Anchorage,Alaska PREFACE This report is one of a series of reports prepared for the Alaska Power Authority (APA)by the Alaska Department of Fish and Game (ADF&G)to provide information to be used in evaluating the feasibility of the proposed Susitna Hydroelectric Project.The ADF&G Susitna Hydro Aquatic Studies program was initiated in November 1980.The five year study program was divided into three study sections:Adult Anadromous Fish Studies (AA),Resident and Juvenile Anadromous Studies (RJ),and Aquatic Habitat and Instream Flow Studies (AH).Reports prepared by the ADF&G prior to 1983 on this subject are available from the APA. The information in this report summarizes the findings of the 1983 open water field season investigations.Beginning with the 1983 reports,all reports were sequentially numbered as part of the Alaska Department of Fish and Game Susitna Hydro Aquatic Studies Report Series.

During the 1983 open water season (May-October,1983)baseline surface and intragravel water temperature data were recorded in the mainstem Susitna River and its peripheral side channel,side slough,upland slough and tributary habitats.Although data was collected from the estuary (RM 0.0)to above the Oshetna River (RM 235.7),the study concentrated on the reach of the river from the Parks Highway Bridge (RM 83.9)to the Oshetna River (RM 233.4).During the 1983 open water season surface water temperatures in the mainstem Susitna River generally increased downstream from RM 235.7 to RM 103.0.Surface water temperatures recorded at RM 83.9 were colder reflecting the influences of the Tal keetna and Chulitna Rivers.Intragravel temperatures were recorded at sites from RM 103.3 to RM 142.3.Warmest intragravel temperatures were recorded at the most upstream site.The influence of mainstem temperatures on surface water temperatures in side sloughs or side channels resulting from mainstem breaching discharges was observed in Side Channels 10,Upper 11,and 21,and in Side Sloughs 9 and 2l. Intragravel temperatures recorded in side channels and side sloughs were influenced by groundwater upwelling or mainstem temperatures. Variability in intragravel temperatures recorded within a side channel or side slough was observed in Upper Side Channel 11 and Slough 8A. Results of these investigations will be used to evaluate the influences that seasonal water temperatures have a fi sh and fi sh habitats and to calibrate or validate various temperature models. i .- TABLE OF CONTENTS ABSTRACT.•••. •••. ••••••. ••••. ••. •. •. . •••••. •••••. •. •. ••. . . •. . •. . •i TABLE OF CDNTEI~TS ••••••••••••••••••••••••••••••••lt...............ii LIST OF FIGURES..................................................ix LIST OF TABLES...................................................xix 1.0 INTRODUCTION................................................1 1.1 Background ••........••.••...••...••..•.......••.o......1 1.2 FY84 Objectives........................................1 1.2.1 Mainstem Habitats...............................1 1.2.2 Side Channel Habitats •••••••••••••.••..•••••••••1 1.2.3 Side and Upland Slough Habitats.................2 1.2.4 Tributary Habitats..............................2 2.0 METHODS.....................................................3 2.1 Site Selection..........................................3 ....2.1.1 Mainstem Habitats .3 2.1.2 Side Channel Habitats...........................3 2.1.3 Side and Upland Slough Habitats.................3 2.1.4 Tributary Habitats..............................3 2.2 Field Data Collection •.••••~...........................3 2.2.1 Peabody Ryan Temperature Recorders (Thermographs)...7 2.2.2 Omnidata Temperature Recorders (Datapods).......7 2.2.3 Advantages and Disadvantages of the Instrumentation.................................8 2.3.1 Peabody Ryan Te~perature Recorders (Thermographs)..................................8 !I 2.3 Analytical Approach .8 2.3.2 Omnidata Temperature Recorders (Datapods).......9 ii ---~--,~--_._~-_.,----- 16 3.0 RES ULTS •••••.•.••••••0 ••••••0 ••••••••••••Co •••••••ill •••••••ill • • • •10 3.1 Mainstem Habitats •••iIl ••co ••••••••••••••••••••••~•••••••••G 10 3.1.1 Lower Reach (Estuary,RM 0.0 to Parks Highway Bridge,RM 83.9)..........................10 3.1.1.1 Estuary (RM 4.5)to Mainstem above the Yentna (RM 29.5).........................10 3.1.1.2 Above the Deshka River (RM 41.1)to Parks Highway Bridge (RM 83.9)...........13 3.1.2 Middle Reach (Parks Highway Bridge,RM 83.9 to Devil Canyon,RM 150.0)........................13 3.1.2.1 Parks Highway Bridge (RM 83.9)to Talkeetna Fishwheel Camp (RM 103.0)......13 3.1.2.2 Talkeetna Fishwheel Camp (RM 103.0), Curry Fishwheel Camp (RM 120.7),Above Gold Creek (RM 136.8),and Devil Canyon (RM 150.0).......•.G •••••••••••••••••••• """" 3.1.2.3 Curry Fishwheel Camp (RM 120.7),at Gold Creek Bridge (RM 136.6)(site of old USGS recorder),Above Gold Creek (RM 136.8).•..•.•....•.•.••....... 3.1.2.4 Talkeetna Fishwheel Camp (RM 103.0), Curry Fishwheel Camp (RM 120.7), Below Gold Creek (RM 135.8),and Above Gold Creek (RM 136.8)••••.••••••••••••.• 3.1.2.5 LRX 9 (RM 103.2),LRX 29 (RM 126.1), LRX 57 (RM 142.3)•••.•••••.•.•••••.•.•.• 16 20 20 -

Specific locations of monitoring stations within each habitat were chosen primarily to provide water temperature data representative of the area.Surface and/or intragravel water temperatures were recorded during the FY 84 open water season.Surface water temperatures were collected at all sites and intragravel temperatures were collected at selected sites only. 2.1.1 Mainstem Habitats Temperature monitoring stations were established at 21 locations in the mainstem Susitna River from river mile 4.5 to river mile 235.7. 2.1.2 Side Channel Habitats Intragravel and surface water temperature monitoring stations were established at three side channel sites:Side Channel 10,Upper Side Channel 11,and Side Channel 21. 2.1.3 Side and Upland Slough Habitats Intragravel and surface water temperature monitoring stations were established in four side sloughs (8A,9,11,and 21)and two upland sloughs (10 and 19). 2.1.4 Tributary Habitats Surface water temperature monitoring stations were established in the Yentna River,Talkeetna River,Chulitna River,Gold Creek,Indian River, Portage Creek,Tsusena Creek,Deadman Creek,Watana Creek,Kosina Creek, Goose Creek,and the Oshetna River.An intragravel temperature monitoring station was establ ished in Fourth of July Creek to support the ADF&G SuHydro incubation study. 2.2 Field Data Collection Water temperatures were continuously recorded using either Peabody Ryan model J-90 submersible thermographs or Omnidata two channel datapod recorders.The Peabody Ryan temperature recorders were used at monitor- ing stations where surface water temperature alone was recorded.Two channel datapod recorders were installed at monitoring stations to simultaneously record intragravel and surface water temperatures.Two channel datapods were also used to monitor surface water temperature in association with stage or dissolved gas. 3 Table 3-1.Continuous temperature monitoring stations located in the Susitna River Basin during the 1983 open water season. - Temperatuf,-t Mainstem Susitna River River Mile Data Type Estuary 4.5 S ~ Flathorn Station 18.2 S Below Susitna Station 20.5 S -Susitna Station 25.8 S Above Yentna River 29.5 S Above Deshka River 41.1 S Parks Highway Bridge (Site 3)83.9 S Talkeetna Fishwheel Camp 103.0 S LRX 9 (Sites 1 and 2)103.2 S~I Curry Fishwheel Camp 120.7 S -LRX 29 (Site 1)126.1 S~I Below Gold Creek 135.8 S -Gold Creek Bridge (Site of old USGS recorder)136.6 S Above Gold Creek 136.8 S LRX 57 (Sites 1 and 2)142.3 S~I .....

I 2.2.1 Peabody Ryan Temperature Recorders (Thermographs) The Peabody Ryan model J-90 temperature recorders (thermographs)contin- uously record temperatures on a 90-day strip chart.Instrument accura- cy,as stated by the manufacturer,is ±O.6°C.Prior to field installa- tion,each instrument was screened at two temperatures (O°C and between 10-16°C)using a calibrated American Society for Testing and Manufactur- i ng (ASTM)thermometer as a standard.Thermographs found in error by more than 2°C at either screeni ng temperature were returned to the manufacturer for calibration.. Field installation procedures are outlined in the FY 84 ADF&G Su Hydro Aquatic Studies (May,1983 -June,1984)Procedures Manual (ADF&G 1983d).Temperatures were measured approximately two inches above the streambed. All thermographs were inspected twice each month to ensure accuracy and to detect malfunctioning instruments.Each time the thermographs were checked an instantaneous water temperature measurement was taken using a calibrated Brooklyn thermometer (accuracy ±O.l°C). 2.2.2 Omnidata Temperature Recorders (Datapods) Omnidata model DP2321 two channel temperature recorders (datapods) simultaneously record intragravel and surface water temperatures using TP10V temperature probes.Instrument accuracy,as stated by the man- ufacturer,Omnidata International,is ±O.l°C.Temperature data are recorded on an ultraviolet,erasable electronic memory chip referred to as a data storage modul e (DSM).Temperatures are measured every five minutes and the mean,minimum,and maximum temperature measured during each six-hour interval are recorded on the DSM.Prior to installation each temperature probe was cal ibrated by Dryden and LaRue Engineers and assigned a correction factor. Field installation procedures are outlined in the ADF&G Su Hydro Aquatic Studies (May,1983 -June,1984)Procedures Manual (ADF&G 1983d). Intragravel temperatures are measured at a depth of approximately 15 inches.Surface water temperatures are measured approximately two inches above the substrate. Datapods were examined twice each month to ensure accuracy and to detect mal functioning units.The temperature probes and cabl es were checked for physical damage,dewatering,or siltation.The operating condition of the datapod is checked by activating a short display sequence.The following information is displayed by the instrument,and recorded by the biologist:errors made in storage,number of storage points used, mi nutes unti 1 the next recordi ng,and current temperatures.An i nstan- taneous surface water temperature was also measured with a calibrated Brooklyn thermometer (accuracy ±O.l°C). A datapod model DP211SG two channel millivolt/temperature recorder was used to record temperature in association with stage or dissolved gas. Data are measured and stored every hour.Accuracy of the temperature sensor is ±O.5°C. 7 Field installation methods for the model DP211SG two channel datapods are outl ined in the FY 84 ADF&G Su Hydro Aquatic Studies (May,1983 - June,1984)Procedures Manual (ADF&G,1983d).These units were also examined twice each month using methods outlined for the model DP 2321 datapod. 2.2.3 Advantages and Disadvantages of the Instrumentation The datapod temperature recorder has several favorable features not offered by the Ryan temperature recorder.The datapod measures water temperatures more accurately (±O.l°C versus ±O.6°C).The datapod is capable of monitoring temperatures at two locations,or recording surface and intragravel temperatures simultaneously.Because the Ryan temperature recorder is an immersible unit,it is subject to potential loss or damage caused by high flow conditions or debris.The datapod recorder which houses the data storage module is installed on land and therefore is considered safe from water or debris damage.Only the datapod probes which are immersed in the water are subject to loss or damage.Because the data pod data is retrieved directly from the data storage module using a computer,data reduction is more accurate and efficient.The advantages of the Ryan thermographs include the relatively simple installation and monitoring procedures,and the avail- ability of a strip chart recording to evaluate the temperature record- ings.Disadvantages of the datapod temperature recorder include high instrument cost,and complex installation and monitoring procedures. Also because the datapod temperature record is retrieved as tables of mean,minimum,and maximum temperatures,occassionally it is difficult to detect erroneous data. 2.3 Analytical Approach 2.3.1 Peabody Ryan Temperature Recorders (Thermographs) Using field notes as a guide,all Ryan thermograph strip charts were screened for anomalous temperatures which may have resulted from instru- ment failure,dewatering,or siltation.From the strip charts,a reduced temperature data base is obtained as two hour point tempera- tures. A correction value for each strip chart was determined as the difference between the temperature obtained with a calibrated Brooklyn thermometer (accuracy ±O.l°C)and the thermograph reading at the time the strip chart was removed.(A correction value is determined at the time of strip chart removal rather than installation because response time of the recorder to actual water temperatures can vary with each installa- tion.)The correction value was then used to correct the two-hour point temperature data obtained from each strip chart.From these corrected data bases,daily,USGS water year weekly,and monthly minimum,mean, and maximum surface water temperatures were computer calculated. 8 ,- 2.3.2 Omnidata Temperature Recorders (Datapods) Water temperature data were retrieved from the datapod temperature recorders as six-hour minimum,mean,and maximum temperatures by reading the data storage module (DSM)via an Omnidata model 217 Datapod/cassette reader into a microcomputer.These six-hour data bases were edited and corrected for storage errors and anomalous data which may have resulted from dewatering,siltation or instrument failure.From these corrected data bases,daily,USGS water year weekly,and monthly mean,minimum, and maximum temperatures were computer calculated. 9 3.0 RESULTS Results of the 1983 open water field season continuous water temperature monitoring program are presented according to the following habitat types:mainstem,side channel,slough (side and upland)and tributary. 3.1 Mainstem Habitats Results of the 1983 open water season continuous temperature monitoring program conducted in the mainstem Susitna River are presented below according to reach of river:Lower Reach (Estuary,RM 4.5 to Parks Highway Bridge,RM 83.9),Middle Reach (Parks Highway Bridge,RM 83.9 to Devil Canyon RM 150.0),and Upper Reach (Devil Canyon,RM 83.9 to above the Oshetna River,RM 235.7).Within each reach of river,data which were recorded at temperature stations to comply with similar objectives are compared and presented together. - 3.1.1 Lower Reach (Estuary,RM 4.5 to Parks Highway Bridge,RM 83.9) Continuous surface water temperature data were collected at seven monitoring stations in the lower Susitna River from the Estuary tempera- ture station located at river mile 4.5 to the Parks Highway Bridge located at river mile 83.9.Site maps for each of these temperature stations are presented in Appendix Figures 3-A-1 to 3-A-4 and 3-A-6 to 3-A-8.Daily and monthly minimum,mean,and maximum surface water temperatures for each station are presented in Appendix Tables 3-A-2 to 3-A-8.Water year weekly temperatures are presented in Appendix Tables 3-A-54 to 3-A-60.The entire period of record,1981-1983,for each monitoring station is presented in Appendix Table 3-A-1. 3.1.1.1 Estuart (RM 4.5)to Mainstem above the Yentna River _RM 29.5) The temperature monitoring stations located in the Mainstem Susitna River from the Estuary upstream to above the Yentna River were established to collect baseline surface water temperature data and to support the evaluation of eulachon spawning habitat (Chapter 5 of this report).Temperature stations established at the Estuary (RM 4.5), Flathorn Station (RM 18.2),below Susitna Station (RM 20.5),Susitna Station (RM 25.8),and above the Yentna River (RM 29.5)were monitored only from mid-May to mid-June or mid-July.To compare temperatures recorded at these stations,a plot of the mean daily surface water temperatures was developed (Figure 3-2).Ranges,25th,50th (median), and 75th percentiles of surface water temperatures collected at these stations are shown in Figure 3-3. Surface water temperatures recorded at these monitoring stations ranged from 4.3 0 (recorded at the Estuary in May)to 14.7 0 (recorded at Flathorn Station in June).Because periods of records vary,it is difficult to observe trends in temperature data collected at monitoring stations from May to mid-June.The temperature stations located at the 10 }-~-__I ;1 -1 -1 ).J )J ~ 16 15 14 13 12 u ~IIwa:: 10::J ~ <:( cr 9 W Go :::f 8w ~ 7 0::.....W.....~6 <:( 3; 5 4 3 2 o I'1'-'"',\I \,: .\r...,..,..,"I ......., , ,I"t , :....'.......,.,'"t 'Ir:...:~\;\"\}, ::..

Estuary,below Susitna Station,and above the Yentna River were removed in mid-June leaving only Flathorn Station and Susitna Station.Surface water temperatures were monitored at these sites through July.During this period,daily mean temperatures were consistently warmer at Flathorn Station. 3.1.1.2 Above the Deshka River (RM 41.1)to Parks Highway Bridge (RM 83.9) Surface water monitoring stations were established above the Deshka River (RM 41.1)and at the Parks Highway Bridge (RM 83.9)to collect baseline mainstem Susitna River temperature data and to determine if the Delta Islands affect mainstem surface water temperatures.Ranges,25th, 50th (median),and 75th percentiles of surface water temperatures collected at these stations are presented in Figure 3-3.A Plot of mean daily surface water temperatures is presented in Figure 3-4. Although surface water temperatures recorded at the two stations dif- fered,it is difficult to relate this directly to the influence of the Delta Islands.Mean daily surface water temperatures were higher at the monitoring station located above the Deshka River than at the Parks Highway Bridge from mid-June until mid-September when the trend re- versed.Slightly warmer surface water temperatures were recorded at the Parks Highway Bridge monitoring station through mid-October.A gap in the data recorded at the Parks Highway Bridge from August 22 to Septem- ber 10 resulted from instrument failure. 3.1.2 Middle Reach (Parks Highway Bridge,RM 83.9 to Devil Canyon,RM 150.0) Continuous surface and/or intragravel water temperature data were obtained at ten monitoring stations in the middle reach of the Susitna River from the Parks Highway Bridge located at river mile 83.9 to Devil Canyon located at river mile 150.0.Site maps of these temperature stati ons are presented in Appendix Fi gures 3-A-8,3-A-11 to 3-A-13, 3-A-17, 3-A-18,3-A-21,and 3-A-23.Daily and monthly minimum,mean, and maximum surface water temperature for each station are presented in Appendix Tables 3-A-8 to 3-A-19.Water year weekly temperatures are presented in Appendix Tables 3-A-60 to 3-A-71.The periods of record for these monitoring stations,1981-1983,are presented in Appendix Table 3-A-1. 3.1.2.1 wheel Cam to Ta 1keetna Fi sh- To determine the influence of the Chulitna River and the Talkeetna River on mainstem Susitna River temperatures,surface water temperature data collected at the monitoring station at Parks Highway Bridge (RIIil 83.9) was compared to temperature data collected at the monitoring station at the Talkeetna Fishwheel Camp (RM 103.0).The monitoring station at Parks Highway Bridge is located downstream of the tributaries while the monitoring station at Talkeetna Fishwheel Camp is located upstream of the tributaries.A plot of the mean daily surface water temperatures recorded at the two temperature stations is presented in Figure 3-5. 13 I.

Surface and intragravel water temperatures at LRX 29 were similar from mid-May until late September.In late September mean surface water temperature cooled to a minimum of -O.l°C while the minimum intragravel temperature was 1.0°C.In early October intragravel and surface water temperatures increased to 3.9°C and 3.4°C,respectively,and then declined.Throughout October intragravel temperatures were warmer than surface water temperatures. 3.1.2.5.6 Intragravel versus surface water tempera- ture at LRX 57 (RM 142.3) A plot of intragravel and surface water temperature recorded at LRX 57 (RM 142.3)is presented in Figure 3-16. Because of a malfunctioning probe,surface water temperatures were not recorded at LRX 57 until August 4.Between August 4 and September 11 intragravel temperatures were generally higher than the surface water temperatures.The probes were relocated to Site 2 on September 11 to prevent dewatering.In September and October mean daily intragravel temperatures remained warmer than surface water temperatures.In late September minimum surface water temperature was -O.l°C,while the minimum intragravel temperature was 2.1°C.Mean monthly water temperatures calculated for October were 3.0°C (intragravel)and O.5°C (surface). 3.1.2.6 LRX 9 (RM 103.2)and Talkeetna Fishwheel Camp (RM 103.0) Because the temperature monitoring stations at Talkeetna Fishwheel Camp (RM 103.0)and LRX 9 (RM 103.2)were in close proximity,a comparison between surface water temperatures recorded at the si tes was made.A plot of mean daily surface water temperatures recorded at LRX 9 and Talkeetna Fishwheel Camp is presented in Figure 3-17. Surface water temperatures measured at the monitoring station at LRX 9 correspond closely to surface water temperatures recorded at Talkeetna Fishwheel Camp.The greatest difference in mean daily surface water temperature occurred on September 17 when the temperature at the moni- toring station at LRX 9 was 100°C higher than the temperature at the monitoring station at Talkeetna Fishwheel Camp. 3.1.3 Oshetna RM 150.0 to above the Continuous surface water temperature data were recorded at three mainstem locations in the upper reach of the Susitna River from Devil Canyon (RM 150.0)to above the Oshetna River (RM 235.7).Mainstem temperature monitoring stations were establ ished at Devil Canyon {RM 28 ]1 1 i 1 I 1 I 1 23 22 21 20 19 18 17 0 16 !....ISWa::14::> ti 13 a::w 12 Q. ~II N w 1.0 t-10 0::9W ~8 3:7 6 S 4 3 2 I 0 tf ;\\/\._\ • \-.A...!'.tJ\'\f'..J \1\'\.J\.I \,./''V V 'v ,-,.V .'-0..'--- ("v.; / ./ _._MEAN DAllY DISCHARGE.SUSITNA R.

Figure 3-21 indicates that intragravel temperatures exhibit less varia- tion than surface water temperatures.Surface water temperatures recorded between July 17 and October 31 ranged from 0.2°C to 18.6°C. Intragravel temperatures vari ed between 3.0°C and 5.8°C.In general intragravel temperatures were cooler than surface water temperatures from mid-July through late September.At this time surface water temperatures decreased greatly while intragravel temperatures declined slightly. 3.2.2 Upper Side Channel 11 -Sites 1 and 2 (RM 136.3) The temperature recorder at the monitoring station in Side Channel 21 - Site 1 was installed on July 28 to record surface and intragravel water temperatures (Figures 3-22 and 3-23).The temperature recorder was relocated to Site 2 on September 12 to monitor an egg development site for the ADF&G egg incubation study.Surface water temperatures recorded at Site 1 ranged from 3.3°C to 15.3°C and intragravel water temperatures varied between 5.2°C and 6.5°C. When the recorder was moved to Site 2 on September 12,the mean daily intragravel temperature decreased from 5.3°C to 4.8°C while the mean daily surface water temperature increased from 5.6°C to 6.1°C.At Site 2,surface water continued to be warmer than intragravel temperatures until late September when the trend was reversed.Intragravel tempera- tures remained warmer than surface water temperatures through October. Surface water temperatures recorded at Site 2 (September 12 to October 31)ranged from 0.6°C to 9.5°C,and intragravel temperatures ranged from 2.6°C to 5.5°C. 3.2.3 Side Channel 21 -Sites 1 and 2 (RM 141.0) The temperature monitoring station located at Side Channel 21 -Site 1 was installed on August 29 to record surface and intragravel water temperatures.The recorder was relocated to Site 2 on September 13 to monitor an egg development site for the ADF&G incubation study.The limited data available from Site 1 show that surface water temperatures were warmer than intragravel water temperatures (Figures 3-22 and 3-24). Surface water temperatures ranged from 4.7°C to 9.2°C and intragravel temperatures varied between 3.9°C and 7.9°C. After installation at Site 2,mean intragravel water temperatures increased from 4.9°C (Site 1)to 6.2°C (Site 2).Because the surface water probe was dewatered prior to installation at Site 2 (data gap)no immedi ate compari sons can be made between surface water temperatures recorded at Sites 1 and 2.Mean intragravel water temperatures were warmer than the surface water from September 13 to October 1.However, during thi s time peri od,surface water temperatures exhibited dai ly fluctuations of up to 3.8°C per day while intragravel daily fluctuations were usually less than O.5°C.In October mean dai ly surface water 36 - 16 15 14 13 12 ~ u II!...

The periods of record for the monitoring stations,1981-1983,are pre- sented in Appendix Table 3-A-l. 3.3.1 Side Slough 8A (RM 125.6) Temperature monitoring stations in Side Slough 8A were located at Lower Side Slough 8A (RM 125.6)and Upper Side Slough 8A (RM 126.6).See Appendix Figure 3-A-13 for site locations. 3.3.1.1 Lower Side Slough 8A -Sites 2 and 3 (RM 125.6) Surface and intragravel water temperatures were recorded at Lower Side Slough 8A (Site 2)from May 1 to August 24.Surface water temperatures were consistently warmer than intragravel water temperatures (Figures 3-25 and 3-26).Surface water temperatures ranged from 1.3°C to 17.4°C and intragravel water temperatures varied between 3.1°C and 5.5°C.The gap in the surface water temperature data from June 2 to July 5 was due to siltation of the temperature probe.This problem was not apparent when the temperature recorder was serviced in June because of high water conditions. On August 25 the recorder was reinstalled at Site 3 because it was felt that the new site would be more appropriate for winter data collection. Between August 25 and mid-September surface water and intragravel water temperatures were dissimilar.During this time period~mean daily temperatures recorded were sometimes 4°warmer than intragravel tempera- tures. From mid-September through October surface and intragravel water temper- atures decreased and the temperatures recorded were similar.The mean monthly surface water temperature in September was 6.0°C while the mean monthly intragravel temperature was 5.5°C.The mean monthly surface and intragravel temperatures recorded in October were 1.8°C and 1.7°C, respectively. 3.3.1.2 Upper Side Slough 8A (RM 126.6) Surface water temperatures recorded at the monitoring station at Upper Side Slough 8A (RM 126.6)were warmer than intragravel temperatures from May to late August (Figures 3-26 and 3-27).Between May 1 and August 25 surface water temperatures varied from 1.3°C to 11.3°C~while intra- 41 MEAN DAILY SURFACE WATER TEMPERATURE ------LOWER SLOUGH 8A-SITE2(RM !25.6) ······---·LOWER SLOUGH 8A-SITE 3 (RM 125.61 MEAN DAILY INTRAGRAVEL WATER TEMPERATURE -LOWER SLOUGH 8A·SITE 2 (RM 125.81 _••-LOWER SLOUGH 8A -SITE 3 (RM 125.61".I'I, 'I ", , I , " I \ , I ~ "I I I ,',t , I I "lUI\I 'i'I I I" " , , ' I I :\1 ,}~ I I , I I I I I ," I I ,'\ I I " I",1 '"",~f , ".", I ,"',.,~'~V'.i \'~:\,~ .'.1 1;:.:\,j \!t \11\\J V. -v../I n V\\'.:,\v:~'\~:........:'~~:~.~~~ o 16 15 14 13 12 ~ u ~II w a::: =>10 I- <ta:::9wa.

Throughout the remainder of the open water season temperatures recorded at Sites 3 and 4 were similar. Figure 3-40 illustrates the daily fluctuation which occurred at Sites 2 and 3.In June temperatures often fluctuated 2.5°per day.Tempera- tures recorded at Site 2 (May 29 to June 14)ranged from 6.7°e to 9.2°C. Temperatures at Site 3 ranged from D.Ooe (in September)to 10.0°C (in July),while temperatures at Site 4 ranged from O.O°C (in September)to 9.5°C (in July). 3.4.2.3 Fourth of July Creek (RM 131.1,TRM 0.0) In support of the ADF&G egg incubation study,intragravel temperature monitoring stations were installed in Fourth of July Creek and down- stream of the tributary mouth within the clearwater plume on September 1.Generally,temperatures recorded in the Creek and in the plume were similar.However,the plume temperatures appear to lag behind the Creek temperatures (Figure 3-41).For example,when temperatures decreased rapidly in late September,the minimum creek temperature was recorded on September 25,while the minimum plume temperature was recorded on September 29.Intragravel temperatures recorded in the Creek from September 1 to October 31 varied from -0.3°C to 8.9°C.Intragravel temperatures recorded in the cl earwater pl ume ranged from -0.2°C to 7.9°C. 58 - - - ~-~1 J J J J 16 15 14 13 12 ~u 0 II w a: ::l 10 ~a:9 wa.

Temperature differences between the Yentna River and the mainstem Susitna River at Susitna Station were not as great.The average July mainstem temperature at Susitna Station was 11.3°.Because temperature data were not recorded at Susitna Station after July,further comparisons between mainstem Susitna River temperatures at Susitna Station and temperatures in the Yentna River were not made. In August surface water temperatures recorded at the Yentna River were also lower than temperatures recorded in the mainstem above the Deshka River.Average August temperatures were 9.0°C in the Yentna River and 10.7°in the the mainstem Susitna River above the Deshka.In September and October,temperatures recorded in the Yentna River were similar to mainstem temperatures recorded above the Deshka River. 3.5.1.2 A comparison of the surface water temperatures in the Chulitna and Talkeetna Rivers to main- stem Susitna River surface water temperatures A plot of mean daily surface water temperatures recorded at the Susitna River monitoring stations at the Parks Highway Bridge (RM 83.9)and Talkeetna Fishwheel Camp (RM 103.0),and those recorded in the Chulitna River (RM 98.6 TRM 0.6,2.4,4.4)and the Talkeetna River (RM 97.2,TRM 1.5)is presented in Figure 3-54.From mid-June to September tempera- tures in the Chulitna River were colder than those recorded in the Talkeetna and Susitna Rivers.During this time the warmest temperatures were recorded in the mainstem monitoring station located upstream of the tributaries at Talkeetna Fishwheel Camp.For example,during August the mean monthly surface water temperatures were 6!9°in the Chulitna River and 9.4 0 in the Talkeetna River.The mean monthly surface water temper- atures in the mainstem were 10.4°at Talkeetna Fishwheel Camp and 10.2° at the Parks Highway Bridge (located downstream of the tributaries). Temperatures recorded at the Parks Highway station and the Talkeetna River were similar in mid-September.By late September similar temperatures were recorded at all of the stations. 3.5.1.3 Comparison of intragravel water temperatures recorded at Fourth of July Creek and in the _ clearwater plume of Fourth of JUlf Creek to the mainstem Susitna River intragrave temperatures Intragravel water temperatures were recorded in Fourth of July Creek (RM 131.1,TRM 0.1)and the clearwater plume of Fourth of July Creek from September 1 to October 31.These water temperatures were compared to the mainstem intragravel water temperatures obtained at LRX 29 (RM 76 l t 1 1 !J e 16 15 14 13 12 0 .~IIw 0:: 10::l I- <t 0::9 W Q..::!:8w I-....,.7....,.a:w I-6 <t ~5 4 3 2 o MEAN DAll'!'SURFACE WATER TEMPERATURE ~-'l'ENTNAR.-SITE 2 (TRM4.0,RM 28.0) -----MSA80VE DESHKA R.(RIlI4U) _.•-MS AT SUSITNA STATION (Rill 2!l.11 , i I~I I ,I I I I I I I I ~ i i i i I I 15 I III I'III I III I 15 I 15 I MAY JUN E JULY AUG SEPT OCT NOV 1983 Figure 3-53 Mean daily surface water temperatures collected during the 1983 open water season at the Yentna River -Site 2 (RM 28.0,TRM 4.0), Mainstem Susitna River above the Deshka River (RM 41.1),and Main- stem Susitna River at Susitna Station'(RM 25.8). 16 15 14 13 12 ~ 0 II~ W t:r 10::> I-«9t:r W 0..S::::i: W I-1 t:r W 6I-'"-..l «CO 3:5 4 3 2 o MEAN DAILY SURFACE WATER TEMPERATURE ---MS PARKS HWY BRIDGE-SITE 5 (RM 115.9) -----MS TALKEETNA CAMP (RM 105.0) ----TALKEETNA R.-SITE 2 (TRM U,RM 97.2) ---------CHULITNA R.-SITE Z (TRM 0.6,RM 98.6) ---CHULITNA R.-SITE 5 (TRM 2.4,RM 98.6) _.-CHULITNA R.-SITE 4 (TRM 4.4,RM 98.6) I MA'i 15 I "UN E 15 I JULY 15 I AUG 1983 15 I SEPT 15 I OCT 15 I NOV Figure 3-54.Mean daily surface water temperatures collected during the 1983 open water season at Mainstem Susitna River at Parks Highway Bridge -Site 3 (RM 83.9), Mainstem Susitna River at Talkeetna Fishwheel Camp (RM 103.0),Talkeetna River -Site 2 (RM 97.2.TRM 1.5),and the Chulitna River -Site 2 (RM 98.6, TRM 0.6),Site 3 (RM 98.6,TRM 2.4),Site 4 (RM 98.6,TRM 4.4).

Figure 3-55 indicates that the temperature trends recorded at all three locations appear to be similar.However,the temperatures obtained in the plume seems to lag behind the temperatures recorded in the creek and in the mainstem.For example,in late September when temperatures declined,m"inimum temperatures were first recorded in the creek on September 25 and in the plume on September 29.At this time the minimum temperatures were recorded in the mainstem at LRX 29 on September 26. Minimum temperatures recorded in the creek were lower than those recorded in the plume or the mainstem.The minimum September temperatures were 0.8°C in the plume,-0.3°C in the creek and 1.0°C in the mainstem.Further comparisons among these three sites are difficult because of the variability occurring in the plume of Fourth of July Creek which is dependent upon flow from the creek,the availability of surface water in the side channel where the plume is located,and the limited data including the absence of surface water temperature data from Fourth of July Creek • 3.5.1.4 A comparison of surface water temperatures in Gold Creek to Mainstem Susitna River surface water temperatures. The surface water temperatures recorded in the Gold Creek tributary (RM 136.7,TRM 0.2)were compared to those recorded in the mainstem Susitna River.Figure 3-56 is a plot of mean daily surface water temperatures recorded in the Gold Creek tributary and in the mainstem Susitna River above Gold Creek (RM 138.6),at Gold Creek Bridge (RM 136.6)(in the Gold Creek thermal plume),and at Curry Fishwheel Camp (RM 120.7).A review of this plot shows that from mid-May to early October the Gold Creek tributary is consistently cooler than the mainstem Susitna River. The mainstem station downstream of the tributary in the thermal plume, was also cooler than the remaining Susitna River sites.Warmest temperatures were recorded at the Station at Curry Fishwheel Camp.No relationship between discharge and temperature can be defined. 3.5.1.5 A comparison of Indian River Surface water temperatures to surface surface water tempera- tures in the mainstem Susitna River A comparison of surface water temperatures in Indian River (RM 138.6, TRM 1.0)to mainstem Susitna River surface water temperatures recorded at Devil Canyon (RM 150.0)and above Gold Creek (RM 136.8)is presented in Figure 3-57.Between May and July temperatures recorded at the monitoring station at Indian River (RM 138.6,TRM 1.0)were generally lower than mainstem temperatures recorded at Devil Canyon (RM 150.0)and above Gold Creek (RM 136.8)(Figure 3-56).Mean June temperature in 79 16 15 14 13 12 0 !L-II w 0:: ::l 10 l- e:( 0::9w G- OO ::i:8 a w I- 0:: 7 w I-6 e:( ?:5 4 3 2 o MEAN DAilY INTRAGRAVEl WATER TEMPERATURE ---4th OF ~UlY PLUME IRM 131.I) -----4th OF JULY CR.IRM 131.1) ----MS AT lRX 29 I RM 126.1) t\(\f\.f1r1/'v r \fl1 \" I \I .~!v \t.

""" 3.5.2.2 A comparison of surface and intragravel water water temperatures record- ed in Upper Side Channel 11 to mainstem surface water temperatures recorded upstream at the station above Gold Creek is presented in Figure 3-60.Surface water temperatures occurring in this side channel were similar to the mainstem Susitna River temperatures from mid-July to September.It has been determined that this side channel is breached at mainstem discharges of as low as 12,700 cfs (Chapter 1).During mid- July to September,the side channel was breached continuously. In September,the temperature station in Upper Side Channel 11 was moved to a new location -Site 2.At this site surface temperatures in the side channel continued to be s"imilar to mainstem temperatures until late September.During this time,however,the mean daily surface water temperature in the mainstem decl ined to O.l°C,wh"ile the lowest mean daily side channel temperature was 2.0°C. Intragravel water temperatures in the"side channel were cooler than surface temperatures and showed little variation from late-July to September.When the temperature probes in Side Channel 11 were reinstalled at Site 2,the intragravel temperatures corresponded closely to side channel andmainstem surface temperatures.Mainstem data were not recorded in October. ~. 3.5.2.3 A plot of surface and intragravel water temperatures recorded in Side Channel 21 and mainstem surface and intragravel water temperatures recorded at LRX 57 is presented in Fi gure 3-61.In 1ate august and early September,surface and intragravel temperatures recorded at Side Channel 21 -Site 1 correspond closely to intragravel and surface water temperatures recorded at LRX 57.Generally,mainstem surface water temperatures were warmest and side channel intragravel temperatures were coolest.

Therefore,surface water temperature data were not collected continuously during the 1983 open water season at many of the monitoring stations.The limited data available from May to mid-June indicate that during this time downstream surface water temperature trends are not apparent.This may be due in part to the variable periods of record or because the temperature stations were establ ished at eulachon study areas which may not have been representative temperature sites. From mi d-June through Ju ly surface water temperature data was recorded at four monitoring stations located at Flathorn station (RM 18.2), Susitna Station (RM 25.8),above the Deshka River (RM 41.1)and at the Parks Highway Bridge (RM 83.9).During this time temperatures generally increased downstream.Only the data recorded at Susitna Station does not fit this temperature trend.The temperatures recorded at Susitna Station (RM 25.8)are cooler than those recorded above the Deshka River (RM 41.1).This is likely due to cooling caused by the influence of Yentna River which provides a substantial discharge to the Susitna River. Temperatures were recorded at mainstem monitoring stations located above the Deshka River (RM 41.1)and at the Parks Highway Bridge from mid-June through October.From mi d-June through August,surface water temperatures recorded above the Deshka River were warmer than those recorded at the Parks Highway Bridge.This increase in temperature is probably due to the influence of Delta Island complex which extends from river mile 43 to river mile 51.The complex divides the Susitna River into two main channels and a series of small islands and channels. "'" In September and October,surface water temperatures recorded at the two locations were similar.This is probably due to the decreased influence of air temperatures and solar radiation on surface water flowing through the Delta Islands.""" 4.1.2 to Surface Water Temperature Surface water temperatures recorded in the Susitna River generally increased downstream from Devil Canyon (RM 150.0)to the Talkeetna Fishwheel Camp (RM 103.0).Surface water temperatures recorded at the Parks Bridge (RM 83.9)were colder,reflecting the influence of the Talkeetna and Chulitna Rivers. 102 - Mean monthly temperatures for June and August recorded at the station above Gold Creek are lower than upstream temperatures. be due in pa rt to the i nfl uence of the I nd i an River therma 1 mainstem temperatures at this location.

Surface water temperatures were association with dissolved gas. thi s site may be attributed to temperature probe. The surface water temperatures recorded in the mainstem Susitna River at Gold Creek Bridge (RM 136.6)were colder because the probe was located in the Gold Creek thermal plume.The data were collected in this location to aid in the evaluation of previous temperature data collected by the USGS at the Gold Creek Station (USGS 15292000),which had also been located in the Gold Creek thermal plume. Intragravel Water Temperatures Intragravel temperatures recorded at LRX 9 (RM 103.3),LRX 29 (RM 126.1) and LRX 57 (RM 142.3)all exhibit similar temperature patterns;however, actual temperatures varied among the three stations.The warmest intragravel water temperatures were recorded at the most upstream site, LRX 57,and the coolest were recorded at the most downstream site,LRX 9. Only at LRX 29 did intragravel temperatures correspond closely to surface water temperatures.Intragravel and surface temperatures at LRX 9 were similar;however,intragravel temperatures were lower indicating the influence of the substrate on intragravel temperatures.At LRX 57 intragravel water temperatures were consistently warmer then surface water temperatures indicating that either the intragravel mainstem water source differs from that of the surface water or the substrate conditions are influencing the intragravel temperatures.This phenomenon was noted in September,1983.At this time both the temperature probes and the recording instrument were evaluated and found to be operaing correctly.The increase in intragravel temperatures at LRX 57 in October may,however,be due to drift in a temperature probe. 4.1.3 U er Reach -Dev il Can on (RM 150.0)to Above the shetna River RM 234.9 Surface water temperatures were monitored at two locations upstream of Devil Canyon during the 1983 open water season.Above the Oshetna River (Site 1,RM 234.9;Site 2,RM 235.7)and above Tsusena Creek (RM 181.9). Generally,surface water temperatures were warmer at the downstream site located above Tsusena Creek.The increased temperatures are primarily the result of the influence of several small tributaries.Temperatures recorded at Devil Canyon (RM 150.0)were similar to those recorded above Tsusena Creek throughout the 1983 open water season. 103 4.2 Side Channel and Side Slough Habitats Surface and intragravel water temperatures were obtained at side channel and side slough habitats located in the reach of Susitna river from Talkeetna to Devil Canyon.A major characteristic of these two habitat types is that at various mainstem discharges,mainstem water breaches or enters these habitats at their head portions.When these habitats are not breached by mainstem discharges the flow is primarily generated by surface water runoff and groundwater flow.Temperatures are influenced by solar radiation and groundwater.When breaching provides a sufficient volume of mainstem water to the slough or side channel, temperatures parallel the mainstem temperature.Side channel habitats are overtopped more often than side sloughs.Therefore,temperatures in side channels are more often similar to mainstem temperatures. Surface water temperatures recorded in Side Channel 10 (RM 134.0) correspond closely to mainstem temperatures when the side channel is breached by mainstem flows of 19,000 cfs or greater (see Chapter 1). Intragravel temperatures recorded in Side Channel 10 do not correspond to surface water temperatures indicating that the intragravel temperatures were probably located in an area of groundwater upwelling. Upper Side Channel 11 is breached by mainstem discharges as low as 12,700 cfs.During mid-July to September this side channel was continuously breached,and mainstem and side channel temperatures corresponded closely.In late September and October more variability between mainstem and side channel temperatures is evident.This is primarily attributed to the reduced frequency of mainstem breaching discharges. Intragravel water temperatures recorded at Upper Side Channel 11 from July to early September were not similar to surface water temperatures indicating the influence of groundwater.In early September the temperature probes were relocated to Site 3.The intragravel tempe"ratures then corresponded to surface temperatures showing the variability in intragravel temperatures within a side channel. The effects of mainstem temperatures on temperatures recorded in Side Channel 21 is evident through September. Surface water temperatures recorded in Lower Side Slough 8A reflect mainstem surface water temperatures because the location of the temperature monitoring station was influenced by mainstem backwater effects.The intragravel temperature monitoring station in Lower Slough 8A was not influenced by mainstem or slough surface water temperatures. The intragravel temperatures are lik~ly the result of groundwater upwell ing.When the intragravel station was relocated to a new site, the effects of mainstem temperatures on the intragravel temperatures in the slough are apparent,Again the variation in temperatures occurring within a slough is seen. A mainstem discharge of greater than 33,000 cfs is estimated to breach the upper portion of Si de Slough 8A and i nfl uence the temperatures recorded at the monitoring station located in Upper Side Slough 8A. 104 - - ·Surface water temperatures recorded in Side Slough 9 correspond closely to mainstem temperatures from mid-May through August.A mainstem discharge necessary to breach the slough (19,000 cfs)occurred frequently throughout this period.More variation in slough and mainstem temperatures occurred in September and October when discharges decreased.Intragravel temperatures recorded in Slough 9 exhibited 1ittle variation throughout the open water season.The intragravel temperature probe was apparently located in an area of groundwater upwell ing. Surface and intragravel water temperatures recorded in Slough 11 differed from mainstem temperatures.Slough 11 was never breached during the 1983 open water season. Surface water temperatures recorded at Lower Side Slough 21 reflected the influence of mainstem temperatures directly when Channel A6 Upper breached.Intragravel temperatures recorded in Lower Si de Slough 21 were not directly influenced by mainstem temperatures or discharges. Surface and intragravel temperatures recorded at Upper Slough 21 were influenced by mainstem temperatures when Slough 21 NW Head breached.In early May a breaching event caused by breakup of the mainstem dramatically reduced surface and intragravel temperatures in Upper Side Slough 21. 4.3 Upland Slough Habitat Upland Slough 19 maintained a narrow range of temperatures during the 1983 open water season indicating the lack of mainstem influences. 4.4 Tributary Habitats Surface water temperatures recorded in the mainstem Susitna River directly reflect the influence of the lower surface water temperatures contributed by the Yentna River,Ta"lkeetna River,and the Chulitna River.Although the temperature influence is less evident,tributaries contributing smaller volumes of water also affect mainstem surface water temperatures.Usually the clearwater plume of a smaller tributary is a good indicator of the effect of the tributary on mainstem water temperatures.The extent of the thermal plume depends upon tributary and mainstem discharge. Although tributaries such as Portage Creek,the Chulitna River, Ta"lkeetna River,and Indian River decreased mainstem temperatures during the warmer periods of the year,these tributaries can increase the mainstem temperatures during September or October. The temperatures in the small tributaries located above Devil Canyon are largely affected by air temperature and solar radiation.The combined influence of these warmer tributaries contributes to the increase in downstream Susitna River temperatures occurring from above the Oshetna River to Devil Canyon. 105 The late fall intragravel temperatures recorded at Fourth of July Creek were as low as -O.3°C.These temperatures were probably the result of anchor ice which was observed on the stream bottom.Data is not available to explain the lag time which was observed between irttragravel temperatures measured in Fourth of July Creek and those recorded in the plume. The low temperatures recorded in Gold Creek (-O.SOC)were probably due to the accuracy of the temperature probe which is ±O.SoC. 106 - - 5.0 GLOSSARY Backwater Area - A reach of stream with reduced or no velocity and a rise in stage resulting from a hydraulic or physical barrier. Backwater areas in habitats adjacent to the Susitna River usually are due to an increase in mainstem discharge and occur at the mouth of or within a side channel or slough. Breaching -The overtopping of the head of a side channel or side slo~gh by the mainstem river. Clearwater Plume -the extension of the clearwater of a tributary into the turbid mainstem at and below the confluenceof the two.Due to the different densities of the mainstem and tributary waters,these two water bodies do not readily mix,causing a clearly defined clearwater extension of the tributary along the river bank at end below the actual confluence.Size of the plume is a function of tributary flow and mainstem discharge. Datapod - A dual channel,electronic instrument capable of simul- taneously measuring and recording from each channel on a continuous basis.Datapods have been used to monitor stage,temperature and dissolved gas concentrations. Discharge -Discharge,or streamflow,is defined as the volume rate of flow of water passing a specific location for a specific point in time.Dimensions are usually expressed as cubi c feet per second (cfs).For the purpose of this report discharge will refer specif- ically to mainstem habitat and streamflow for side channel,slough and tributary habitats. DSM - A non-volatile,ultraviolet (UV)erasable,solid state data storage module capable of storing approximately 3 months of stage, temperature or dissolved gas concentration data. Gaging Station - A location which has been established for monitoring stage,flow and/or discharge. Habitat -The surrounding environmental conditions to which a particular species and life stage of fish responds both behaviorally and physiologically. Head -The upstream or point of origin of a lotic water body. Lower Reach (of the Susitna River)-The segment of the Susitna River between Cook Inlet and the Chulitna River confluence.(See also middle reach and upper reach). Mainstem Habitat -Consists of those portions of the Susitna River that normally convey water throughout the year.Both single and multi- ple channel reaches are included in this habitat category.Ground- water and tributary inflow appear to be inconsequential contribu- tors to the overall characteristics of mainstem habitat.Mainstem habitat is typically characterized by high water velocities and well armored streambeds.Substrates generally consist of boulder 107 and cobble size materials with interstitial spaces filled with a grout-like mixture of small gravels and glacial sands.Suspended sediment concentrations and turbidity are high during summer due to ~ the influence of glacial melt-water.Discharges recede in early fall and the mainstem clears appreciably jn October.An ice cover forms on the river in late November or December. Mean Daily Discharge -The computed mean mainstem discharge per 24 hour period for a USGS gaging station. Middle Reach (of the Susitna River)-The segment of the SusitnaRiver between the Chulitna River confluence and Devil Canyon.(See also lower reach and upper reach). Monitoring Station - A station set up for the collection of a particular data base. Mouth -The downstream confluence of a lotic water body with another water body. Overtopping -See breaching. Peripheral Habitats -Aquatic habitats adjacent to the mainstem Susitna River habitat (e.g.side channel,side slough,upland slough, tributary mouth and/or tributary habitats). Side Channel Habitat -Consists of those portions of the Susitna River that normally convey water during the open water season but become appreciably dewatered during periods of low mainstem discharge. Side channel habitat may exist either in well defined overflow channels,or in poorly defined water courses flowing through partially submerged gravel bars and islands along the margins of the mainstem river.Side channel streambed elevations are typical- ly lower than the mean monthly water surface elevations of the mainstem Susitna River observed during June,July,and August. Side channel habitats are characterized by shallower depths,lower velocities and smaller streambed materials than the adjacent habitat of the mainstem river. Side Slough Habitat -is located in overflow channels between the edge of the floodplain and the mainstem and side channels of the Susitna River.It is usually separated from the mainstem and/or side channel s by well vegetated bars.An exposed alluvial berm often separates the head of the slough from mainstem discharge or side channel flows.The controlling streambed/bank elevations at the upstream end of the side sloughs are slightly less than the water surface elevations of the mean monthly discharges of the mainstem Susitna River observed for June,July,and August.At intermediate and low-discharge periods,the side sloughs convey clear water from small tributaries and/or upwelling groundwater.These clear water inflows are essential contributors to the existence of this habitat 108 .... ""'" - - ""' r I . type.The water surface elevation of the Susitna River generally causes a backwater to extend well up into the slough from its lower end.Even though this substantial backwater exists,the sloughs function hydraulically very much like small stream systems and severa 1 hundred feet of the slough channel often conveys water independent of mainstem backwater effects.At high discharges the water surface elevations of the mainstem river is sufficient to overtop the upper end of the slough.Surface water temperatures in the side sloughs during summer months are principally a function of air temperature,solar radiation,and the temperature of the local runoff. Stage -The height of the water surface above an established datum plane.Stage can be converted to true water surface elevation if the observations are converted into project datum. Streamflow -Same as discharge but refers specifically to side channel, slough and tributary habitats whereas discharge denotes streamflow in mainstem habitats.See Discharge. Tributary Habitat -Consists of the full complement of hydraulic and morphologic conditions that occur in the tributaries.Their seasonal flow,sediment,and thermal regimes reflect the inte- gration of the hydrology,geology,and climate of the tributary drainage.The physical attributes of tributary habitat are not dependent on"mainstem conditions. Tributary Mouth Habitat -Extends from the uppermost point in the tributary influenced by mainstem Susitna River or slough backwater effects to the downstream extent of the tributary pl ume which extends into the mainstem Susitna River or slough. Upland Slough Habitat -Differs from side slough habitat in that the upstream end of the slough does not interconnect with the surface waters of the mainstem Susitna River or its side channels even at high mainstem discharges.These sloughs are characterized by the presence of beaver dams and an accumulation of silt covering the substrate resulti ng from the absence of mai nstem scouring di s- charges. Upper Reach (of the Susitna River)-The segment of the Susitna River between Devil Canyon and the headwaters (See also lower reach and middle reach). USGS Water Year -The USGS water year runs from October to September and the years designation is determined by the end of the period.The 1983 water year occurs from October 1 of 1982 to September 30 of 1983. 109 .... - ..", 6.0 CONTRIBUTORS ~PROJECT LEADER Aquatic Habitat and Instream Flow Project Leader Christopher Estes PRIMARY AUTHORS Theresa Keklak ~Tim Quane REPORT COORDINATORS Christopher Estes Douglas Vincent-Lang Tim Quane EDITORS Christopher Estes if'.ij~Douglas Vincent-Lang DATA PROCESSING Allen Bingham Camille Stephens ~.tm Theresa Keklak Kathrin Fosel Gail Heineman Donna Buchholz Alice Freeman DATA COLLECTION Pat Morrow....Theresa Keklak Tommy Wi throw Chris Kent Jody Miller Isaac Quera 1 DRAFTING Sally Donovan TYPING Skeers Word Processing 110 7.0 ACKNOWLEDGEMENTS Funding for this study was provided by the State of Alaska,Alaska Power Authority.Input into study design was provided by LW.Trihey & Associates. 111 - - ~I - aquatic studies phase II data report.
