EXPLANATION OF SUPPLEMENT
The Access Planning Study was published in January of 1982.It
contained a detailed discussion and cost estimate for eleven
different proposed access routes to the Susitna Hydroelectric
Project.In March of 1982 the Susitna Hydroelectric Feasibility
Report was presented by the Alas ka Power Authority to the publ ic
resou rce agencies and organizations.The report recommended an
access plan which for reasons of project schedule,would have
necessitated the construction of a pioneer road prior to the FERC
license being issued.The construction of a pioneer road,
however,was considered unacceptable by the resource agencies
and the plan was discarded.Consequently a further study was
initiated in which,the evaluation criteria were refined and an
additional seven alternative plans developed.One of the main
issues that affected the selection and development process was the
elimination of any pre-license construction.I n order to meet the
overall project scheduling requirements this constraint makes it
necessary to secure initial access to the Watana damsite within one
year of the FERC license being issued.Amongst the other
important issues considered was the desire of Native organizations
to have access to thei r lands expecially those to the south of the
Susitna River,and the objective of minimizing environmental
impacts.
Subsequent to the Access Planning Study of January 1982 being
published the locations of the construction camps were finalized;
the Watana camp being north of the Susitna River and the Devil
Canyon Camp to the south.The change in camp location slightly
modified the lengths of the road segments,but considering the
samll difference,Plans One th rough Eleven were not revised.

Supplement
Throughout the studies conducted subsequent to the Feasibility
Report of March 1982 numerous comments have been received from
interested agencies,groups and individuals.These include State
resource agencies,environmental groups,local communities,Native
organizations,The Alaska Power Authority and Acres American
I nco together with their specialist subconsultants.As a result of
this comment and exchange of information,the seven new access
plan represent a more coordinated compromise among the interested
groups.
The new plans,for the most part,follow segments·discussed in
the original report.This supplement covers the new plans by
supplementing the original report where needed.The major items
found in this supplement are:
1.Additional segments needed for new plans discussed
(Chapter Nine).
2.New plans discussed (Chapter Ten).
3.Segment,Terrain Unit,and Environmental Concerns
maps in Appendices updated to show new routes.
4.Cost estimates generated for new plans (Appendix F).
5.Plan Eleven has been revised to include a low level
crossing at Devil Canyon for access to the camp on
the south side.It is now Plan 11 R.
I n order not to change the page numbering of the enti re report,
the following numbering policy has been used:

Plan 11
Plan 11 was revised to Plan 11R to provide access to the camp on
the south side of Devil Canyon.
Plan 11R supercedes Plan 11.Plan 11R serves the enti re project
from the Denali Highway.No access is provided at Gold Creek.
Supplies are shipped by rail to a railhead at Cantwell,then
trucked to Watana via the Denali Highway,then on to Devil
Canyon along the north side.Access to the South side of the
damsite is via a low level crossing similar to the one found in
Plan 5.This plan has the advantage of a low risk of schedule
delay.The longer haul,however,makes this route the most
expensive from a logistics standpoint.
Plans 12-18
These plans use modifications of the 3 basic corridor routes used
in Plans 1-11.
Plan 12 is an all road,north side route that avoids the undesirable
Portage Creek traverse by crossing at the mouth of Portage
Creek.A low level crossing of the Susitna river is included at
Devil Canyon.The road is served by railhead from Hu rricane.
The disadvantage of this plan is the major bridge and associated
.schedule delay at Portage Creek.
Plan 13 is all road,with direct access from the Alaska Railroad
and Parks Highway at Hurricane,to the Watana Damsite,via a
pass near the upper end of Portage Creek.A branch road serves
the Devil Canyon Damsite,crossing the Susitan River near Portage
Creek.
r35/a12 2-9A
Supplement
Plan 14 is a combination of road and rail.Rail is extended from
Gold Creek north to a railhead on a terrace,on the Susitna River.
From here,road continues to both damsites on the south side of
the Susitna river,crossing to the north side near Fog Creek.
Access to the Parks Highway is provided by a road spur from the
railhead north to Hurricane.
Plan 15 is the same as Plan 14,but deletes the road link to the
Parks Highway.This lowers the construction cost and effectively
eliminates public access.
Plan 16 consists of a railhead at Gold Creek,road to Devil
Canyon,road from Devil Canyon to Watana,'and a public access
road from Hurricane to Devil Canyon.The road from Devil
Canyon to Watana is on the south side to Fog Creek,then crosses
the Susitna to join the camp on the north side.
Plan 17 is similar Plan 6,except that,instead of a service road on
the north side,this plan has a service road that is on the south
side between Devil Canyon and Fog Creek,then crosses to the
northside to reach Watana.As with Plan 6,Devil Canyon is
served by rail and Watana by road from the Denali Highway.
Railheads are located at both Devil Canyon and Cantwell.
Plan 17A is a slight modification of Plan 17.From Fog Creek to
Watana Dam,the road stays on the south side of the river.
Plan 18 is another modification of Plan 6. It includes rail access
from Gold Creek to Devil Canyon,road access from the Denali
Highway to Watana,and a service road between the dams on the
north side.Plan 18 differs from Plan 6 in that Devil Canyon is
crossed by a high level bridge,and the alignment has been
improved.

CORRIDOR SELECTION
Deiscussion of Alternate Segments
Supplement
Supplement
(fa)Segment l-G
(i)Description
Segment l-G is an alternate to a portion of l-A from the
Parks Highway to Chulitna Pass.Unlike segments l-A and
l-F,this segment avoids Denali State Park lands and the
recently su rveyed I ndian River Subdivision.The segment
passes Chulitna Butte on the east side,follows the base of
the mountains,and joins the highway and railroad at
Hurricane.See Figure 9.2A
This segment is six miles long.
(ii)Line and Grade
This segment conforms with the preferred design parameters.
Though longer than the portion of l-A it replaces,the line
and grade are comparable.
(iii)Drainage Features
A number of small drainages are crossed on this segment.
All can be easily crossed with culverts except Granite
Creek,which may require a pipe arch or small bridge.
(tv)Bridges
No bridges will be required other than the possible short
span at Granite Creek,just east of the Hurricane Siding.
r35/a15 9-16A
Supplement
(v)Soils
By traversing the base of the mountains east of Chulitna
Butte,this segment avoids the extensive organics
encountered in l-A.Terrain unit mapping is not yet
available in this area,however,the steeper slope and better
drainage definition would suggest more manageable soils.
(vi)Envi ronmental Concerns
A final analysis of environmental impacts for this segment
have not yet been received.The segment does alleviate the
problems created by l-A.Segment l-G will avoid the
wetlands encountered in l-A,ci rcumnavigate the existing
cabins in Chulitna Pass,and away from the State lands that
have been designated Denali State Park or Indian River
Subdivision.
(vii)Segment Suitability
Segment l-G appears to be a superior choice to the portion
of Segment l-A in the Chulitna Pass area.This cannot be
confirmed,however,until aerial photography,terrain unit
maps,and environmental maps are generated.

to Watana Damsite,but does
Canyon Damsite.The segment
Figure 9.2A.
(ii)Line and Grade
Grades will be in excess of the desired parameters.An 8%
grade wi II be needed for one to two miles.
(iii)Drainage Features
The segment traverses a steep slope above a tributary of
Portage Creek.Care must be taken to control side hill
erosion as Portage Creek is an anadromous stream and the
tributary paralleled may also be.No other significant
drainages are encountered.
(iv)Bridges
Portage Creek will be crossed just upstream of the crossing
anticipated for 1-A.The same class of bridge -approx-
imately 200 feet long with two or th ree spans -should be
s uffi ci ent.
(v)Soils
This segment crosses frozen basal till in the relatively flat
r35/a17 9-16D
Supplement
Portage Creek Valley,colluvium over bedrock and exposed
bedrock along the steep side slopes of the Portage Creek
tributary,and frozen basal till along the gentler drainage
into Devil Creek.Problems with erosion and thaw settlement
will be similar to those encountered in Portage Valley on
1-A.
(vi)Environmental Concerns
The major envi ronmental impact anticipated is on the possibly
anadromous tributary of Portage Creek that the route will
parallel.
By shortening the route to Watana Damsite and removing the
loop of road that serves Devil Canyon Damsite,this segment
alleviates several major en vi ronmental concerns.There
would be less impact on Portage Creek because only one side
of the valley would be traversed.The valley is a fu r
bearer habitat and salmon spawning area.Also avoided is
the potential raptor habitat in the Devil Canyon and Portage
Creek confluence,and the fur bearer habitat and lodge at
High Lake.
(vii)Segment Suitability
This segment's suitability is dependent on several criteria.
The grade is above the desireable 6%,but only for a short
distance.When joined with 1-A,Devil Canyon is bypassed,
which will necessitate a separate spur road be built for the
Devil Cayon Dam Construction and access.The original
r35/a18
9-16E
,
Supplement
Segment l-A traversed both sides of Portage Creek,which
was considered to be an unsuitably high environmental
impact.By limiting the traverse to only one side,the
combination of Segments 'l-A and l-H becomes suitable.
r35/a19 9-16F
Supplement
(ua)Segment 2-Q
(j)Description
This segment joins 2-1 to 2-B.Presently,2-1 ends at Devil
Canyon and 2-B starts there.Segment 2-Q would start on
2-1 about 2 miles before the damsite,traverse Chechako
Creek and its major tributary at their upstream reaches,and
join 2-B about four miles southeast of the damsite.See
Figure 9.8A.
This segment is nine miles long.
(ll)Line and Grade
This segment substitutes a longer route,with maximum
grades and minimum radius curves for the major bridges
required on 2-B.By starting south several miles west of
Devil Canyon Damsite,the unacceptably high grades found
in 2-B can be avoided.
(iii)Drainage Features
As with 2-B,the alignment is on high ground and avoids
most drainage conflicts.

(iv)Bridges
Because Chechako Creek and its tributary are crossed well
upstream of 2-B,the gorges are much smaller.Smaller,
conventional bridges can be used.
(v)Soils
The segment traverse colluvium over bedrock and exposed
bedrock.Some patches of solifluction are in the vicinity,
but can be avoided.No significant probelms are foreseen.
(vi)Environmental Concerns
This segment may enter into the caribou wintering areas at
the upper reaches of Chechako Creek.No other significant
concerns have been noted.When used in conjunction with.
2-B,as a substitute for 2-G,a raptor nesting area is
avoided.
(vii)Segment Suitability
This segment combined with the east part of Segment 2-B,
appears to be equally as suitable as Segment 2-G.Though
it lengthens the total mileage to Watana Damsite,it eliminates
the problems associated with the high bridges at Chechako
Creek and neighboring gorges,extensive rock excavation,
and possible construction delays.

(wa)Segment 2- RRR
(i)Description
This segment is a seven mile spur of railroad that leaves the
existing tracks at Gold Creek,traverses the bluffs on the
south side of the Susitna River,and ends in a railhead on a
flat terrace on the south ban k of the S usitna River.See
Figure 9.10A
(Il)Line and Grades
By sidehill cutting into the Susitna River bluffs,the railroad
remains at a low elevation with a relatively flat grade.
Minimum radius curves will be needed to conform to the bluff
as much as possible.
(iii)Drainage Features
Gold Creek and several minor unnamed drainages can be
crossed with cu Iverts.

which has a relatively low slope stability.Bin walls or other
soil reinforcement may be needed.The terrace and flood
plain soils encountered in the beginning and end of the
segment should pose no special problems.
(vi)Environmental Concerns
Both 2-RR and 2-1 parallel this segment.No environmental
conflicts were found when reviewing them.
(vii)Segment Suitability
This segment of railroad would be suitable to use in
conjunction with a road that continues on to Devil Canyon
(such as 2-1).It effectively eliminates all public access
from the Gold Creek vicinity.It also precludes the use of
segments 2L,2H and 2K due to conflicting grades.
(wb)Segment 2S
(i)Description
This segment connects segment 2A in the Stephan Lake
vicinity with Segment lC by crossing the Susitna River.
See Figure 9.10B.The segment is seven miles long.
(ii)Line and Grade

Supplement
banks of the Susitna River.The banks lie at 50 to 100%
cross slopes,with exposed bedrock in some places on the
south bank.
(iii)Drainage Features
On the south side of Susitna River,several small drainages
are crossed for which culverts should be adquate.
(iv)Bridges
The Susitna River bridge will be a major high level span,
with approximately 600 feet of steel truss and 2600 feet of
plate girder,and over 100 feet above the present water
surface.The height is necessary in order to span the
future Devil Canyon Reservoir.During initial road
construction,there would be sufficient room to construct a
road to the bottom of the valley for a temporary low level
crossing or ferry.This would speed bridge construction
and avoid access delays to the Watana Damsite.
(v)Soils
The segment is largely on frozen basal till,similar to those
discussed in other sections of this report.
(vi)Environmental Concerns
This area has not been studied in detail from an environ-
r35/a24 9-52D
Supplement
mental standpoint.Previous overviews of the area did not
reveal any conflicts.
(vii)Segment Suitability
Segment l-C has been deemed unsuitable for construction,
alignment,and envi ronmental reasons .However,the small
piece that joins Segment 2-S to Watana Dam appears
satisfactory.Segment 2-S itself is within acceptable design
parameters and is deemed suitable for further consideration.
(we)Segment 2-T
(i)Description
Segment 2-T connects 1-A just east of I ndian River with
Segment 2-1.Included in this segment is a major bridge
across the Susitna River.The segment is seven miles long.
See Figure 9.10B.
(ii)Line and Grade
The north bluff of the Susitna River will have to be side hill
traversed at a maximum grade.The rest of the segment is
made up of milder grades and few curves.
(iii)Drainage Features
Only minor drainages are crossed,which can be suitably
r35/a25 9-52E
Supplement
crossed with culverts.
(tv)Bridges
The bridge across the Susitna River will be similar to the one
anticipated in 2-E,a 2480-foot,orthotropic steel structure with
approximately twelve spans.
(v)Soils
This segment travels across frozen basal till interspersed
with patches of organics.The frozen basal till should not
be a significant problem over the majority of the route,since
the cross slope is slight.The potential for erosion and
slope failure will be as high on the Susitna River north
bluff,as it is on the south bluff (see Segment 2-R,2-1 and
2-RRR)
(vi)Environmental Concerns
A detailed study was made of the environmental concerns in
this area has not yet been completed.If this segment is
used as a substitute for 2L or 2E,the major impact of road
access to the Indian River Remote Parcel sites would be
removed.
(vii)Segment Suitability
This segment is suitable for roadway construction and

Segment 2-U shortens the 1-A segment by eliminating the
loop up Portage Creek.Instead,the segment crosses
Portage Creek at its confluence with the Susitna River,then
rejoins 1-A above Devil Canyon Damsite.See Figure 9.10B.
This segment is six miles long.
(ll)Line and Grade
The portion of this segment just before and after the
Portage Creek crossing has to traverse steep (50%or higher)
sidehills,but all curves and grades are within the design
criteria.
(iii)Drainage Features
The major drainage -Portage Creek - will be crossed with a
bridge.Of the other more minor drainages,one that drains
a swampy area will be difficult as the entire valley that
contains it is lined with organics.This and other drainages
should be possible to cross with culverts.(iv)Bridges
r35/a27
9-52G
Supplement
A major bridge is required across Portage Creek.It will be
1100 feet long,and cable stayed.
(v)Soils
The segment goes th rough several unavoidable areas of
organics.The rest of the segment is on frozen basal till
with some colluvium and exposed bedrock at the Portage
Creek crossing.Construction will be similar to other areas
with these materials.
(vi)Environmental Concerns
This segment deletes the long "traverse up and down Portage.
Creek,thus avoiding impacts to salmon spawning areas ,fur
bearing habitat and a mining claim.The potential raptor
nesting area,however,is still impacted.Also subject to
possible impact is a historical site at the mouth of Portage
Creek.It consists of an inscription,dated 1897,with the
names of William Dickey and th ree other individuals.Dickey
was one of the first white men in the region.It is not yet
known if this site is eligible to be listed on the National
Register of Historic Places.Actual construction of the
Portage Creek bridge would require mitigation measures to
prevent erosion into salmon spawning areas.Long-term
erosion associated with segment 'l-A is not anticipated.
(vii)Segment Suitability
This segment eliminates the less desirable portion of
Segment l-A,with its difficult side hill construction and

environmental impacts.The trade off is a major bridge at
the mouth of Portage Creek that would impact the
construction schedule by requiring two or more years to
construct.
(we)Segment 2-V
(i)Description
Segment 2-V is a variation of 2-U.It branches off just
before 2-U crosses Portage Creek.Segment 2-V instead
crosses the Susitna River,and proceeds to the Devil Canyon
Damsite along the south side of the river where it joins line
2-1.This segment is fou rrniles long.See Figure 9.10B.
(Il)Line and Grade
Maximum allowable grades and minimum curvatures are used
on this segment,but it stays within the design criteria.
(iii)Drainage Features
Several ravines are crossed on the s »uth side of Devil
Canyon.Though they drain fairly small areas,the deepness
of the gorges may indicate that short bridges would be
cheaper than culverts under massive fills.

(iv)Bridges
In addition to the short bridges mentioned above,a major
bridge will be needed across the Susitna River.It would be
a steel deck truss,1100 feet long.
(v)Soils
The problems associated with these soils -frozen basal ti II,
with colluvium on the steep slopes -are as discussed else
where (see Segments 2-RRR in this supplement and
Segment 1-A in the main report).
(vi)Environmental Impacts
The only impacts noted for this segment are on the potential
raptor nesting areas found within Devil Canyon.

Supplement
(za)Segment 3-D
(i)Description
The short segment starts at Line 3A near Big Lake,passes
west of Deadman Mountain,and then joins Line 3C.While it
shortens the overall length of road from the Denali Highway
to Watana,it involves more difficult terrain.See
Figure 9.11A.The line is eigtht and one half miles long.
(ii)Line and Grade
Maximum grade would be utilized over most of the length of
this segment,in order to clear the pass between Deadman
Mountain and the mountains to the west.
(iii)Drainage Feature
The line parallels a marshy tributary of Deadman Creek
south of the pass.Several side branches would be crossed
with culverts.North of the pass,the headwaters of
Deadman Creek are paralleled,and crossed just before
joining Line 3C.This crossing would also be via culverts.

(vii)Segment Suitability
Though the segment is less desi rable from an engineering
and construction point of view,because of its steeper
terrain,it is more favorable from an environmental
standpoint and should be considered a viable alternative.

(i)Description
This seqrnert generally parallels Segment 3-D,but is 1 mile
west and traverses higher ground.The segment starts its
one mile offset near Tsusena Butte and rejoins Segment 3-D
at the pass west of Deadman Mountain.The length is

(ii)Line and Grade
Segment 3E is longer than 3D,has longer stretches of
maximum grade,and has a 180

it crosses a tributary of Deadman Creek.
(iii)Drainage Features
Generally,the same streams are crossed as in 3D,but they
are crossed at a higher (upstream)elevation.
(iv)Bridges
No bridges will be needed on this segment.
Iv)Soils
No data available yet.
(vi)Environmental Concerns
A detailed environmental study of the area west of Deadman
Mountain has not yet been completed,but it appears that
this segment is more favorable from an impact standpoint.
The road would be farther away from Deadman Creek,its
tributaries and associated wetlands,thereby mitigating to
some extent secondary impacts on waterfowl and grayling.
The route also avoids the cultural resource areas around
Deadman Lake and Big Lake.

Supplement
(viii)Segment Suitability
This route is within the minimum design standards,but has
more difficult terrain,higher elevation,and longer length
than other alternatives.The higher construction costs,
construction time scheduling and maintenance costs are offset
by the lower environmental impacts,making this segment a
viable alternative to 3D.

9.4 Corridor Summary -Supplement
Plans 1 to 11 R are very simple to arrange,with only one set of
sections selected for each of the three main corridors.Plans 12 to
HA,however,do not fit into this same pattern.Several different
sections in each corridor were considered of equal merit for
further investigation and 'incorporation into plans.For clarity,
the breakdown of segments,sections and corridors is resummarized
on Table 9.4,according to the following system of ranking.
1.Corridor -denotes a wide band.The th ree corridors
are #1 (north of Susitna River),#2 (South of
Corridor #1)and #3 (Denali Highway to Watana).All
study was conducted within the three proposed
corridors.
2.Segment - a proposed length of road or rail that may
or may not be suitable for fu rther consideration.
Some segments,such as 1-A stretch the entire length
of a corridor,while others are much shorter pieces.
Segments are not necessarily used in their entirety,
they may be superceded at one or more places by
other,more feasible,segments.
3.Section - a combination of one or more segments or
pieces of segments found to be suitable for incorpora-
tion into plans.
4.Plan - a combination of one or more sections to make
a complete road and/or rail facility that can serve
both dams.

Avoids major problems associated with the south route
between dams.Major bridges at Chechako Creek and Fog
Creek,heavy rock excavation and massive ice are all avoided
on this variation of the southern route.The road
construction is such that resupply can be achieved after the
first season,however,there would be some risk of schedule
delay.

tages of Plan 14,with the following exceptions:
o
o
o
(p)Plan 16
No access to the public.
Lower cost due to deletion of construction of
about 15 miles of road.
No impact on the Chulitna Pass existing
community in the Chulitna Pass area.
(i)Description
This plan serves Devil Canyon by road from a railhead at
Gold Creek.Watana is served by a road between the dams,

mostly on the south side of the river.In addition,there is
a road from Hurricane to Devil Canyon.This road is for
passenger vehicle traffic and truck transport if necessary.
(il)Seaport
Common to all plans are Anchorage and Whittier.
(iii)Modal Split
Freight is hauled from seaport to Gold Creek by rail,then
by truck to Devil Canyon and Watana.Passenger vehicles
use the road from Hurricane to Devil Canyon.
(iv)Sections Included
Plan 16 includes road Sections B-2 and B-6 to the dam sites,
and road Section A-8 to connect to the public road system.
There is a railhead at Gold Creek.

(viii)Advantages/Disadvantages
This plan has the same advantages and disadvantages of
Plan 14,except that the bridge over the Susitna River,for
Plan 16,is cheaper and will therefore lower the overall
construction cost,and the small section of rail (R-3)is
replaced with a road that would be easier to keep on
schedule.
(q)Plan 17
(i)Description
Plan 17 is similar to Plan 4,but with a service road mostly
on the southside.The service road would be on the south
side from Devil Canyon to just downstream of Fog Creek,
then would cross the Susitna River and follow the north
ban k to Watana.Devil Canyon is served by rail from Gold
Creek.Watana is served by road from the Denali Highway.
(ii)Seaports
Common to all plans are Anchorage and Whittier.

The risk of schedule delay is low,therefore this plan has
the highest probability of being completed within one
construction season.

Supplement
The railroad and service road have areas of difficult
construction,with major bridges,but that part of the
construction is not necessary until the Devil Canyon Dam
stage.
(viii)Advantages/Disadvantages
o
o
o
(r )Plan 17A
No public access to Devil Canyon;rail shuttle
needed for personnel.
Direct access between dams for maintenance and
operations staff.
Increased public access to the area south of
Denali Highway with associated negative
envi ronmental impacts.
rn Description
Plan 17A varies from Plan 17 only in the last few miles of
the east end of the maintenance road.I nstead of crossing
the Susitna at Fog Creek,the road continues on the south
side to Watana,and crosses the dam crest.
(ii)Seaports
Common to all plan are Anchorage and Whittier.

(s)Plan 18
Increased access to the native-owned lands in
the Fog Creek area which although meeting the
preference of Native organizations would
introduce di rect envi ronmental impacts.
All other advantages and disadvantages are as
per Plan 17.
(i)Description
Plan 18 varies from Plan 6 only in the way it crosses Devil
Canyon.The service road between the dams,on the north
side,crosses Devil Canyon with a high suspension bridge
downstream from the dam.As with Plan 6,Devil Canyon
Dam is served by rail from Gold Creek,and Watana Dam is
served by road from the Denali Highway.
