1. 0 lftiODUCTIOI
The Alaska Power Authority has proposed the construction of a two-dam
hydroelectric project on the Sueitna River. Project planning has been
separated by the Power Authority into the following time periods:
o Existing Conditions
o With-Watana Daa Only
Construction phase
Operation of Watana
o With-Watana aad Devil Canyon Da ..
Construction of Devil Canyon Da• and operation of Watana Da•
Operation of Watana and Devil Canyon D .. •
The construction and operation of these hydroelectric facilities are
expected to alter the natural habitat conditione currently utilized by fish
in the vari~u• aquatic habitat types present. Monitorina the critical water
quality paraMtere of the aquatic eovironMnt in each of these periods is
therefore oece .. ary. Prior to initiation of project construction,
.onitorioa of exietina conditione is necessary to eetablith baseline
conditione. Ooc:e construction beaine. .onitorina will be nece .. ary to
verify the accuracy of preproject projections and de~er•ine the dearee of
chana• that occurs. If chana•• in .. ter quality affect fish resources, they
will be addressed throuab the .itiaation plannioa process.
Aquatic .onitorina for this project has been divided into two broad
cateaoriea by the Power Authority:
430775
860327

o Construction monitoring and regulatory compliance
o Long-term monitoring
Thi• report describes the water quality element of the long-term monitoring
proaraa. The Power Authority draft Aquatic Monitoring Plan outlines the
proaraa approach for the construction monitoring and the other elements of
the lona-tera aonitorina plan. The general approach to long-term monitoring
taken by the Power Authority is to monitor na .tural conditions for several
year• prior to daa con•truction with the duration of time and data
requirement• dependent upon the paraaeter or •ituation to be monitored.
Water quality condition• will al•o be aonitored after Watana Daa
con•truction beain• and will continue throuah the initial years of Devil
Canyon o .. operation. The natural and with-project infor .. tion will then be
coapared to deteraine if •ianificant iapact• have occurred.
In 1985. the Power Authority. in cooperation with the Ala1ka Departaent of
Fi•h and G ... (ADPIG). beaan the lona-tera water quality monitorina prograa.
The para .. tera choaen for aonitorina included water teaperature 1 turbidity,
auapended aedi .. nt. aettleable aolida. total diaaolved aa•. di••olved oxyaen
and pB. Theae para .. tera are conaidered aood indicator• of chanae (for the
ayatea) and are readily aeaaured and analyaed. Other water quality
paraaetera (heavy •tala and oraanic nitroaen and phoaphorua) included in
the lona-tera aonitorina plan were not aaapled in the 1985 f i eld aeaaon. but
will be prior to the initiation of project conatruction.

The objective of thh aonitorina is to coapile a pre-and with-project

3 .1 SURFACE WATER TEMPERATURE
Surface water teaperature data were taken at seven aitea in the .. in channel
Suaitna River. Theae aitea were reatricted to .the reach of river extendina
froa the Parka Hiahway Bridae (RM 86.2) upatreaa to the propoaed Watana Daa
aite (RM 184.2). The location of theae aitea are preaented in Table 1 and
illustrated on Fiaure 1 and Appendix Fiaurea 1-8. Each teaperature atation
waa placed in a location conaidered to be repreaentative of the .. in flow of
the Suaitna liver. Several of theae site• were included in previoua
teaperature atudiea (~eklak and Quane 1985; lteklak and Quane 1984; ADF&G
1983; ADF6G 1981).
Surface wter teaperature •• continuously rec~rded uaina O.idata
International aodel DP2321 two channel Datapod teaperature recorder•. Both
channel• (a and b) were uaed to prevent aapa in the data that could reault
froa th~ failure of a channel to record. Ryan theraoarapha were also used
as "backup" units to further avoid data aapa.
The teaperature data collected by ~he Datapoda are recorded on an electronic
aeaory chip referred to aa a data atoraae aodule (DSM). The Datapod
aeaaurea the inatantaneoua wter teaperature every five ainutea and recorda
the aini .. , aean, and •xiaua water teaperaturea for each aix-hour
interval. The accuracy of the Datapod ia atated by the .. nufacturer to be

Turbidity vaa •••ured at aia aitea on the •inatea Suaitna River between

Total di .. olved ps aeasureaenta were taken at four sites in the Suaitna

The water teaperature aonitorins results are presented in Appendix Tables
1-7. Daily ain~ua. aean. and aaxiaua plots of these data are presented in
Appendix Fisures 9-15.
Water teaperaturea aaona the seven .onitorina stations in the study area
were found to exhibit siailar seasonal trends (Fiaure 2). Generally. water
teaperature increased in June. reached aax~ua teaperaturea in July. and
subsequently decreased throuah the reaainder of the a.-r • droppins to
freeaina or near freeaina teaperatures ~Y aid-October.
In the au..er .ontha (June throuah Auaust). the re•ulta show that the river
waraed aliahtly between the Watana Daa site and Talkeetna. At Talkeetna and
as far upatreaa as Curry Station. seasonal aax~ua water teaperatures occur-
red one day earlier than the occurrence of aaxiaua water teaperaturea up-
atreaa at the Gold Creek. Lll 53. Devil canyon. and Watana stations (July 18

At the Parke Riahway lridae Station, turbidity wae coneietently hiaher than

leveh obtained for the weekly echedule (riaure 5). The difference in

araph reveals that suapended solid• concentration• were fairly uniform in
the Suaitna liver between Talkeetna and Devil Canyon and concentrations were
conaiatently hiaher at the Parka Biahway Bridae Station.
Settleable solids raqed fora 2 to 351 111/l in the lliddle reach and 37 to
331 111/l at the Parka Biahway Bridae Station., AI with suspended solids,
there vaa little difference in settleable solid• amana station• upstream of
Talkeetna (Fiaure 7). Concentration• of settleable solid• were aenerally
hiaher at the Parka Biahway Bridae, but unlike suapended solid•, •:dmua
aettleable aolide concentration• •aaured at the Parka Biahway Bridae did
not exceed aaxiaua concentration• at the Gold Creek Station. Also, peak
concentration• at Parka Biahway Bridae (aa determined by weekly
obaervationl) occurred later for eettleable than suspended solids. The
reaeon for thie ie not clear but aay be a reault of local climatic
conditione, particularly thoee that occurred in the Chulitna liver drainaae
(pera. coaa; Jaaee Knott USGS). Overall, eedi .. nt concentrations were found
to be auch areater at the Parke Biahway Bridae due to the sediment
contribution of the Chulitna liver. It hal been estiuted from sediaent
data collected by the USGS duriq 1982 and 1983 that the Chulitna liver
contribute• 65 percent of the approxi-tely 14 llillion ton• of sediment
pauiq the Parke Biabway Bridae Station (Lipecoab and Knott, 1985). The
Suaitna liver val found to contribute 24 percent and the Talkeetna River 10
percent.
A reareuion analyeil for aettleable va. suapended solid• (riaure 8) and
turbidity ve. euapended eolide (riaure 9) yielded fairly aood relationship•
(r2-o.95 for eettleable ve. euepended aolide; r 2 •0.96 for turbidity va.
