KNIK ARM CROSSING
RECONNAISSANCE OF FRESHWATER HABITATS
POTENTIALLY AFFECTED BY THE NORTH APPROACH
CORRIDORS OF THE KNIK ARM CROSSING PROJECT
A.INTRODUCTION
This study was initiated as part of a baseline data collection program
relating to environmental analysis of the proposed Knik Arm Crossing Project.
North approach highway corridors,connecting the crossing itsel f with the
Parks Highway,would traverse substantial areas of relatively undisturbed
terrain including crossing of numerous streams.The biological and physical
characteristics of most of these streams were not well known,especially in
the v icinity of proposed north approach highway crossings.Therefore,a
study program was initiated to fill specific information gaps relative to
freshwater habitats.
The p'rogram was designed to address the following questions or needs:
1.Determination of whether a stream is a fish stream relative to per-
mitting and mitigation requirements
2.Assessment of mitigation needs and opportunitie~for these fish streams
o Overall assessment of fish value to provide information needed
to make major decisions on crossing mode;e.g.bridge vs.culvert
o Identification of species composition and dominant fish values
so that "design"fish species and life stages can be selected
as a ba~is for design of highway drainage st~uctures;e.g.determ-
ination of acceptable culvert velocities
o Assessment of optional road alignments within limits of the corri-
dors to avoid sensitive habitats and minimize construction impacts
o Identification of sensitive time periods
I-I
3.Assessment of aquatic habitat values at a level of detail sufficient for
impact analysis as required by the EIS process
o Assessment of values in the vicinity of the road crossing site
to allow assessment of direct impacts from road construction
and operation
o Assessment of values within the stream system as a whole to allow
assessment of indirect impacts (e.g.from downstream siltation)and
secondary impacts (e.g.from human exploitation).Stream-wide
field data were only collected for those streams where the existing
information base was too small to allow a reasonable impact
assessment
During initial analysis of potential north approach corridors,several
logical alternatives were identified.Because of seasonal constraints on
biological field work,it was necessary to conduct the study prior to the
formal decision regarding which corridors would be considered in the EIS.
For purposes of this study,therefore,the·two most ·likely alternatives
(Houston and Wasilla corridors)were sel ected fo r further ev al uat ion.
Whjle the study was in progress a modification of the Wasilla corridor,the
Big Lake corridor,was also selected for evaluation.Representative align-
ments within the corridors were drawn by project engineers and used as the
basis for stream investigations (Figure 1 and Plate 1).
B.GENERAL METHODOLOGY
Because the data requirements and physical characteristics varied great!y
among the study streams,methods used on the streams also varied.Specific
methodology will be described in the discussions for each stream in
subsequent sections of this report.This section discusses onl ygeneral
methodology.

Pre-Field Assessment of Data Needs
Prior to initiation of field investigations,an inventory was made of the
information already available for each of the streams to be crossed by
the proposed al ternative roadways as determined from map interpretation.
Interviews were conducted with Alaska Department of Fish &Game (ADF&G)field
personnel to gain additional knowledge for the subject streams.ADF&G files
and reports were examined as applicable.Field data collection needs for
each stream were determined on the basis of the information available and the
needs of the Knik Arm Crossing Project.
Overall Approach
A two-man biological team surveyed the alternative north approach routes
travelling via helicopter with supplemental visits to some streams via ground
transportation.Investigative methodology and sequence to be applied at each
stream crossing was appro~imately as follows:
1.A stream reach about 0.5 mile (0.8 km)wide centered on the proposed
roadway was reconnoitered from the air.Physiographic features 0 f the
stream were noted and aerial photographs taken.The 0.5 mile zone was
assumed to incl ude the area where the actual crossing would ultimatel y
occur as well as a substantial distance on either side.
2.Using a combination of aerial and ground travel,a selected area
within the 0.5 mile zone was sampled for fish.Sample sites included a
range of typical habitat types.Fish were sampled using a variety of
methods including backpack electroshocker,"beach seine,minnow traps,
visual observation,and angling •.The primary emphasis was to obtain
qualitative samples of fish distribution.However,standard methods
were employed for some sampling techniques so that samples within and
among streams could be quantitatively compared on the basis of catch per
unit effort.
Most fish captured were measured and then releasee!.A few fish were
retained for confirmation 0 f species identi fication.

If initial observations and sampling indicated that fish use was
improbable,then the investigation was aborted or abbreviated.
3.Aquatic habitats were characterized within the study zone for each fish
stream crossing.Habitat characteristics that were described included
stream width,depth;water velocity,flow,substrate composition and
availability of cover.Flow measurements on wadeable streams were made
at one location in the study reach using standard stream cross section
methods in conjunction with a Marsh-McBirney or Gurley current meter.
Habitat characteristics within the study reach were entered onto
standard data sheets (Appendix A).Three types of data sheets were used
for each stream:a cover sheet which includes general stream informa-
tion as well as discharge data,stream reach inventory sheets for each
study reach which include data specific to the reach,and fish data
sheets which include field data for fish captured.Stream habitat maps
were constructed for some of the streams to aid in future impact
analysis and final siting of road crossings.
Additional effort beyond that described above was spent on selected streams
where background information was lacking or where special needs were per-
ceived.This effort is described in the discussion for each stream.
Sampling Periods
The initial investigation occurred between the dates of August 16 -August
25,1983.It included three days of helicopter-based sampling and three days
of supplemental ground survey.
A boat-based investigation of the Little Susitna River oCGurred on September
13 and 14,1983.
A final study effort occurred on October 18 and 19,1983.It included one
,day of helicopter travel and one day of ground travel.This last study
period was initiated because of the addition of the Big Lake corridor.

C.HOUSTON CORRIDOR
The Houston corridor,along with stream crossing sites,is shown in Figure 1
and Plate 1.Aerial reconnaissance indicated that only two fish streams
cross the route.Two wetland swales contributing to a Goose Creek tributary
at the south end of the corridor were inspected on the ground as likely
stream locations;however,in both areas no defined channel existed and,
consequently,fish potential was assumed to be nil.
Hourglass Lake Drainage System
Background Information.This small stream flows from Hourglass Lake (with a
tributary from Colt Lake)southwest to the Little Susitna River (Plate 1).
Stream length including meanders was estimated from aerial photos at about 10
miles (16 km).No known biological research has been conducted on the
stream.However,Lebida (1983)investigated the coho salmon rearing poten-
tial"of Hourglass and Colt Lakes.Hourglass Lake was found to contain
juvenile coho salmon as 'well as rainbow trout,threespine stickleback,and
long nose suckers.All of the fish species in the Little Susitna River have
access to the stream.
Methods.Because of the lack of information available for this stream,three,
separate reaches were examined:at the proposed road crossing site,near
Hourglass Lake,and near the co~fluence with the Little Susitna River (Plate
1)•Aquatic habitat survey forms were completed for each reach and fish
populations were sampled.At the crossing site,a 100-foot (30-m)section of
stream was sampled using the backpack electroshocker.A block net was set at
the lower end of the reach and two passes were made working downstream with
the shocker.At the reach n~ar Hourglass Lake,stream depth and soft bottom
prevented instream sampling;therefore,shocking from the bank and visual
observations were relied upon to provide fish information.Stream depth
was also marginal at the lower study reach and instream shocking was not
effective.Three minnow traps were set overnight supplemented by visual
observations and shocking from the bank.

Results.Aquatic habitat surveys and fish data forms for the Hourglass
Lake drainage stream are provided in Appendix A.This low gradient stream
flows within a deep,incised channel that meanders through a continuous
wetland area.Discharge,measured at the crossing site,was about 2 cfs.
Substrate consists of sand and silt and aquatic vegetation is common covering
up to 90 percent of the bottom.The stream margin in most areas consists of
a sedge-shrub mat except at the extreme upper·end where the stream-flows
through a floating bog.Habitat is very uniform throughout the length of the
stream.Two beaver dams were present downstream from the crossing site
resul ting in short ponded areas.
Juvenile coho salmon were abundant throughout the stream.At the crossing
site 132 juvenile cohos from two length groups were caught in a 100-foot
(30-m)stream section.It was estimated that shocking was 60-80 percent
efficient;therefore,a conservative estimate of the number of cohos in fhe
study reach is about 170.Quantitative sampling was not possible at the
other two study reaches,but visual observations suggested that juvenile
salmonids were at least as abundant at the upper site as at the crossing
site.Abundance_at the lower study reach was probably somewhat lower.If it
is assumed that there were 170 cohos per 100 feet 00 m)and 10 miles (16 km)
of total stream,then-about 90,000 juvenile cohos were present in the stream •
The stream evidently provides excellent rearing habitat.
Two rainbow trout juveniles,several ninespine sticklebacks,and one
sculpin were also caught.The stream probabl y prov ides signi ficant rearing
habitat for rainbow trout from Hourglass Lake.
Project Implications.A culvert crossing of the Hourglass Lake drainage
stream appears practical due to the very flat terrain and low flow.However,
the stream is probably sensitive to disturbance for much of the year because
of juvenile salmon presence and the regulatory agencies may require mitiga-
tive construction procedures to protect downstream fish.The culvert will
have to be carefully designed and-placed to prov ide the low water velocity
required for young salmon.Crossing location is not critical because of very
uniform habitat in the corridor zone.

Little Susitna Riv~r
Background.The Little Susitna River is one of the most important streams in
the Matanuska-Susitna Borough from the standpoint of salmon production and
sport fishing use.The biology of the stream is relatively well known as a
consequence of several study programs initiated by ADF&G.All five species
of Pacific salmon are present in the Little Susitna River and all except
sockeye spawn in the main river (ADF&G 1982).Creel census studies and
escapement surveys of chinook and coho salmon have provided detailed infor-
mation on harvest and exploitation rates as well as population and age
structure for these species (Watsjold 1979,1980,1981;Bentz 1982).
Additional studies have been conducted on the early life history of chinook
and coho salmon in the river (Delaney and Wadman 1979).Chinook,coho and
pink.salmon spawn in the general area of the Houston corridor crossing (ADF&G
1982).and juvenile chinook a~d coho salmon use the area for rearing (Delaney
and Wadman 1979).
Methods.Because of the.extensive information on biological resources
available.for the Little Susitna River,a somewhat different approach was
taken during the investigation.Interviews with ADF&G personnel.suggested
that site specific habitat descriptions would be more useful than a detailed
biological study.Therefore,the primary effort was dedicated to habitat
mapping.An aerial photo enlargement at a scale of 1 inch equal 200 feet
was made for a 4-mile (6-km)section of river centered on the proposed
corridor crossing (Plate 1).A tracing of the river was made from the photo
and used as the basis for a habitat map.The entire study s~ction of the
river was floated in an inflatable raft,first on September 13 and again on
September 14.Habitat characteristics,particular!y depth and substrate,
were noted directl y on the tracing.Potential salmon spawning areas were
also noted on the basis of a subjective judgement of spawning suitability.
The field work was timed to correspond with coho salmon spawning,and obser-
vations of salmon .were noted on the habitat map.Stream reach inventory
sheets were not completed for the Little Susitna River.The habitat map was
considered to be a more useful format for describing stream conditions.

In addition t-8 the September mapping work,a visit to the river was also
made during the aerial survey on August 18,1983.At that time,a reach
about 1,500 feet (457 m)long was observed from the ground and selected slow
water areas were sampled for juvenile fish using the backpack electroshocker.
Results.During most of the September survey the water level was low
(discharge was 270 cfs)and visibility was very good.Poor weather and
increasing turbidity hampered the work somewhat on September 14 especially
late in the day.The habitat map (Figure 2)illustrates that the Little
Susitna within the study reach is a meandering river 50-90 feet (15-27 m)
wide with predominantly sand and gravel bottom.Significant pools were found
along the outside bank in most bend areas.Some of the pools were more than
7 feet (2 m)deep.Sand was a dominant substrate material and most gravel
substrates were imbedded to some degree in sand.Riffles (turbulent areas
with depth less than 1 foot [0.3 m])were not common at the time of observa-
tion but.would be much more prevalent at a lower water levet.
Coho salmon adults were observed throughout the study reach except at the
extreme west end (Figure 2).Thirty-five cohos were observed on September
,
13 and 22 were observed on September 14.Visibility was much better on
September 13 which undoubtedl y accounts for the higher number seen on that
date.Most adult cohos observed were single fish or paired fish and their
behavior suggested that they were in the early stages of spawning.Preferred
spawning areas appeared to be on medium gravels located on either the
upstream or downstream edge of a pool in water about 2 feet (0.6 m)deep.
Scattered potential spawning areas were found throughout the study reach
although most areas were small (Figure 2).
The electroshocker survey conducted on August 18 indicated that portions
of the stream margin were used as rearing habitat by juvenile coho and
chinook salmon.About ten cohos were caught for each chinook (Appendix A).
However,much of the stream was not suitable as rearing habitat and there
were few large areas of slackwater that would be preferred by young cohos.

The numerous deep pools would be expected to provide good resting habitat for
adult salmon as well as habitat for resident species such as trout.However,
resident fish appeared to be scarce during the September float trip.Onl y
two fish other than coho salmon were visually observed.Beach seining and
angling produced no fish.
Project Implications.·Location of the Little Susitna River bridge crossing
of the Houston corridor should be carefully considered both to avoid
impacting known spawning areas and to minimize overall disturbance to the
river.The river meanders widely in the corridor zone;therefore,the route
should be selected so that it infringes on the river at only one location and
crosses the river at a right angle.The stream habitat map (Figure 2)
should provide the information necessary to design a crossing with a minimum
of impact.
D.WASILLA/BIG LAKE CORRIDOR
The Wasilla/Big "Lake Corridor along with stream crossing sites is shown in
Figure 1.Because of uncertainty regarding corridor location,some streams
were observed at several locations.A total of seven streams were observed,
two of which were determined to be non-fish streams.
Mule Creek,
Background.Mule Creek is a small isolated stream that flows eastward into
Knik Arm (Plate 1).The stream has two forks which join together about
3/4 mile (1 km)from the stream mouth.No known physical or biological
information was available for the stream.
Methods.Three separate reaches of this stream were examined:at the mouth
where the stream traverses the bluff overlooking Knik Arm,the lower portion
on wooded upland terrain,and the upper portion where the stream follows a
wetland s\'lale.stream reach inventory sheets were completed for each reach.
Fish were sampled using the backpack electroshocker within the latter two
reaches.
1-11
Results.Mule Creek is a very small stream ranging in width from 3 to
15 feet (1 to 4.5 m)and having a discharge,at the time of observation,of
0.5 cfs.Two major kinds of stream habitats are present.The lower part of
the stream (east of the fork)is characterized by a shallow channel,moderate
gradient and gravel substrate with much overhanging woody vegetation.The
upper part of the stream is characterized by a narrow,relatively deep,
incised channel that flows through a grassy wetland.
Juvenile coho salmon were found in low density throughout the portions of the
stream that were sampled.The density was on the order of 1 coho per 25 feet
(8 m)of stream.Mule Creek is isolated from other stream systems;there-
fore,the presence of juvenile salmon suggests either that adults spawn in
the stream or that young coho entered the stream from Knik Arm.The former
explanation appears more plausible since the gradient of the stream near the
mouth appeared to be too high to allow access by small fish,except possibl y.
during extreme high tide.
Project Implications.A culvert appears to be a practical highway drainage
structure for Mule Creek.This very small stream contains salmon rearing
habitat and the culvert will have to be carefully placed to assure low water
velocity and minimize downstream impact.Culvert installation during the
period June 1 -August 1 would be adv isable to avoid disturbance 0 f spawning
salmon and incubating eggs.Mule Creek divides into two forks about 2/3 mile
(1 km)upstream from its mouth.Both forks would require adequate culverts
if the roadway were to cross above the split.
Unnamed Stream No.1
Background.This small stream.enters Knik Arm about 1.5 miles (2 km)north
.of Mule Creek (Plate 1).Its watershed is similar to that of Mule Creek.No
known physical or biological information was available for the stream.
Methods.One section of this stream was observed at the lower end during the
October survey.A stream reach inventory form was completed and fish were
sampled using the backpack electroshocker in a 300-foot (91-m)stream section.

Results.This very small stream is nearly hidden from view by vegetation.
It was not noticed during the summer survey when water levels were lower;
therefore,flow may have been much less in August and the stream may be
intermittant.No fish were observed in the stream and the value to fish
is considered to be marginal.However,the sampling occurred just prior to
freezeup and fish may have vacated the stream.Therefore,the possibility of
.6
fish entering from Knik Arm and using the stream as rearing habitat should
not be discarded completely.
Project Implications.A culvert would be a practical highway drainage
structure for this stream.Because of the possibility of fish use,the
slope and elevation of the culvert should match t~e natural stream to allow
passage.Special construction procedures or timing would probably not be
necessary.
Unnamed Stream No.2
Background.This very short stream flows eastward into Knik Arm about 1
mile (1.6 km)south of the southern margin of the Goose Bay flats (Plate
1).No physical or biological information was available for the stream.

At the level of the Wasilla corridor crossing,the stream channel becomes

Goose Creek
Background.Goose Creek is a small stream that originates at Stephan
and Sevenmile lakes and flows in a southerly direction through extensive
,wetland areas.It enters the Goose Bay State Game Refuge on its north side
and flows into Knik Arm at the mouth of the refuge area.The stream is about
8
9 miles (14.5 km)long,exclusive of meanders.
Some biological information was available for the stream.Adult and juvenile
coho salmon are known to be present as well as rainbow trout (ADF&G 1982;
Engle,pers.comm.).Coho salmon spawn within the stream between the Pt.
Mackenzie road and the Goose Bay refuge and rearing occurs in Stephan Lake
(ADF&G 1982).
Methods.Three reaches of lo~er Goose Creek were investigated on August 18
in relation to the proposed Wasilla corridor crossing.In addition,aerial
reconnaissance of upper Goose Creek and ground investigations of one more
reach was conducted on October 18 iIT relatirrnto the proposed Big Lake
corridor crossing.Stream reach inventory forms were completed for all
study reaches with a separate series of habitat survey forms completed for
each of the two sampling periods.Fish were sampled with the backpack
shocker at three of the four reaches,and at reach No.2 of the August
survey,a block net was utilized to trap downstream migrating sticklebacks.
Upper Goose Creek near the upper Big Lake corridor crossing·could not be
sampled during the fall survey because of very high water;water level was
over the banks and had flooded the adjoining wetlands.
Results.Goose Creek can be convenientl y divided into four sections of
similar habitat.The creek where it traverses the eastern portion of the
Goose Bay refuge,within the intertidal zone,can be considered poor fish
habitat because of the periodiC inflow of turbid water from Knik Arm and
heavy silt deposition.Within the western portion of the refuge,the stream
is characterized by a low gradient and incised channel and probably provides
fair to good rearing habitat for juvenile salmonids.North of the refuge for
about 2 miles (3 km),Goose Creek crosses wooded terrain with a higher

gradient and is characterized by some gravelly and 'rocky substrates and
alternating pools and riffles.Moderate numbers of juvenile rainbow trout
and a few coho salmon were found in this section.Coho salmon are also
reported to spawn in this general vicinity (ADF&G 1982).The balance of the
stream north of the Pt.Mackenzie road,traverses low gradient wetland
terrain and is characterized by a narrow,deep channel.This latter portion
is probably good coho salmon rearing habitat;however,the rearing capacity
was not confirmed during"this study since no sampling was done in the upper
reaches.
Very large numbers of young-of-the-year threespine sticklebacks were caught
in lower Goose Creek in August and were ev identl y migrating seaward.The
sticklebacks evidently spawn somewhere in the Goose Creek drainage.
Project Implications.A bridge or trestle crossing near the mouth of Goose
Creek would have little impact on the stream.Special precautions are
probably not necessary since the road corridor is in the intertidal zone and
the stream is subjected daily to wide fluctuation.in turbidity,depth and
salinity.
The .Big Lake corridor,as aligned in Figure 1,would cross the upper part of
Goose Creek in two locations.In both locations stream gradient is low and a
large culvert would probably be a practical drainage structure.Goose Creek
is a significant fish stream containing rearing habitat for coho salmon and
rainbow tr~ut and it provides a migratory corridor for young fish to Stephan
Lake.Therefore,the culverts would have to be carefully designed to provide
suitable velocity that would allow -passage of juvenile fish.Mitigation
measures may be required during construction to avoid downstream impacts from
dewatering and/or siltation.
Unnamed Stream No.3
Background.This very small stream enters the Goose Bay Flat from the north.
It crosses the existing Goose Bay road via a culvert near the abandoned Nike
missile site (Plate 1).No known physical or biological information was
available prior to this study.
1-15
Methods.A brief reconnaissance of this stream was conducted on August 24.
Aquatic habitat survey forms were completed and fish were sampled qualita-
tively using the backpack electroshocker at selected locations.
Results.The stream appears to drain wetland areas north of Goose Bay.The
Goose Bay road has interrupted the flow creating a pond about 1 acre (0.4 ha)
in size whiCh drains v ia a 24"cuI vert.At the time of the survey,the
culvert discharge was about 2.5 cfs.The pond water appeared stagnant and
may have been lacking in dissolved oxygen.Downstream from the culvert,the
stream channel was poorly defined flowing through a wetland area dominated by
grass and willow.The stream channel disappeared completely in the Goose Bay
flat.
No fish were observed or captured either above or below the road culvert and
the stream has little potential as fish habitat.
Project Implications.No "l?pecial precautions would be necessary to protect
fish resources in the event of a highway crossing of this stream.A culvert
installed using normal good construction practices would be adequate.
Fish Creek
Background.Fish Creek is a substantial stream that flows from Big Lake
southward into Knik Arm.The drainage system supports signi ficant fish
resources of value to both sport and commercial fishermen.In addition,
ADF&G operates a hatchery on Meadow Creek near Big Lake that produces coho
and sockeye salmon,some of which are released into the Fish Creek drainage.
The existence of these important resources within a heavily used recreation
area has -inspired research activity and consequent!y,the biology of Fish
Creek is relati~ely well known.All five species of Pacific salmon are
present in Fish Creek with king,coho and pink salmon spawning in the creek
(ADF&G 1982).Sockeye salmon spawn in lakes and streams upstream from Fish
Creek with Big Lake serv ing as a primary rearing area for both natural and
hatchery produced sockeyes.Subst.antial information is available on the
development and migration timing of salmon smoHs in Fish Creek (Chlupach
1982).

Resident fish species such as rainbow trout and Dolly Varden are also
present in Fish Creek.
Methods.Emphasis during the investigation was on site specific habitat
characteristics since fish distribution was already well known.A stream
reach about 2,000 feet (609 m)long was examined on August 24 and 25 in the
vicinity of the existing Knik Road crossing (Plate 1)since the proposed
Wasilla Corridor was planned to cross Fish Creek at or near this location.
Aquatic habitat survey forms were completed and enough information was
collected so that a habitat map could be drawn if needed.Selected stream
areas were sampled for fish using the backpack electroshocker.
After the Big Lake corridor was proposed,a second investigation was con-
ducted on October 18 to survey upper Fish Creek near the new crossing site
(Plate 1).A stream rea~h about 500 feet (152 m)long was examined and a
second set of aquatic habitat survey forms was completed.Again selected
stream areas were sampled,for fish using the backpack shocker.In addition,
an aerial survey of upper Fish Creek was conducted and the locations of
spawning salmon were noted.
Results.Lower Fish Creek above the intertidal zone appeared to be a
classical,moderate gradient stream with alternating pools and riffles except
in the vicinity of the Knik Road whe,re a substantial portion had been dis-
turbed by past and present roadway crossings.Substrate materials were
,predominantly gravel and cobble.Discharge at the time of the August survey
was about 99 cfs.Fish Creek crosses under the Knik Road via two 150-foot
(46-m)long,10-foot (3-m),diameter culverts,one set at a higher elevation
than the other to handle high water.Deep pools have formed at both the
inlet and outlet of the culvert.At the time of the survey all of the flow
was being carried by the lower culvert and water velocity was measured
throuqh the culvert at 7.8 ft/sec using the floating chip method.About 400
feet (122 m)below the Knik Road the character of Fish Creek changes because
of influence from tidal water,of Knik Arm.Gradient becomes reduced and
stream bottom and bank materials are dominated by glacial silt.The stream
widens near the mouth and depth varies with tide stage.
I-I?
Electroshocking upstream from the Knik Road indicated that juvenile salmonids
were common within selected slower water habitat areas.The fish were
dominated by coho salmon with smaller numbers of chinook salmon and rainbow
trout also observed.Juvenile salmon were also abundant along the fringes of
the plunge pool area below the culvert.Again cohos were the dominant
species but several chinooks were also caught.It appeared likely that the
concentration of young fish below the culvert was a result of the high water
velocity in the culvert;young fish may have been washed through the culvert
and then became trapped between the culvert on one end and the saltwater
influence of Knik Arm on the other.
The character of Fish Creek is somewhat different at the proposed Big Lake
corridor crossing.Gradient is less,width is greater and the substrate
is dominated by sand with patches of fine gravel.Aquatic vegetation covered
much of the stream bottom.The only salmonids captured with the shocker were
two juvenile coho salmon and one juvenile rainbow trout.The stream appeared
to provide good rearing habitat ~nd it is suspected that the low fish density
was a reflection of the time of year.The water temperature was only ZO'C and
most juvenile salmonids may have moved into Big Lake for the winter.The
aerial survey indicated that coho salmon spawn in the general vicinity of the
Big Lake corridor,but in very low density.Nine adult cohos were observed
on three redds within the 5 mile (8 km)stream section (Plate 1).Suitable
spawning habitat is widely scattered and limited to small patches of gravel.
Some of the better spawning habitat appeared to be located adjacent to the
knob-like hill just east of the study reach.
Project Implications.Fish Creek is important habitat from the standpoint of
rearing,spawning and migration.If development of the Wasilla corridor will
involve reconstruction of the existing Fish Creek crossing,then serious
consideration should be given 'to the use of a bridge rather than cuI verts.
The natural stream bed gradient is relatively steep which would make it
difficult to satisfy velocity criteria with a culvert,especially in a
stream as large as Fish Creek.Placement of a culvert at less than natural'
slope to achieve lower velocity would create problems downstream and step-
down s~ructures would probably be required in the stream below the culvert to
allow fish access to the culvert outlet.

A bridge would also be a preferred structure for upper Fish Creek at the
proposed Big Lake corridor crossing.Because of stream width and habitat
sensitivity at this location,culverts Mluld probably cause some adverse
impact.
Threemile Lake Inlet Streams
Background.Topographic maps indicate that two small streams enter Threemile
Lake,one at the extreme northwest corner of the lake and the other at the
southeast corner.The Big Lake corridor as shown on Figure 1 would cross the
former stream while a possible al ternative routing would be south of
Threemile Lake and thus would cross the latter stream.No known physical or
biological information was available for these streams.However,Threemile
Lake and its outlet stream (a tributary to Fish Creek)are known to contain
~/;
coho and sockeye salmon (ADF&G 1982).The lake presumably provides rearing
habitat for juveniles.
Methods.Aerial surveys were conducted of both inlet streams along with
brief ground surveys.Aquatic~habitat survey forms were completed for
the east inlet stream arid selected stream areas were-sampled for fish using
the backpack electroshocker.
Results.The west inlet stream is identifiable only intermittantly as it
flows through a narrow wetland adjoining the end of the lake.No consistent
stream channel exists and the stream has no fish potential.Survey sheets
were not completed and fish were not sampled.
The east inlet-stream is about 1.5 miles (2.5 km)long and contains several
beaver ponds.Discharge is less than 0.5 cfs and the stream is generall y
less than 1.5 feet (0.5 m)deep with a low gradient.The channel is well
defined in most areas with a muck bottom.Fish potential is probably limited
by the low flow and extensive beaver activity.Portions of the stream
appeared to be fair rearing habitat and it is likely that at least the lower
portion of the stream is utilized by juvenile salmonids during the summer.
No salmonids were observed during the October survey but the presence of
sculpins suggests that stream conditions would probably support juvenile
salmonids.

Methods.An aerial survey and ground investigation of one reach was con-
ducted on October 18.A second reach was observed on October 19 using
ground transportation.Aquatic habitat survey 'forms were completed and
selected areas were sampled for fish using the'electroshocker.
No fish were observed at the time of the survey.Since water.temperature was
near freezing and the stream margins were icing up,it is suspected that most
fish that reside in the creek during the s.ummer had vacated the area fer
wintering areas in Lucille or Big Lake.The same phenomenon was observed in
Goose Creek and upper Fish Creek during the October study period.
Results.Lucille Creek is in most areas a deep,narrow stream with abundant
aquatic vegetation.Discharge was about 12 cfs at the time of the survey.
Channel configuration and habitat value are uniform for most of the western
hal f of the stream.The stream appears to be very,good salmonid rearing
habitat;however,spawning potential is marginal with only a few patches of
gravel substrate noted in the study area.
Background.Lucille Creek originates at Lucille Lake,near Wasilla,and
flows westward for about 11 miles (18 km)until it joins Meadow Creek,a
tributary to Big Lake.Some biological information was available for the
creek prior to this study.Lucille Creek is known to provide rearing habitat
for coho salmon (ADF&G 1982).Sockeye salmon have also been observed in the
stream.Most of the fish species found in the Big Lake/Fish Creek drainage
would be expected to be present in Lucille Creek at some time.

protect downstream fish.A culvert across Lucille Creek would have to be
carefully designed to provide the low water velocity required for young
salmon.The crossing location should be selected to avoid stream segments
with higher than average gradients as typified by study reach No.2.

This study was initiated as part of a baseline data collection program
relating to environmental analysis of the proposed Knik Arm Crossing project.
The study identifies and evaluates terrestrial habitats within the proposed
highway approach corridors on the north side of Knik Arm in order to evaluate
impacts,select environmentally preferred highway alignments and comply with
Federal regulations protecting wetland habitats.
The U.S.Soil Conservation Serv ice (SCS)in conj unction with the Susitna
River Basin Cooperative Study Program (U.S.Dept.of Agriculture 1981),
previously mapped the study area according to vegetation and soil conditions.
These maps were at a scale of 1:63,360.In addition,the U.S.Fish &
Wildlife Service (FWS)mapped wetland areas,at the same scale,as part of
the National Wetlands Inventory Program.The FWS wetland maps use the
wetland classification system developed by Cowardin et ale (1979).Using the
above maps and associated field data,the FWS further evaluated major habitat
types according to their ability to provide life requisites for key wildli fe
species (U.S.Fish &Wildlife Service 1981).Habitat evaluations were
modelled and,with the help of a computer,habitat maps for key species were
generated as part of the analysis for the Willow subbasin report (U.S.Dept.
of Agriculture 1981).
The original SCS scale of 1:63,360 was considered too large to provide
adequate resolution for assessment of direct impacts from highway development
that might result from the Knik Arm Crossing Project.The existing
information base was expanded,therefore,mapping speci fie corridors at a
substantially smaller scale while using a methodology similar to that
employed previously.
B.METHODS
Probable road alignments within the alternative north approach corridors
were identified by project engineers (Plate 1).It was assumed that direct
impacts would be confined within a one-mile wide corridor centered on the
II-I
proposed alignments.Detailed habitat mapping was,therefore,prepared for
these one-mile zones.
Photomosaics of each corridor were constructed using true color aerial
photographs at a scale 0 f 1:12 ,000.These mosaics·formed the basis for all
subsequent mapping.
Vegetation
The vegetation of the road corridors was mapped using aerial photo interpre-
tation and classi fied according to the rev ised hierarchical classification
system of Viereck et ale (1982).The Viereck system was developed subsequent
to the original mapping effort of the SCS and provides a more useful tool for
delineating habitat values (USFWS 1981).Map units reflect the third level
of resolution of this classification scheme (Table 1).The units were
cross-checked against map units developed by SCS to insure consistency.
Infrared aerial photographs (scale 1:250,000)were also used to aid in
identification of vegetation types.Vegetation maps were prepared as
mylar overlays over the photomosaics.
A field survey of the routes was conducted by helicopter on August 2-5 and
September 20-21 for purposes of ground truthing habitat types.Selected
plant communities were observed on the ground and community composition was
noted.
Wetlands
Wetland areas were delineated within the study corridors reI ying heav il y
on the FWS \~etlands Inventory maps as the basis for determining wetland
boundaries.Since the mapping units for the Knik Arm Project are at a
smaller scale than the FWS maps,greater resolution was possible and modifi-
cations were made to the boundaries of some wetlands relative to the FWS
maps.However,for ·the most part,there was a high correlation between FWS
wetlands inventory maps and the more detailed maps prepared for the Knik Arm
north approach corridors.

Wetlands maps were prepared as a separate mylar overlay over the corridor
photomosaics.Map units represent three categories:streams and open
water,wetlands (all types combined),and non-wetlands or uplands.This
nomenclature corresponds to that of Cowardin et ale (1979).
Habitat Evaluation
Models of species-spec~fic habitat requirements have been constructed
for many of the major wildlife species in Alaska using all the pertinent
published and unpublished data on these species (U.S.Fish &Wildlife Service
1980).These models rank habitats according to their ability to provide life
requisites for these species.The FWS applied these models to the vegetation
data collected by the SCS for the Willow subbasin (translated into the
Viereck classi fication system)and ranked habitats in the study area
according to suitability for five species;moose,snowshoe hare,willow
ptarmigan,red squirrel and spruce grouse.D~gitized maps,with the minimum
map unit size of 10 acres,were developed and are presented in the final
Willow subbasin report (U .5.Dept.of Agriculture 1981).The same metho-
dology was used in evaluatinq the vegetation categories delineated within
each road corridor (except that wiilow ptarmigan was deleted as a key
species).Life requisite categories by habitat type for the key species are
given in-Table 2.The wildlife habitat values expressed in Table 2 were
illustrated on a mylar overlay for use with the corridor photomosaics.
C.RESULTS
The results of the habitat mapping consist ~f a series of aerial photomosaic
strips each representing a one-mile wide corridor centered on the proposed
al ternative road alignments as presented on Plate 1.Three transparent·
overlays were prepared for each photomosaic:(1)vegetation types,(2)
wetlands and open water habitats,and (3)wildlife habitats.
These maps are available for viewing on request from the Knik Arm Crossing
Project office (907/278-1565)or by contacting the Alaska Department of
Transportation and Public Facilities.
