it had moved downstream to Indian
RM 1.7. For the remainder of the season it was found between RM 1.9
and 1.1 of the Indian River.

Chum Salmon, Radio Transmitter #680-3
On 9 August this male chum salmon was radio tagged at RM 119. 5
(Figure EK-5). Within 17.3 hours following transmitter insertion,
the fish moved 4.2 miles upstream to RM 123.7 for a movement rate
I ~· 0.24 mph. For at least the next 30 hours it held position! at RM 123.7.
On 13 August it was found approximately 1.3 miles upriver of Fourth July
Creek (RM 131.0) at RM 132.3 along the west shore of the Susitna River.
Movement to this location was ~ 0.18 mph. It then moved downstream to
within 0.05 miles of the mouth of Fourth July Creek (RM 131.0) and
remained there about six days. Sometime after 1100 hours on 21 August
the fish began moving upstream. On 23 August it was located in the
Indian River about one half mile above the confluence with the Susitna
River (RM 138.6). Movement rate to this location was~ O.l72mph. The
fish stayed in the Indian River approximately one week and was consistently
detected within the lower one-half mile of this stream. It re-entered
the Susitna River after 1233 hours on 28 August and was found at RM
132.5 on 30 August. During the remainder of the season the fish did not
move from this position.
Chum Salmon, Radio Transmitter #700-1
This female chum salmon was radio tagged on 12 August at RM 119.5
(Figure EK-6). Within 3 hours of release this fish moved 0.2 miles
below the release site. Twenty-one and one half (21.5) hours later it
had moved 0. 5 miles upstream. During the next eight days and four
tracking attempts it was undetected. On 23 August it was discovered at

RM 98.6 in the Three Rivers Area {TRA) near the Chulitna-Susitna River
confluence, about 20 miles downriver from its last known position. By
31 August the fish had moved into Slough S-14 {RM 96.9) on the west side
of the Chulitna-Susitna confluence area. On 8 September the transmitter
was recovered from the carcass along the bank of Slough S-14, located at
RM 96. 9. Spawning condition could not be determine¢!. due to the advanced
state of carcass decomposition.
Chum .Salmon,·. Radio Transmitter #700-3
On 3 July this female chum salmon was radio tagged at RM 102.9
(Figure EK-7). After tagging this fish moved downstream and remained in
the Susitna River at RM 99.5, just above its confluence with the Chulitna
River, until 6 August, a period of about one week. It then moved into
the Chulitna River and was found on 8 August, 12 miles upriver of the
TRA. Movement during this time was > 0.24 mph. Ten days later the fish
was found at RM 16.1 of the Chulitna River. During the remainder of the
season this fish could not be found, probably due to transmitter failure;
erratic transmitter. signa!;s were.:cdetected during the 6 and 7 August
aerial tracking flights.
Chum Salmon, Radio Transmitter #710-2
Radio tagging of this female chum salmon occurred on 6 August at RM 102.9.

found 22.5 miles further upstream, a ~vement rate ~ 0.68 mph. Between
10 August and 13 August the fish entered Slough 11 at RM 135.3. On
21 August it was detected by telemetry 0.4 mile up the slough at
RM 135.7, excavating a redd. On 2 September the live fish was netted and
necropsied. It had spawned, as indicated by the 22 eggs remaining in the
coelum but the radio transmitter was not in the fish, as it was on 21 August.
The operational transmitter was located 5 meters from the redd, in the
water.
Chum Salmon, Radio Transmitter #720-1
This male chum salmon was radio tagged on 7 August at RM 120.7 (Figure EK-9).
After release this fish proceeded upstream to RM 131.4, where it was
found 32.3 hours later, a upstream movement rate > 0.32 mph. Between
1727 hours on 8 August and 0812 hours on 10 August it moved .downstream
to RM 130.7, an area just below the Fourth of July Creek confluence (RM 131.0).
For the remainder of the season the fish stayed within 0.2 mile of RM 130.7.
Between 10 August and 21 August it occupied positions along the west side of
the mainstem Susitna River from RM 130.6 to 130.7. On 23 August it
moved to the east side of the river near the confluence with Sherman
Creek (RM 130.8). On 24 August it was observed in Sherman Creek, approximately
55 yards upstream of the confluence with the Susitna River. (RM 130.8}. Between
26 August and 30 August it returned to the west shore of the Susitna

summer. On 18 September the transmitter was recovered at RM 130.9; it
was found about 15 yards inland from the west shoreline. A few pieces
of fish carcass were scattered near the tag indicating a probable predator
kill. Spawning condition could not be determined.
Chum Salmon, Radio Transmitter #730-2
Radio tagging of this male chum salmon occurred at RM 102.9 on 6 August
(Figure EK-10.). Upon release this fish moved o. 7 miles downstream
within 10 minutes. Forty-seven and nine-tenths (47.9) hours later on
a August, ~owever, it was detected 18 miles upstream at RM 120.3, a
movement rate:: 0.38 mph. During the next 7 days it progressed 6.7
miles upstream to RM 120.7, where it last detected on 15 August. On
18 August and thereafter the signal could not be detected. Extensive
efforts during the remainder of the season to locate this fish were
unsuccessful.
Chum Salmon, Radio Transmitter #740-1
This female chum salmon was radio tagged at RM 119.5 on 11 August
(Figure EK-11). Within 1.3 hours of release this fish moved 1.4 miles
downriver. Less than a day later it had moved an additional 0.3 miles
downriver. On 13 August, however, it had begun moving upstream and was
found at RM 121.7, 2.2 miles above the release site. On 15 August it
was detected at RM 121.1 and was consistently encountered there through
the field season. However, on 29 August this fish was briefly examined
in Moose Slough at Susitna RM 123.5; the fish was without the transmitter

and identified by it's Peterson disc tag number (A-333). It had regurgitated
the radio transmitter, which was located at RM 121.1. Oft 4 September
the fish was found dead in Moose Slough. It was necropsied and determined
to be spawned-out. The transmitter continued to emit weak signals at
RM 121.1 for the remainder of the season. Numerous attempts to retrieve
the tag failed.
Complete radio-tagged chum salmon movement data are shown on Table EK-1.
Coho Salmon, Radio Transmitter #650-1
Fish 650-1 was tagged on 3 September at RM 120.7 (Figure EK-12). This
coho salmon progressively moved downriver and eventually entered the
Talkeetna River between 4 and 11 September. Six hours after being
released it was detected at RM 116.1. The following day, 4 September at
1450h, it was located at RM 107.0; about 6 hours later it was detected
downriver at RM 102.5. An overflight on 11 September detected the fish
in the Talkeetna River (RM 97.0) at RM 2.7. Subsequent overflights on
the 13 and 16 September detected the individual at RM 2.7 and 3.2,
respectively.
Sometime between 16 and 18 September this coho salmon departed the
Talkeetna River (RM 97 .0) and ·moved upstream the Susitna River. The
individual apparently remained in the Talkeetna River at or near RM 2.7
on 17 September, as it was not detected by boat while tracking round
trip along the lower 0.75 mile of the· Talkeetna River (RM 97.0} and the
Susi tna River from RM 96. 8 to 120. 8. However, the next day, 18 September,

it was monitored in the Susitna River adjacent to the mouth of Chase
Creek, (RM 106.9) and by 21 September was located in the east channel of
the Susitna River at RM 111.5, immediately downstream of Gash Creek,
(RM 111. 6) •
The fish was first detected in Gash Creek (RM 111.6) at RM 0.375 by
overflight on 23 September; later the same day, the fish was located by
telemetry, during a stream survey, in a pond immediately above a beaver
dam at RM 0. 375 with about 18 other adult coho salmon. Numerous attempts
to capture the individual with a net and assess it's spawning condition
were not successful. An overflight· on 30 September did not locate the
fish. However, later that same day the spawned out, live female was
captured in a riffle-run stream reach upriver of the pond at RM 0.375.
The transmitter was missing.
A necropsy was performed. It had spawned, as evidenced by the 18 eggs
retained in the coelum.
The kype was torn where the transmitter wire modification had been
removed by someone. The Peterson disc tag remained intact and no other
external injuries or abnormalities were noted. It is not known if
spawning took place prior to and/or after the removal of the transmitter.
Coho Salmon, Radio Transmitter #650-2
This individual was tagged at RM 102.9 on 1 September (Figure EK-13).
Ten minutes after release this fish entered (and was immediately removed
from) a fishwheel on the opposite bank.at RM 102.8; forty minutes later

it was located upstream at RM 103.5. It was detected the following day
in Oxbow II at RM 119.3; this movement is equivalent to an upstream
migration rate ~ 0.56 mph or 13.4 mi/day. It reached RM 131.0 on or
before 5 September and remained within 0.1 mile of the mouth of Fourth
of July Creek (RM 131.0) through at least 16 September.
Indirect evidence suggests this fish·moved upstream Fourth July Creek
(RM 131.0) sometime during 17 or 18 September. It was consistently
detected by boat and airplane at RM 131.0 from 5 through 16 September.
However, on 18 September it was not encountered at or downstream of
RM 131.0 or along the lower 0.5 mile of Fourth July Creek· (RM 131.0). Two
days later (20 September) it was detected by overflight at RM 1.25 Fourth
July Creek (RM 131.0). The individual probably would have been detected
on 18 September upriver of mile 0.5 of Fourth July Creek (RM 131.0) had the
ground telemetry survey extended further upstream. ~sometime between 20 and
23 September the fish departed this stream; it was last located in the
Susitna River at RM 130.2, downstream of the mouth of Fourth July Creek,
(RM 131.0), on 23 September.
Coho Salmon, Radio Transmitter #660-2
This coho salmon was radio tagged at RM 120.7 on 30 August (Figure EK-14).
Upon release the individual swam 0.1 mile upstream and remained there
for at least 45 minutes. However, the following day (36 hours later)
the fish was detected 11.0 miles downstream at RM 109.8; this movement
is equivalent to a downstream migration rate of about 0.35 mph. The
individual moved upstream to Oxbow I, RM 110.4, where it was monitored
during 1 and 2 September.

SEPTEMBER
Movement of radio taqqed coho salmon transmitter number 660~2 in the Susitna. River drainage
during August and September, 1981. Adult Anadromous Investigations, Su Hydro, 1981.
This individual began moving upstream sometime during 2 or 3 September
and was located at RM 141.1 on 8 September. This movement corresponds
to an overall upstream migration rate of 0.22 mph but the fish demonstrated
considerably faster upstream movement. For example, during 3 September
it moved upstream 2.2 miles in 2.5 hours, a rate > 0.88 mph.
Sometime between 9 and 10 September the fish began moving downriver and
entered Gash Creek, (RM 111.6), about 10 days later. On 10 September
the individual was located in Slough 6A at RM 112.5; this movement is
comparable to a downstream migration rate > 0.53. mph. The fish exited
Slough 6A, as it was detected the following day at RM 113.3, and then
progressively moved downriver and remained within 0.1 to 0.3 mile of the
mouth of Gash Creek during 17 and 18 September. It was detected at
RM 0.1 Gash Creek (RM 111.6) on 20 September.
The fish was located by telemetry on 21 September at RM 0.2 Gash Creek
(RM 111.6), netted and inspected. The transmitter was intact and the
fish had apparently spawned. The anterior one third of the coelomic
cavity appeared gravid and firm whereas the remainder of the coelom was
flacid and apparently devoid of eggs. The fish was returned to the
stream alive, immediately swam 5 meters downriver and occupied an undercut
bank.
A 23 September overflight did not encounter the individual along Gash
Creek (RM 111.6); later the same day the live fish was detected visually
within 15 meters of it's release site, netted and inspected. The fish
was without the transmitter; neither telemetry or a search 25 meters up
E K - 2 8
and downriver from the capture site detected the transmitter. It was
apparently removed from the fish sometime after 21 September.
A necropsy revealed only 25 e_ggs in the coelom. The stomach was intact
and displayed no apparent damage from the transmitter.
Coho Salmon, Radio Transmitter #680-1
Coho salmon number 680-1 was radio tagged at RM 120.7 on 31 August
(Figure EK-15). Forty five minutes after being released it had moved
upstream 0.1 mile but within 8.1 hours it was detected 13.6 miles downriver
at RM 107.2. This movement is equivalent to a downstream migration rate
~ 1.69 mph. The fish continued moving downriver to RM 101.9, where it
was moni tared on 3 September. The coho salmon was consistently encountered
in the Susitna River from RM 101.6 to 102.1 through 1045h 10 September
as determined by telemetry on 3, 4, 5, 8, 9 and 10 September.
The individual began moving upstream sometime between 1045h and 1950h on
10 September and was last detected at RM 109.7 on 11 September (1600h).
This upstream movement represents an upstream migration rate ~ 0.28 mph
or 6.7 mi/day. Extensive tracking efforts during the remainder of the
season failed to locate this fish.
Coho Salmon, Radio Transmitter #700-2
Fish 700-2 was tagged at RM 102.9 on 3 September (Figure EK~l6). This
fish moved downstream to the mouth of Whiskers Slough, (RM 101. 2),
within four hours of release, and r~ined there thru 5 September. It

Coho Salmon, Radio Transmitter #710-1
This fish was radio tagged at RM 102.9 on 4 September and remained undetected
until 8 September, when it was located in the Talkeetna River (RM 97.0) at
the mouth of Chunilna Creek, (RM 5.9) (Figure EK-17). Flights on 11 and
13 September detected the individual at RM 9.0 Chunilna Creek. It was not
located thereafter.
Coho Salmon, Radio Transmitter #710-3
This female coho salmon was radio tagged at RM 102.8 on 4 September
(Figure EK-18). Within 7.1 hours after being released this ~ish was
detected 1.7 miles downriver at RM 101.1. It was next detected 9 days
later by airplane in Fish Lake, about 4.7 miles upriver of the mouth of
Birch Creek, (RM 88.0). The individual ascended a northwest side inlet
(Cabin Creek) to Fish Lake, sometime between 13 and 16 September and remained
at or near RM 0.1 of this stream thru 19 September. A 19 September ground
telemetry survey detected the spawned-out, dead coho salmon at RM 0.1
Cabin Creek. The caudal fin of the female fish was worm. About 25 eggs
remained inside the fish. The stomach was ruptured along its entire length,
probably from the radio transmitter; no other apparent tissue or organ damage
associated with the radio transmitter was noted.

Coho Salmon, Radio Transmitter #720-2
This male coho salmon was radio tagged at RM 120.7 on 2 September '
(Figure EK-19). Within 32 hours aft~r release the fish was detected
11.6 miles downriver at RM 109.1. About two hours later the same day,
3 September, it was located 1.4 mile upriver at RM 110.5. During 4 and
5 September it was encountered at RM 111.2. However, on 8 September it
moved downstream to RM 107.7 and was observed in Chase Creek (RM 106.9)
at RM 0. 3 with two other adult coho salmon. The individual supported
itself on the substrate by it's pectoral and pelvic fins; it appeared
lethargic and did not actively swim away when touched by hand. The
swimming performance of this fish was apparently adversely influenced by
insertion of the radio transmitter.
The fish departed Chase Creek (RM 106.9) sometime before llOOh the
following day as it was located in the Susitna River at RM 109.0. It
moved upriver and by 13 September was located at RM 111.3. However, 3
days later it was detected at RM 96.8 of the Susitna River, downstream
of the Talkeetna River (RM 97.0), and was consistenly encountered there
thru 7 October. Attempts to retrieve the carcass were unsuccessful.
Coho Salmon, Radio Transmitter #720-3
Coho salmon 720-3 was radio tagged at RM 119.5 on 4 September
(Figure EK-20). Within 21 hours after release this individual migrated
8.6 miles upriver, which represents an upstream migration rate 2 0.41
mph. By 8 September it was detected by airplane at RM 131.0, the upstream
migration extent of this individual. Two days later it was detected

downstream at RM 130.4; it continued moving downstream until 17 September
when it was detected at RM 117.8, near Little Portage Creek at the same
milepost.
This fish was consitent1y encountered in the mainstem Susitna River near
the mouth of Little Portage Creek at RM 117.8 from 17 Septe~~er thru
30 September. It was gillnetted on 17 September along the east bank of
the mainstem Susitna River at RM 117.9; the fish had not attained spawning
condition, as evidenced by it's silver-pink coloration and non-fluid
character of the gonads. It was detected at or within 0.2 mile of RM 117.9
on 20, 23 and 30 September.
The individual was captured alive at RM 117.8 in the outlet of Little
Portage Creek (RM 117.8) on 7 October and necropsied. The necropsy
revealed that the fish had not spawned due to the fullness of the gonads,
although the kype was eroded.
Coho Salmon, Radio Transmitter #730-3
Fish 730-3 was radio tagged at RM 102.9 on 31 August (Figure EK-21). Four
and one half hours after being released it was detected 3.0 miles upstream,
which is comparable to a 0.67 mph upstream migration rate. It was next
detected at RM 111.7 on 4 September, although 3.6 hours later it was
monitored at 2.1 miles downstream. Within 20.3 hours the fish had moved
upstream 12.2 miles; this is equivalent to an upstream migration rate of
0.601 mph. The fish apparently continued migrating upstream, as evidenced
by it being detected at RM 1.9 of Indian River (RM 138.6) on 8 September.

APPENDIX EL
CHINOOK SALMON RADIO TELEMETRY
TRACKING REPORTS
Chinook Salmon, Radio Transmitter #600-1
Chinook salmon bearing radio tag #600-1 was tagged on 24 June at RM 102.8.
This male fish immediately moved down river and remained within RM 98.0
and 99.0 of the Susitna River from 24 June through 2 July (Fi9ure EL-l).
On 5 July it was located at RM 113.0, and by 12 July it had moved downstream
and remained in the TRA for an additional five days. The upstream rate
of movement to RM 113.0 was equivalent to 0.19 miles/hour or 4.6 miles/day.
Sometime between 1645 hours (h) on 16 July and 1215 h on 17 July, the
fish began migrating upstream. On 16 July at 1645 h, it was in the
Chulitna River one mile upstream of its confluence with the Susitna
River and by 17 July at 1215 h had reached RM 104.5 of the Susitna
River. By 21 July it was detected at RM 123.6.
The overall upstream rate of movement of this fish can be expressed as
0.20 mi/hour or 4.8 mi/day. However, it did display a significantly
faster upstream movement. For example, at 1214 h on 17 July the fish
was detected at RM 104.5 and four hours and five minutes later was
encountered at RM 108.2. This translates into an upstream mi9ration
rate for this period of 0.91 mi/hour or 21.8 mi/day. A more realistic
example of movement may be from observations made on 17 and 18 July,
when the fish was encountered at RM 108.2 and 113.3, respectively. The
fish moved this 5.1 mile distance in 15.4 hours, for our upstream migration
rate of 0.33 mi/hour or 7.9 mi/day.

AUGUST
Figure EL-l. Movement of radio tagged chinook salmon transmitter number 600-1 in the Susitna River drainage
during June, July and August, 1981, Adult Anadromous Investigations, Su Hydro Studies, 1981.
From 21 July through 5 August the fish remained in the Susitna River in
the immediate vicinity of the mouth of a small stream (Fourth of July
Creek) located at RM 123.7. It is presumed that this fish spawned in
the Susitna River.
On 6 August it had drifted downstream and was encountered at RM 104.5,
where it remained through 8 August before descending further downstream.
On 9 and 10 August the fish was detected at RM 94.6 and 86.0, respectively.
Chinook Salmon, Radio Transmitter #600-2
Fish bearing radio tag #600-2 was tagged at RM 120.7 on 26 June. It
then moved upstream and remained in a pool located at RM 123.5 from 27
June to l July (Figure EL-2). During the following seven days this fish
swam upstream and by 8 July was located at RM 2.0 of Portage Creek
(RM 148.9). Overall this represents an upstream migration rate of about
4.2 miles/day.
This fish entered Portage Creek between observations on 7 and 8 July.
During its first nine days of residency in Portage Creek (8-16 July) it
was consistently encountered downstream of RM 2.75. However, on 18 July
(0820 h) it was detected at RM 8.70, which represents an upstream migration
rate of 0.15 mi/hour or 3.7 mi/day. Attempts to determine the reproductive
status of this fish during 26 and 27 July were unsuccessful. The radio
transmitter remained functional through August.

Chinook Salmon, Radio Transmitter #600-3
Chinook salmon bearing radio tag #600~3 was tagged at RM 120.7 on 8 July
(Figure EL-3). Eight days (175 hours) later it was detected at the
mouth of the Indian River (RM 138.6). This fish~ therefore had an
overall upstream migration rate of about 0.10 mi/hour or 2.4 mi/day.
The fish did display faster upstream movement, however. Between 1200 h
on 15 July and 1730 h on 16 July the fish migrated upstream 8.6 miles, a
rate of 0.29 mi/hour or 7.0 mi/day.
From 18 July through August the fish was detected within the Indian
River from about mile 4.7 to 6.1. This fish is assumed to have spawned
within this area.
Chinook Salmon, Radio Transmitter #610-1
Chinook salmon bearing radio tag #610-1 was tagged on 2 July at RM 119.2
(Figure EL-4). On 3 July at 1330 h, about 22 hours following transmitter
implantation the fish was about 0.6 miles downstream from the tagging
site. On 5 July, 43.5 hours later at 0900 h, it was located at RM 145.3,
therefore displaying an upstream migration rate of 0.60 mi/hour or 14.4
mi/day. It was monitored the next day within lower Devil Canyon, at
·about RM 151.0. From 7 July to 12 July, the fish occupied several sites
in the Susitna River upstream of Portage Creek (RM 149.3., 150.0 and
150.2), respectively, during this period.

The fish entered Portage Creek (RM 148.9) sometime between 12 and 16 July
through 30 July to 2 August. During this time the.fish was detected
between mile 2.7 and 6.3. The fish presumably spawned in Portage Creek.
Between 30 July and 2 August, the fish moved downstream out of Portage
Creek and was detected at RM 123.5 on 2 August. The following day it
was located at RM 107.1, and remained near or within Chase Creek (RM 105.3),
where it was found and necropsied on 3 August. The caudal and pelvic
fins of this specimen were severely eroded and no organs, including
gonads, remained due to the advanced state of decomposition.
Chinook Salmon, Radio Transmitter #610-2
Fish bearing radio tag #610-2 was tagged at RM 102.8 on 1 July, and
displayed a variety of movements (Figure EL-5). It dropped downstream
and remained in the TRA for about five days after being tagged. By
8 July it had moved upstream to RM 123.4, where it remained thru 18 July.
This individual departed its holding area at RM 123.5 on 18 or 19 July
and was detected at mile 2.0 of the Indian River on 21 July. During
this time the_ fish displayed some significant upstream movements. For
example, on 19 July the fish moved 1.15 miles in 55 minutes, which is a
rate of movement of 1.26 mi/hour.

It departed and re-entered the Indian River (RM 138.6) between 22 July
and 2 August. It was found in the Indian River during 21 and 22 July
and apparently departed this stream shortly thereafter, as evidenced by
its detection at RM 138.4 of the Susitna River on 24 July. Six days
later, on 30 July, it was found in the Indian River as mile 0.5.
Between 2020 h on 30 July and 1920 h on 2 August, the fish dropped out
of Indian River and moved upriver and then into Portage Creek (RM 148.9).
It remained in Portage Creek at or near mile 2.7 thru 5 August. Two
days later it was detected at RM 101.0 of the Susitna River. This
represents a downstream movement of 49.8 miles in about 43 hours.
On 10 August the fish was a RM 119.8 at 0806 h; later the same day at
2030 hit was found further downstream at RM 101.0.
Attempts to capture this fish and assess its reproductive status were
not successful.
Chinook Salmon, Radio Transmitter #610-3
fish bearing radio tag #61.0-3 was tagged on 24 June at RM 120.8. It
then moved downstream and remained in the TRA for about two weeks (Figure EL-
6}. Sometime between 12 and 16 July the fish moved upstream to the mouth
of Lane Creek (RM 113.6). It was detected by periodic overflights of
Lane Creek as far upstream as mile 1.2 from 16 to 27 July. It was
observed on 26 July at mile 1.0 but no spawning behavior was witnessed,
although turbulent water made observations difficult and could have

masked this behavior. Attempts to capture the fish by net and determine
its reproductive status were unsuccessful.
Surprisingly, on 27 July this fish was recaptured at a Curry Station
fishwheel located at RM 120.7. The fish was necropsied. The lower
caudal fin displayed wear and the posterior third of the peritonial
cavity was devoid of eggs, indicating probable spawning activity. Where
and when actual spawning took place is not known.
Chinook Salmon. Radio Transmitter #620-1
fish bearing radio tag #620-1~ a female chinook salmon, was tagged on
3 July. It then descended and remained downstream of its tagging location
at RM 119.5 (Figure EL-7). On July 7 it moved downstream to RM 106.0
and remained there through 12 July. Dur-ing the next several days it was
detected in Chase Creek (RM 105.3), 0.2 miles upstream of its mouth
located at RM 106.9. It was observed within Chase Creek about 0.05
miles upstream of its mouth on 17 and 18 July. On 19 July it dropped
out of this stream and held in the Susitna River within 0.2 miles of the
mouth of Chase Creek. Repeated attempts in July and August to recover
the fish (_carcass) and/or transmitter were unsuccessful.
The implantation of a 11 large 11 radio transmitter in this fish undoubtedly
influenced it•s behavior. No other fish radio tagged at Curry Station

displayed long-term downstream movement, with the exception of fish
bearing radio tag #670-3, which was probably adversely influenced by
handling and tagging.
Chinook Salmon, Radio Transmitter #620-2
Chinook salmon bearing radio tag #620-2 was tagged on 19 July at RM 120.7.
It then moved about 1.2 miles downstream of its tagging location and
held for about two days (Figure EL-8). Within about four days (86
hours) it migrated upstream to RM 130.8, near the mouth of Sherman
Creek. This upstream movement represented a migration rate of about
0.13 mi/hour or 3.2 mi/day. This individual remained near the mouth of
Sherman Creek about three days (25 to 27 July). Three days later on
30 July, it was detected at mile 2.9 of the Indian River (RM 138.9) and
remained there through 10 August when last contact was made,
Chinook Salmon, Radio Transmitter #620-3
Chinook salmon bearing radio tag #620-3 was tagged at RM 119.5 and
dropped about four miles downstream on the same day of tagging (Figure
EL-9). The next day (27 June) it was noted at RM 123.5. Seven days
later (5 July) it was located at RM 150.7 in lower Devil Canyon. The
overall upstream migration rate of this fish was 0.18 mi/hour or 4.3
mi/day. The migration rate was faster at times, as evidenced by its
movement 8.0 miles upstream in approximately 30 hours between 27 and 28
June, a migration rate of 0.27 mi/hour and 6.4 mi/day.

The extent of upstream migration of this individual was apparently to RM
150.7, where it was located on 5 July. However, the fish may have passed
this location sometime during 3 or 4 July. It was located at RM 149.5
and 148.9 on 6 and 7 July, respectively.
Sometime between 7 and 8 July, the fish entered Portage Creek (RM 148.7).
By 12 July it had moved out of this drainage and was at RM 144.7.
Upstream migration extent of this fish within Portage Creek was about to
mile 2.5
The fish then entered Jack Long Creek (RM 141.9) between 12 and 16 July
and remained there through 23 or 24 July. The extent of upstream migration
within this stream was about 1.25 mi.
It departed Jack Long Creek on 23 or 24 July and was. detected from 24
July through 18 August at RM 111.0. Attempts to retrieve the fish/carcass
and transmitter were unsuccessful, and the reproductive status of this
fish was not determined.
Chinook Salmon, Radio Transmitter #630-1
Fish bearing radio tag #630-1 was a female chinook salmon which was
tagged at RM 120.7 on 28 June (Figure EL-10). Following transmitter
implantation, it remained at or slightly downstream of its tagging site

for approximately 24 hours. Thereafter, it migrated upstream to the
mouth of Portage Creek (RM 148. 9), representing an approximate overall
upstream migration rate of about 4.0 mi/day. However, this individual
displayed considerably faster upstream movement on one occasion. For
example, between 5 and 6 July it·migrated upstream 6.5 miles in about 24
hours.
Sometime between 1430 h on 7 July and 0800 h of 8 July the fish began
moving downstream, wher~ it was located at mile 4.0 of the Indian River
(RM 138.9) on the latter date ~nd time. The fish held position near
mile 4.0 of this stream through 12 July, then migrated upstream and
remained within mile 10.5 to 13.0 from 16 July to .2 August. It was
consistently detected downstream at mile 7.0 to 7.2 thereafter. The
fish presumedly spawned in the Indian River.
Chinook Salmon, Radio Transmitter #630-3
Chinook salmon bearing radio tag .#630-3 was tagged on 2 July at RM 120.7
(figure EL-11). Five days (121.7 hours) later the fish was found at the
mouth of Portage Creek (RM 148.9); where it moved to at a rate of
about an 0.23 mi/hour or 5.6 mi/day.
This fish alternately entered, exited and re-entered Portage Creek
during the first half of July. It was detected at or downstream of mile
2.0 of Portage Creek by overflights on 8 and 12 July, and about 100

15 July. By 16 July it was detected at mile 2.75 of Portage Creek and
by 21 July, was encountered at mile 11.6. Thereafter, it was located at
or upstream of mile 10.8
Chinook Salmon, Radio Transmitter #640-3
Fish bearing radio tag #640-3, a female chinook salmon, rapidly migrated
upstream to the mouth of the Indian River (RM 138.6) after tagging. It
entered Indian River about 12 days later and was last detected at mile
7.0 (Figure EL-12).
Two days (41 hours) after being tagged at RM 119.5 on 3 July, this fish
was positioned at the mouth of the Indian River at RM 138.6. ·This
represents an upstream migration rate of about 0.51 mi/hour or 12 mi/day.
This individual was consistently detected at or within 0.2 mi of the
mouth of the Indian River from 5 July to 15 July and was located on 16
July at mile 0.5
Movement of this fish within the Indian River is poorly understood. It
was detected at mile 4.4 on 18 July, could not be located during overflights
on 21 and 22 July and was encountered at mile 7.0, in the mouth of a
small, incised stream on 24 July. The transmitter signal was extremely
weak that day, and the fish was not located thereafter. Whether or not
the fish spawned is unknown.

Chinook S1;1lmon, Radio Transmitter }1660-3
Chinook salmon 1660-3 was tagged on 1 July at· RM 102.8. This male
chinook salmon moved downstream into the TRA for at least two and possibly
four days after being tagged (figure EL~l3}. On 5 July it was encountered
at river mile 3.0 of the Talkeetna River. Periodic aerial monitoring
during July indicated the fish moved pro9ressively upstream within the
same drainage. It was noted at river mile 35.6 on 22 July and 4.0 miles
upstream Prairie Creek (RM 50.1} on 30 July. The overall upstream
migration rate within the Talkeetna River from 5 to 22 July was 0.08
mi/hour or 1.8 mi/day. This individual presumedly spawned in Prairie
Creek.
ChinookSalmon, Radio Transmitter #670-3
The behavior of the female chinook salmon (tag .#670-3). tagged on 26 June
at RM 120.7 was undoubtedly affected by handling due to equipment
malfunctions that occurred during transmitter implantation {Figure EL-
14). First, a 11 large 11 chinook salmon transmitter was found to be too
large to fit within the stomach of the fish. The smaller transmitter
was inserted easily. Five days after tagging this individual was detected
downstream at RM 99.6 and the fish/carcass and/or transmitter remained
there through August. It is believed the fish died from the trauma of
transmitter implantation and numerous attempts to retrieve the fish/carcass
were unsuccessful.

Chinook S~lruon, Ri:idio Transmitter #730-1
Fish bearing radio tag _#730"-1 was tagged on 22 June at RM 120.7. Approximately
five days (J05.75 hours) after being tagged, this individual moved 28.2
mi 1 es to the mouth of Portage Creek (Rl-1 148. 9), Cfi gure EL-15 L This is
an overall upstream migration rate of 0.25 mi/hour and 5.4 mi/day. A
maximum upstream migration rate of 0. 39 mi/hour or 9. 4 mi /day occurred
when the fish swam 5.2 miles in slightly less than 15 hours between 25
and 27 June.
The fish reached the mouth of Portage Creek sometime during 25 or 27
June, and remained there for two to three additional days before migrating
up that drainage. From about 29 June through 2 July, it apparently.held
in the lower 2.0 miles of Portage Creek. However, on 5 July it was
detected at mile 9.0. It remained in that general area through about 12
July, then moved downstream and held near mile 3.0 thereafter. The
transmitter ceased functioning on or shortly before 5 August. The fish
presumedly spawned while in Portage Creek.
