SUI·mARY
The Seattle and Alaska Districts of the U.S. Ar~y Corps of Engineers (CE) are
presently studying the feasibility of hydroelectric development for the
vi1lage of Perryville, Alaska. In conjunction with the Corps study, the U.S.
Fish and Wildlife Service (FHS) is environillentally assessing the project
alternatives. Thus far, field investigations have sho\/n that the fish and
wildlife resources surrounding the project tributary and the proposed
transmission power line corridors are substantial. Pink salmon were found
spawning in the project tributary. Chum and silver salmon are also speculated
to use the tributary for spawning, staging and/or rearing. Bear sign was
overwhelm";ngly abundant. Fish carcasses were found along the banks of the
tributary \'Ihere bear had been feeding. I~ature and immature bald eagles Here
observed in the immediate area proposed for the beach corridor transmission
line. Sandhill cranes and several species of vlaterfm/l were found to inhabit
wetland and open water areas in the project vicinity.
t,1easures must be developed by the CE to reduce w"ildl ife impacts associated
with the transmission line corridor. The FWS recommends that the CE not
pursue an above ground transmission line. An aerial power line could
adversely impact local eagle, waterfowl, and sandhill crane populations.
Construct ion act iv it ies assoc iated with the po\verhouse, divers ion structure
and penstock wi 11 have mi nor, short ten;] impacts on the fi sh and \/1 1 d 1 ife
resources in the ir.unediate vicinity.
The HIS recommends that access roads not be built from town to the diversion
structure or powerhouse because of the potential primary and secondary impacts
on wildlife resources located in the project area.
Finally, the FWS suggests that a FWS/CE coordination meeting be held to
discuss this project's environmental impacts prior to the project proceeding
into Phase II Feasibility.

I NTRODUCTI ON
The Alaska District of the Corps of Engineers (CE) has concluded their
reconnaissance level study which identified hydroelectric power sources at
various sites on the Alaska Peninsula. This report will provide the CE
environmental information to assist in alternative site selection and impact
analysis for small scale hydroelectric development at Perryville, Alaska.
The Fish and Wildlife Service (FWS) became involved in the Alaska Peninsula
hydro projects in 1981 \Vhen the CE sol icited our comments and suggestions
regarding environmental concerns raised by the projects (February 6, 1981).
In June 1981, a joint field trip between the CE and FWS, was conducted. The
Fish and Wildlife Service submitted their trip findings in a Planning Aid
Letter dated October 6, 1981. Fiscal year 1982 1 s effort centered on refining
the environmental informat ion base 1 ine to further assess the projects
impacts. In July 1982, the FHS submitted to the CE a field investigation
report which summarized field \~ork performed in tlay 1982.
FlJS OBJECTIVES AND l1ETHODOLOGY
Field reconnaissance trips were conducted at the proposed hydroelectric site
from r~ay 10 to 18 and July 27 to August 7, 1982. Our field investigation
objectives were as follows:
1. Identification of species composition and distribution of resident
and anadromous fish within the project areas.
2. Depth, velocity, and substrate measurements at representative reaches.
3. Site-specific wildl ife observations including wildl ife sign, denning
sites, feeding sites, migration routes, winter use areas, and calving
areas.
4. Conduct rapt or nesting surveys within the project area.
5. Vegetative description and cover typing.
6. Preliminarily assess the project impacts in regards to the level of
engineering detail.
Fishery sampling methods included the use of a 1/4" seine, minnow traps, 1/8"
fyke nets, drift gill net with variable mesh and a Coffelt BP-3 backpack
electroshocker. Minnow buckets were baited with salmon eggs and strategically
placed in the creek. Criteria used to determine sampling sites included
current velocity, depth, substrate composition and cover. Fish habitat
conducive to spawning, rearing and/or overwintering was identified.
Physical stream parameters (depth, velocity, substrate composition, stream
morphology) were quantified at several stream reaches. Hydraulic controls
were also defined. Velocity distribution and discharge measurements were made
using a Marsh-McBirney direct readout flow meter. Field data collection
procedures for potential use vlith the Physical Habitat Simulation System of
the lnstream Flow Group were followed during the course of our investigation.
Wildlife habitat and its relative use were defined with the use of helicopter
aerial surveys and extensive ground truthing field surveillances. Hr. Glenn
Elison -Refuge 11anager of the Alaska Peninsula National Wildlife Refuge, at
King Salmon, Alaska, assisted in the terrestrial description of the project
area.
DESCRIPTION OF PROJECT ALTERNATIVES
The Corps of Engineers Seattle District has developed and will evaluate a set
of conceptual project plans for Perryville (CE, 1982).
The eE's preferred site is on a small unnamed tributary of the Kametolook
River, approximately five miles north-northeast of Perryville, Sections 1 and
12, T. 49S, R64W, (Figure 1). The project is being designed to provide power
only for the village of Perryville. Preliminary plans call for a 40 foot
wide, 10 foot high diversion structure to be built at 700 foot-mean sea level
(t'lSL). The structure would be constructed of timber and have a 30 0 plank
facing. Approximately, a one-acre reservoir Vlould be created as a result of
constructing the structure.
A three thousand foot penstock, constructed of lowhead pipe, would connect the
diversion structure to the powerhouse. The CE's preferred powerhouse location
would be built at the 200-250 foot elevation-MSL. A raised platform would be
constructed to hold the powerhouse. Two sizes of powerhouse are being
evaluated, (1) 200 kW unit utilizing 5.6 cfs and 12 inch pipe and, (2) 400kW
unit utilizing 10.7 cfs and 16 inch pipe (Sweger, 1982). At this time, the
powerhouse tailrace is presumed to enter the parent stream at or above
elevation 200 feet-MSL.
The Seattle Corps District proposed two power line route alternatives for the
Perryvi lle hydropower study: (1) an inland route and, (2) a beach route
(Figure n. Each one will be undergo feasibility evaluation as an above
ground and buried transmission line. The inland route begins in the project
canyon and travels 13,000 to 16,000 feet in a southwesterly direction towards
the town of Perryville. The last 4,900 feet of the corridor deviates from a
southwesterly direction and travels southeast in order to traverse a saddle in
the cliffs which surround the town. Width dimensions for the corridor have
not as yet been delineated by the CEo
The beach route aHcrnntive originates in the project canyon dr,d Lravels
12,000 to 14,000 feet in a southeasterly direction. This portion of the
transmission line lies between the base of the foothills and the Kametolook
River. Approximately 5,000 feet from the mouth of the Kametolook River, the
transmission line crosses the channel and travels south\vest, paralleling the
shoreline. The total length of this route is approximately 28,000 feet. As
was the case for the inland route, no width dimensions for the corridor have
been developed at this time.
Access roads are not proposed to be built by the CE in conjunctions with this
project.

FISH AND WILDLIFE RESOURCES HITHOUT-THE-PROJECT
The village of Perryville is located on the south shore of the Alaska
Peninsula just south of Chignik and west of Coat Cape in the Stepovak Bay
area. The climate of the area is generally considered a moderate, polar
maritime climate, characterized by high \~inds, mild temperatures, protracted
cloud cover and frequent precipitation. During 11inter, precipitation often
falls as rain on the south side of the Peninsula near sea level.
Precipitation averages 160 inches in the vicinity of Chignik on the Pacific
coast, which is just north of Perryville. Growth of vegetation usually does
not occur until late tolay or early June. The first freezing weather, on the
Pacific side of the Peninsula, generally does not occur until October or
November.
SURVEY OF PROJECT TRIBUTARY MORPHOLOGY
The mechanics of flow in the project tributary is a cornplex subject that
requires special attention. The creek is a dynamic system which contains a
variety of fish and riparian habitat. t-lajor factors that contribute to the
creeks dynamic nature are: (1) the continual evolution of channel patterns,
(2) channel geometry, (3) bars and (4) forms of bed roughness vlith changing
water and sediment discharge. The project tributary exemplifies three types
of channel patterns: (1) straight (upper, upper reach) (2) braided (upper,
lower reach) and (3) meandering (lower, upper and lower, lower reaches)
(Figures 2 and 3).
Above the diversion site (705 feet-11SL) (Figure 2, Site 1), the stream
meanders back and forth between steep sloped hills until at even higher
elevations it gradually branches out to the uppermost areas of its watershed.
The flow is swift and steady. Discharge measurements taken at the diversion
site on July 30, 1982 were 24.7 cfs. Channel width varied between 10 to 15
feet. Large grave 1 and course sand composed the major ity of the stream beds
substrate.
The channel morphology rernains as previously described for 50 yards downstream
of the diversion site. At that point, the creek drops sharply over six falls
onto the canyon valley floor, which begins at the 200-300 foot elevation.
Large boulders and cobble constitute the major portion of the creek's
substrate through the 400-500 foot drop.
Between the 200-300 and 50 foot e 1 evat ion-t1SL, the channel meanders between
the canyon walls (Figure 2, Site 1). Alternate cobble/gravel bars line the
banks. Flow is swift and uniform. Hydraul ic chutes and snags occassionly
occur and force the creeks discharge to overflmv its bank and erode a new
channel. Shallow pools were not numerous, but undercut banks were found to be
numerous in this particular reach. Three sl~lall creeks entered the tributary
between the 100 and 500 foot elevation contours. Flows appeared substantial
because of heavy rains prior to our field visit. Suballuvial flow was
strongly evident. Discharge i,leasurernents taken in the project creek at the 50

As the creek channe 1 approaches the base of the northeast canyon wa 11, it
makes a turn into the Kametolook floodplain and follows the 50 foot contour
(Figure 2, Site 3). The tributary branches into tvlO channels when it flows
into a large snag of boulders and dead alder/willow. During our Hay trip,
about half of the creek's flow diverted into each channel but during August,
all the flow was diverted into the newly formed main channel which flowed away
from the base of the foothills towards the lower floodplain.
The main channel flows out into a flat, approximately ten acre area dominated
by wetland vegetation (Figure 3, Site 4). The channels flow is further
distributed through the wetland by distributaries which gradually interconnect
to reform a single distinct channel (Figure 3, Site 5). From this point
downstream the channel meanders back towards the foothills (Figure 3, Site
6). One small creek enters the main branch of tile project tributary near
Figure 3, Site 5 (discharge 2.3 cfs, August 1982), its origin of which is
unknown.
The meandering channel consists of alternating bends, giving an S-shape
appearance to the plan view of the project tributary. Discharge measurements
indicated flows between 7 and 11 cfs. Deep pools are found in the bends and
shallow crossings exist on the short straight reaches connecting the bends.
The lower reaches of the tributary exemplify a pool, riffle, run morphology.
The thalweg flo\",s from a pool though a crossing to the next pool forming the
typical S-curve of a single meander loop. The pools tend to be somewhat
triangular in section with point bars located on the inside of the bend. In
the crossings, the channel tends to be more rectangular, widths are greater
and depths are relatively shallow. At low flows the local slope is steeper
and velocities are larger in the crossing than in the pool. Alluvial islands
and mid-channel gravel bars are periodically found in the channel. A single,
long chute (side channel which carries appreciable flows at least during high
stages) exists between Site 5 and Site 7 (Figure 3).
The main channels substrate between Site 5 and Site 6 is composed of small
gravel with silt/sand dispersed throughout. The channels width varies greatly
between 3 to 30 feet. Portions of the streams bank is in a state of
degradation. Severe bank undercutting causes alder/willow snags to occur.
As stated previously, the project tributary splits near Site 3 (Figure 2).
The channe 1 that para 11 e 1 s the base of the footh ills appeared to be at one
time the main channel, but has since cvolvc<Jinto a side channel.
During our trip in May, the side channel had SUbstantial flows (Figure 3, Site
4a). Deep pools existed in the bends and point bars developed accordingly.
Between Sites 4a and Sa, smaller side channels diverged off and flowed into
the wetland area (Figure 3, Site 4). The mechanics for this occurrence are
not fully understood at this tir71e. Distributaries and interdistributaries
collected the water from the wetland and formed distinct channels, which in
turn flowed into the previously discussed main channel.
Below Site Sa, the secondary channel (its flow visibly reduced) continued to
flow at the base of the foothills, until it discharged its flow into another
wetland pocket (Figure 3). Gradually, inter'tributaries collected the water
from the wetland and formed a distinct channel in the area of Site 6a. This
channel flowed at the base of the foothills and in turn flO\ved into the IIlain
channel near Site G (Figure 3).
7
Circumstances in August were quite different than those in t1ay. The
previously flowing side channel had no flow in August. All the project
tributaries surface flow was diverted into the main channel, which flowed out
into the Kametolook floodplain. Suballuvial flow in the secondary channel did
form shallow pools in the creek's bends. Suballuvial flow did surface between
Site 5a and 6 because surface flow was visible (Figure 3).
The vicinity of Site 6 has a wide variety of limnological/hydrological
features (Figure 3). Two open water areas lie at the base of the foothills;
one is approximately two acres and the other, one acre. Haterfalls and seeps
flow from the side of the cliffs and discharge into the project tributary.
Proceeding downstream beloH Site 6, the tributary (having now re-collected
discharge from its distributaries and side channels) meanders back towards the
Kametolook River. Discharge measurements taken just upstream from the mouth
indicated a flow of 16 cfs (August 1982). Substrate composition remains as
gravel and coarse sand. Deep pools and undercut banks are abundant. The
mouth region has a large gravel bar on the left bank and a deep pool on the
right bank (looking upstream). Vegetation canopy cover along the banks was
more abundant in the mouth vicinity than in those reaches between 200-600
yards upstream.
POWER GENERATING FACILITIES VICINITY
The project area described as the II power generating facilities vicinity"
includes the terrestrial and aquatic habitat between the diversion structure
(including the inundation area) and the pO\verhouse (including its tailrace).
t·10re specifically, the area bet\Veen the 50 to 705 foot elevation contours
within the project canyon (Figure 2).
Terrestrial Resources
The tributary valley floor slopes gently until it reaches approximately the
200 to 250 foot-MSL at which point it begins to rise rapidly to about the 700
foot contour. Above the 700 foot contour, the va 11 ey is narrow with steep,
grassy meadows. The valley floor is dom-inated by alder (Alnus crispa). The
slopes surrounding the valley floor are approxi~ately 50% a1der and 50%
herbaceous meador/so The grass association gives I'/oy to heath as elevation
illcreJses. The llreJS surroullLlin~ the poLellLilll pOI'lerhouse sites Jre
relatively flat. I'loss-lichen mats are scattered throughout the alternative
sites. The predominate vegetation cover at all the sites is a alderhvillow
mix. The substrate beneath the tall shrubs is composed of cobble and gravel.
It was noted that dur-ing high flows, the creek v/Ould flood the valley floor
and erode away the topsoil, exposing the unstable cobble and gravel
substrate. As a result of this flooding, alder and willO\v are sv/ept into the
creek and form snags. Appendix A graphically delineates the vegetation types
found in the power generating facilities vicinity. Table 1 lists those plants
species found at the diversion and powerhouse sites and along the penstock
route.
Wildlife use of the valley appears to be low. A lightly used game trail,
probably bear, was evident on the south side of the tributary valley floor.
One set of moose tracks \vas found on the slope above the proposed dam site.

On the surrounding hillsides one set of old bear tracks was evident as \'Iere
scattered diggings which may have been attributable to brown bear.
Surrounding slopes appear suitable for bear denning though no dens were
evident. Cricetidal burrows, runways and feces were abundant throughout the
marshland and upland areas. One willow ptarmigan was seen near the Perryville
diversion site in May. Willow buds were heavily being fed upon by ptarmigan.
Their droppings were abundant near alder and willow thickets above 600
feet-l~SL. Perryville residents report ptarmigan by the "hundreds" in the
mountains surrounding town. One shrike vias observed near 400 feet-t·1SL near
the hydropower site. Near the mouth of the canyon, one immature bald eagle
was seen flying overhead. Magpies ravens, chickadees, and dippers were found
throughout the project canyon.
Aquatic Resources
Because of adverse hydraulic conditions in the upper reaches of the project
tributary, fish use is severely limited. Some areas do exist in the upper
reaches which are conducive to fish spawning and/or rearing; however, fish
blocks prevent access to these areas. The streams upper most reaches have a
substrate that consists of large cobble and boulders. Hydraul ic chutes are
abundantly scattered throughout the upper most reaches. Dolly Varden
(Salvelinus malma) were found to inhabit the stream segments on the canyon
floor. Waterfalls above the 300 foot-tlSL contour, physically impair upstream
fish movement. Stream segments sampled above the diversion site were void of
any fish species.
Aquatic macro invertebrates were found to inhabit the entire upper reach of the
project tributary. Some of the more abundant species were represented by the
genera Ephemerella, Ironodes and Limnephilius. High numbers of Coleoptera and
Turbellaria were also collected. All the aforementioned invertebrates are a
common source for fish food.
Periphytic algal mats were not observed to occur; however, diatomaceous films
covered most of the silt and rocky substrate throughout the creek course.
Phytoplankton nor zooplankton were sampled for during, any of our field
invest igat ions. Because of the 1 irnited age of the creeks water, low water
temperatures, and its severe turbulence, we do not believe the plankton
community to be extensive or well established.
Favorable anadromous fishery habitat exists throughout the lower reaches of
the tributary (Figure 3). During our May investigations, juvenile Dolly
Varden (Salvelinus malma), chum salmon (Oncorhynchus keta) and pink salmon
(Oncorhynchus gorbuschaJ vlere collected with the use OTrilinnov/ traps and/or
fyke nets. Adult pinks and Dolly Varden were captured in the lower reaches of
the project tributary during August. Adult chum were seen on only one
occasion in the mouth of the tributary near the Kametolook River. The
Kametolook River, has documented chum, pink and coho salmon runs (ADF&G,
1978). Pinks were seen spawning throughout the entire lower reaches of the
project tributary, particularly in pool/riffle segments. He estimate that
300-500 pinks \vere using the tributary during our August trip. The uppermost
extent of pink salmon use occurred in the vicinity of Site 5 (F"igure 3).
Water temperatures at the spawning sites ranged from 10 to 11.5 0 C.
10
The majority of aduH pinks and Dolly Varden were seen using the deep pools
and vegetated undercut banks which exist throughout the lower reach. A large
number of gravel bars offer excellent spawning habitat. Gravel sizes ranged
from one to six centimeters. Discharges for the tributary ranged from 9.9 cfs
in t1ay to 15 cfs in August. Particular segments of the creek could pose to be
a fish block if flow drops a yet to be determined amount. For the
aforementioned reason, we began to collect instream flow data during our
August trips. Figures 4 and 5 graphically illustrates two representative
reaches used in our instream flow measurements. Figure 4 represents a
riffle-run segment which in turn depicts spalt/ning habitat and potential fish
blocks (related to flow). Figure 5 represents a pool-riffle segment as
related to staging and rearing habitat for adults and juveniles. Appendix B
contains the field data, discharge and cross sectional profile data for all
the August transects. Further instream flow \vork may be required should the
proposed project affect downstream releases. This topic will be discussed in
latter portions of this report.
TRANSt1I SSI ON LI NE CORRIDORS
Terrestrial Resources
Both the inland and beach corridors have diverse vegetation types which are
conducive to supporting a variety of fish and/or wildlife (Appendix A). The
main vegetation types represented include coastal alder thickets, floodplain
thickets, treeless bogs, moist and wet tundra and palustrine/lacustrine
systems. Table 2 lists the plant species occurring within the hID
transmission line corridors.
There are two d i st inct "hab itat type" segr.lents to the beach route: (1) the
foothill segment and (2) the beach segment. The foothill segment can be
defined as that area on the Kametolook River flood plain between and
foothills/cliffs to the north and the river channel to south. The beach
segment consists of a 3,000 foot wide bank of habitat that parallels the
shoreline (Appendix A).
The lower reaches of the project tributary are included in the foothill
segment of the beach route. ~1ore diverse wildlife habitat exists in this
reach than that in the upper tributary reaches (Figure 3). IJetland areas and
pockets of open v/ater at the base of the cliffs are conducive to supporting
watcrfmJl; ten pair of unidentified \;laterfOl~l I/cre seen in the aforerlentioned
area during tlay. It \;las unclear as to whether Itlaterfowl I/ere nesting or not.
A female green-winged teal and nine ducklings Ivere found using the mouth of
the project tributary. t~allards were seen flying through the area as they
headed up the Kametolook River valley.
Shore birds were observed using the 10lver reaches of the project tributary.
Sandpipers, black-bellied plover, greater yellowlegs and snipe \vere seen in
low wetland areas on either side of the river.
Magpies were common throughout the area. Nests were observed in several alder
th i ckets at e 1 evat ions of 1 ess than 200 feet-tlSL. K i ngfi shers Ivere abundant ly

Adult and immature bald eagles were seen commonly along the cliffs of the
foothills segment. Preliminary surveys indicate the presence of three adults,
two immatures (dark phase) and two to four immatures (1 i ght phase). Rock
outcroppings in the foothills provided the raptors perching sites. On several
occasions, immature bald eagles were seen perched on dead, standing alder
trees that 1 i ned the project tr i butary and Kameto look River. Nest i ng sites
were not observed during our field investigations.
Large mamma 1 use of ~he footh i 11 s segment was evident. Numerous bear tra i 1 s
were seen crisscrosslng the project tributary and also seen leading from up
the Kametolook River valley down to the mouth. The foothills also had trails
up and down its face. Fresh bear sign was abundant. Hardly a gravel bar or
stream bank was untouched by bear. Partially devoured salmon were found among
the alder thickets. Moose sign was not abundant. Isolated tracks were
occasionally found along the tributary.
Evidence of small mammal use was limited to fox and wolverine tracks.
Cricetidal burrows, runways and feces were abundant throughout the marshland
and upland areas.
The beach segment of the beach route alternative consists of a series of
low-ridged sand dunes, which have been stabilized by alder and grasses. Lakes
are commonly found in the depressions (Appendix A). An "island" of high
ground (sea level to 535 feet-MSL) is situated north of the ridges behind the
town of Perryville. Vertical, rocky cliffs up to 150 feet high face the ocean
front.
Waterfowl use of the beach segment was extensive. Red-throated loon, pintail,
red-necked grebe and ma 11 ard were seen on the long narrow 1 akes para 11 eli ng
the beach. A flock of twenty harlequins were seen in the surf near the mouth
of the Kametolook River. White-winged scoter were observed in the mouth of
the Kametolook River and severa 1 red-breasted mergansers were seen flying over
the Kametolook River. Plovers, cormorants, and tufted puffins were observed
along the surf.
Bald eagles were observed within the beach segment. TI'IO imrnatures (light
phase) were seen perched on drift \'iOod along the beach. One adult eagle was
found perched on a rocky outcrop in the cliffs overlooking the beach front and
coastal ponds.
Bear and moose sign I'lere observed. I'loose tra i 1 s I'lere found

the river.
The inland transmission route has a more uniform habitat base. Palustrine
emergents and moss-l ichen habitat types cover large areas. Sections 14 and
the northern portion of 23, T49S, T6411, consist largely of sedges, mosses and
other moist soil plants (Appendix A). In the vicinity of the project canyonts
I~outh, scrub-shrub cor~rnunities become established and alder/willOl'/ provide the
majority of canopy cover. The Kametolook Rivers floodplain is made up of
volcanic gravels that have scattered islands of alder/willow. I'losses and
16
lichens as well as annuals and perennials provide some successional
stability. The area immediately behind the town of Perryville consists
largely of open-taTl shrubs. Alder thickets are weTl established on ancient
sand dunes. Grassy meadows are scattered throughout the th i ckets and on the
slopes of the foothills and cliffs that surround the town. Small ponds exist
in the depression between the sand dune ridges.
TViO pair of green-winged teal and three pair of mal1ards and pintaiTs \~ere
seen in May at a marsh behind Perryville. Parasitic jaegers, one dark and one
light phase, were also seen in a marsh behind tovm. Three sandhill cranes
were seen flying along the Kametolook River during ~1ay and t\~O were seen in
August. Perryville residents report that a few cranes nest in the marsh
behind the vil1age. ~Jhistling swans were not observed; however, they, too,
were reported by 10ca1 residents to nest in low numbers in a marsh behind
Perryvi11e. Adult and immature bald eagles were seen commonly along the
beaches at Perryville and on the marsh behind the town.
Mamma1 use of the inland transmission 1ine corridor was much more reduced than
that of the beach route. Caribou sign was not seen at Perryvil1e; however,
residents report that scattered bands of caribou do exist in the area. Fox
sign was common and wide1y scattered; residents of the area trap fox. One
w01f track was seen on a sandbar a10ng the Kametolook River. Mink are
reported1y trapped on the marsh direct1y north of town. Perryville residents
report trapping otter in the marsh adjacent to the Kamet0100k River. One bear
trai1 was found fo110wing the 50 foot contour around the c1iffs north of town.
WITH-THE-PROJECT ENY I RON/1ENTAl ASSESSt1ENT
The environmenta1 impacts associated with hydroelectric deve10pment at
Perryville, have the potentia1 to be adverse. The instaTlation of aeria1
transmission lines represents the greatest area of concern. POvler line and
associated structures have long been recognized as a direct and often
substantial mortality source to birdlife (Olendorff, ~1iller and lehman, 1981;
Avery, 1978; Wil1ard, Harris and Jaeger, 1977). Long-term impacts associated
with aeria1 transmission 1ines involve alteration of 10ca1 bird movements and
disruption of migration routes.
Bald eagles in the project area would be threatened by an above ground
transmission line. RafJtors are electrocuted by pOller lines because of lila
seemingly unrelated yet interactive factors: (1) the distribution, size,
behavior, and other biologica1 aspects of raptors, and (2) designs of electric
industry hardware which place electrical wires close enough together that
raptors can simutaneously touch two or more of them with their wings or other
parts of the ir bod ies. Between 70 and 90 percent of all raptor morta 1 it ies
a10ng e1ectric distribution lines are eagles.
Raptors are basica11y opportunistic and thus use power lines and support
structures for perching, nesting and as hunting perches. "St"ill" hunting from
a perch is an energetical1y conservative way to find prey provided good prey
habitat is within an eag1es vie\-I frolil the perch.
17
Some power poles are preferred by the eagles because they provide considerable
elevation above the surrounding terrain, thereby providing the birds a wide
range of vision, easy takeoff, and greater attack speed when hunting. During
our field investigation, bald eagles were seen perching on the rocky outcrops
located in the cliffs paralleling the Kametolook River. One immature eagle
was also seen perching on a 10 foot high dead alder along the river.
Studies have shown that most eagle mortalities along power lines are immature
or subadult birds. This susceptibility of immature and subadults to
electrocution involves several factors, but none is more important than flying
and hunting experiences. Immature eagles are generally less adept at
maneuvering than adults.
~\inor and short term environmenta 1 impacts are expected to occur as a result
of constructing a powerhouse, penstock and diversion structure. Large mammal
use is limited to bear and/or moose trails leading through the vicinity of the
project structures to the Kametolook River floodplain. Individuals using such
trails will be displaced to different areas, and in turn, create nevi trails.
Because steep, rocky cl iffs border the penstock route, raptor use can be
speculated to occur; however, no sightings \'iere made in this area during our
trips. Hore seasonal observations are needed to conclusively state that no
eagles inhabit or nest along the proposed penstock route.
The area proposed to be inundated by the diversion structure has minor
wildlife use. The steep, herbaceous slopes bordering the impoundment site
offers little habitat for large mammal use. Even though bear feces were found
along the stream, itls more likely that bear use the stream as a traveling
corridor rather than an area used for denning and/or foraging. The
approximate one acre impoundment would temporarily displace mammals from using
the impacted area. Fish use \."as not documented in the impoundment area even
though macro-invertebrate food organisms were plentiful.
Anadromous fish have been documented as inhabiting the lower reachers of the
project tributary. Field studies have shown that the upper limits of
anadromous fish use is in the vicinity of Site 5 which is well below the
powerhouse. If a run-of-the-river alternative is chosen by the CE, lileasures
will have to be taken to insure an instream flow and stable seasonal discharge
to the lower reaches. In light of the possibility of a run-of-the-river
project, we have initiated collecting instrealll flO'd data (AlJPcndix 8).
Because of the remoteness of the project site the use of helicopters would be
anticipated. An access road from the powerhouse and diversion structure to
the village may be required. Any access road would have to cross the
Kametolook River and traverse the river valley. Construction activity and
subsequent secondary use (increased hunting accessability, wildlife harassment
as a result of increased recreational use) of the access road could alter bear
movements through the valley, the degree of which is not known at this time.
Local residents and preliminary engineering preferences suggest that a
transmission route should follow the base of the foothills on the southeast
side of the Kametolook River. Field observations have shown that the base of
the mountains offer diverse viildlife habitat, similar to an "edge effect".

FWS RECOM~ENDATIONS
Based on our current knowledge of engineering and environmental information
for the hydroelectric project at Perryville, Alaska, the FWS makes the
following recommendations:
1. ~1easures must be identified to reduce wildlife impacts associated
with the transmission line corridor.
a. Our preferred ranking of transmisson line corridor alternatives
is as follows:
1. Inland corridor; buried line
2. Beach corridor; buried line
3. Inland corridor; above ground line
4. Beach corridor; above ground line
b. If an above ground power line alternative is chosen, measures
must be taken to raptor-proof the entire line's length.
2. The powerhouse and tailrace complex should be placed in the project
canyon above the 100 foot contour.
3. I n order to protect the anadromous fi sh use of the 10lver reaches of
the project tributary, the CE must recognize that an instream flow
exercise may be necessary to deterr.line stable and seasonal releases.
4. Penstock and diversion structures should be constructed with the use
of helicopters.
5. An access road to the diversion and powerhouse site should not be
built because of its primary and secondary impacts on local wildlife
(waterfov/l, large r.lar.lrnal and bald eagle).
As advanced engineering and design data becorile available, additional studies
will be needed to quantify specific impacts, which in turn will provide
information to formulate a mitigation package. Such an effort must be
completed before Final Phase II Feasibility is determined by the CEo
The F\~S suggests that a FIJS/CE coordination r.leeting be held to discuss the
aforementioned recownendations before the project proceeds into Phase II
Feasibility.
Finally, it has come to our knowledge that the desired level of engineering
detail needed for us to initiate our draft Fish and Wildlife Coordination Act
Report (FHCAR) is not yet available. Subsequently, we ~Jill not be able to
submit our draft FWCAR by the 15 November, 1982 deadline. A new draft and
final FWCAR due-date will need to be negotiated once the necessary
environmental studies have been completed and detailed engineering plans have
been submitted to us for our review and incorporation.

Miscellaneous vegetation descriptions v/ere specifically developed for those
areas not clearly categorized into either of the above classification
systems. A textual narrative is provided below for each of the codes used on
the vegetation map.
Additional studies will help to refine and standardize future vegetation r.laps
for the Perryville area.
Riverine System
The system is bounded by the banks forming the outer limits of the depression
within \'/hich the stream occurs. Water is usually, but not always, flowing.
Upland islands or Palustine wetlands may occur in the channel, but they are
not included on the Riverine System. Elements of the Palustine Syster.J may
occur adjacent of the Riverine System, often on a floodplain. Subsurface
water controls, to a great extent, the delineation of wetlands.
RUPOSS -Riverine u errenial, 0 en scrub-shrub
The grad1ent 1S 19 an ve OC1ty 0 t1e water fast. The substrate
consists of rock, cobbles, or gravel with occassional patches of coarse
sand. The flora is characteristic of running water, and there are fevi or
no planktonic forms. There is very little floodplain development.
Alder/willow occur along the banks with a herbaceous understory. t·leadO\'is
occur on nearby slopes and among the willow/alder thickets.
RUPSS -Riverine, upper perrenial, scrub-shrub
The gradient is high and velocity of the water fast, the substrate
consists of rock, cobbles, or gravel with occasional patchs of coarse
sand. The flora is characteristic of running water, and there are fe~'i or
no planktonic forms. There is very little floodplain development.
Alder/willow dominately occur to form dense stands. Herbaceous
understories are present but herbaceous r.leadows are not.
RISS -Riverine, intermittent, scrub-shrub
In this subsystem, when the water is not flowing it may remain in isolated
pools. Suballuvial flow is present. Scrub-shrub areas are dominated by
Hoody vegetation less than 6 III (20 feet) tall. The species include true
shrubs, young trees, and trees or shrubs that are small or stunted because
of environmental conditions. Alder-willow stands dominate the stream
banks. Herbaceous understories are present.
A-2
RUB -Riverine, unconsolidated bottom
This section refers to substrate \~ith vegetative cover less than 30%.
Unconsoldidated bottoms are characterized by the lack of large stable
surfaces for plant and animal attachment. The entire length of the
Kametolook River's river bed is included in this category. Aquatic
vegetation was not found to be established in the river channel.
Palustrine System
The Palustrine System includes all nontidal wetlands dominated by trees,
shrubs, persistent emergents, emergent mosses or lichens. It also includes
the small, shallow, permanent or intermittent water bodies often called
ponds. Palustrine wetlands may be situated shoreward of lakes, river
channels, or estuaries on river floodplains, in isolated catchments, or on
slopes.
PML -Palustrine moss -lichen
This c1ass inc1udes areas where mosses or lichens cover substrates other
than rock and where emergents, shrubs, or trees make up 1 ess than 30% of
the areal cover. The only water regime is saturated.
PE -Palustrine emergent
This class is characterized by erect rooted herbaceous hydrophytes,
excluding mosses and 1 ichens. This vegetation is present for most of the
grovling season in most years. These 'detlands are usually dominated by
perennial plants and occasional patches of open, standing water.
PAB -Palustrine aquatic bed
This class includes wetlands and deep\~ater habitat dominated by plants
that grow principally on or below the surface of the water for most of the
growing season in most years.
PSS -Palustrine, scrub-shrub
The class scrub-shrub includes areas dominated by \~oody vegetation less
than 6 m (20 feet) tan. The species include true shrubs, young trees,
and trees or shrubs that are small or stunted because of wetted
environmental conditions.
Lacustrine System
This system includes wetlands and deepwater habitats with all of the following
characteristics: (1) situated in a topographic depression or a dammed river
channe 1; (2) 1 ack i ng trees, shrubs, pers i stent emergents, emergent mosses or
1 ichens with greater than 30% area 1 average; and (3) tota 1 area exceeds 20
acres. Similar wetland and deepwater habitats totaling less than 20 acres are
also included in the Lacustrine System if the 'dater depth in the deepest part
of the basin exceeds 6.6 feet at low water. Islands of Palustrine wetland may
be within the boundaries of the Lacustrine System.
LAB -Lacustrine aquatic -bed
This class includes wetlands and deep\~ater habitats dOrilinated by plants
that grow principally on or belo'd the surface of the water for most of the
growing season in most years.

KGSS -Kametolook gravel floodplain, scrub-shrub
The dynamic nature o:r-the Karneto look R ivers course a lters the vegetat ion
zones within its floodplain. This class refers to those areas previously
unindated by the Kametolook River and are now successionally
revegetating. Fireweed, short alder and willow dominate. Patches of moss
and lichen cover the volanic gravel and sand.
ErUB -Estuarine, intertidal unconsolidated bottom
This class consists of tidal habitats and adjacent tidal wetlands that are
usually semi-enclosed by land but have open, partly obstructed, or
sporadic access to the open ocean, and in which ocean water is at least
occasionally diluted by freshwater runoff from land. The bed of this
estuarine system is composed of volanic sands. Marine algae species
dOI;linate the intertidal area. Beach-rye grass vegetates the banks
surrounding the areas.
