' INTRODUCTION· I. :I : ~ 1.0 INTRODUCTION 1.1 Background Water quality concerns of the Bradley Lake Hydroelectric Project in the lower Bradley River are associated with project operation. These concerns were addressed in the FERC Bradley Lake License Application, and accompanying documents using estimates of present water quality conditions and predicted conditions under project operation. However, for project design and finalization of site specific mitigation, more specific data were required. Hence, additional studies were undertak- en to verify estimates relative to existing conditions, and to allow improvement in predictions of the lower river water quality under project operation. 1.2 Study Objective The objective of this study is to collect additional field data to describe existing water quality conditions, and improve reliability and resolution of predictions of these conditions under project operation. Specifically, the program included: 1. Collection of streamflow data on the North Fork of the Bradley River. 2. Collection of surface and intragravel water temperature data in spawning areas presently utilized in the lower Bradley mainstem. 3. Observations of ice processes in the lower Bradley River. 4. Collection of information on particle size and percent fines in the lower Bradley River to characterize substrate and sediment deposition during low flows. BR Water/107 1-1 1.3 Summary of Study Results Both surface and intragravel water temperatures respond to air temper- ature fluctuations. Intragravel temperatures are slightly warmer than surface water temperatures, they change rapidly with changes in surface water temperatures. water appear to be more Exchange between surface and intragravel rapid in Tree Bar Reach. Because of temperature compensation by embryos and the small magnitude of water temperature changes predicted under project operation, dates of emergence are expected to be within natural variation of emergence and outmigration for Kachemak Bay Pink Salmon stocks. Thus, water temperatures under project operation are not expected to alter production of pink salmon in the mainstem Bradley River. Substrate studies in the lower Bradley River focused on the percent of fines contained in spawning areas. The amount of fines present in Riffle and Tree Bar Reaches were within the tolerance level for spawning salmonids. Riffle Reach accumulated more fines in spring sampling than Tree Bar Reach. Greater differences in the percent of fines would probably have been observed without the high flows that occurred in late January. Under reduced flows during project operation there was concern that sediments may accumulate in Riffle Reach that could adversely affect spawning and incubation habitat. Spawning habitat under project operation will be located in the central portion of the channel. These areas experience higher velocities under low flows than presently utilized spawning areas which are generally located along the river margins. It is expected that new spawning areas will exhibit fewer fines than existing spawning areas. BR Water/107 1-2 SECTION 2.0 METHODS 2.0 METHODS 2.1 Field Methods 2.1.1 North Fork Gaging Continuous stage and temperature data were collected on the North Fork of the Bradley River using a Datapod model DP 211 recorder. The recorder was set to record average values every 6 hours. The recorder was installed temporarily, on December 19, 1984, in a pool approximately 100 yards upstream from the confluence of the North Fork with the Bradley River (Figure 1). A large discharge at the end of January partially dislodged the gage causing a shift in the transducer location. The unit was removed from the water on March 6 and reinstalled in its permanent configuration on March 21. To calibrate equipment, discharge measurements were taken on December 10, 1984 and May 2. Measurements were prevented during most other site visits because snow and ice conditions prevented access to the flow measurement site. The measurements were taken near the down- stream end of the pool containing the gage, but above the hydraulic control. The cross section at the measurement location was surveyed on May 2. Some points on the cross section were estimated because ice and snow were present, however, points would not affect the area and wetted perimeter until the discharge exceeded about 80 cfs during the open water season. The minimum elevation of the hydraulic control was also measured. 2.1.2 Lower Bradley River Temperature Gaging Continuous surface and intergravel water temperatures were collected in the Riffle and Tree Bar Reaches of the lower Bradley River using Datapod model DP 2321 recorders. The location of these recorders are shown in Figures 2 and 3. The recorders were set to record the maximum, minimum and average temperatures over 6 hour intervals. The BR Water/107 2-1 surface water temperature probe was fixed within 3 inches of the bed; the intergravel probe was located 18 inches into the gravel in a perforated probe. 2.1.3 Ice Observation Methods Aerial reconnaissances to evaluate the lower Bradley River ice pro- cesses and the Kachemak Bay/Bradley River ice interactions were conducted by flying over the river to observe ice conditions and to collect photographs. Ice thickness was measured and ice characteris- tics were documented during ground reconnaissances; the effects of tidal inflow.on the ice processes at selected sites were also inves- tigated. The dates and activities of the ice observation reconnais- sances are summarized below: Date November 13, 1984 November 20, 1984 December 17-18, 1984 March 7-8, 1985 March 20-23, 1985 May 2, 1985 BR Water/107 Activities Fly-over, photography, comprehensive ground reconnaissance Fly-over, photography, tide effect observation, ground reconnaissance Fly-over, photography, ground reconnaissance Fly-over, photography, comprehensive ground reconnaissance Fly-over, photography Fly-over, photography, ground reconnaissance 2-2 I >- <( cc ~ <( ::!: w J: 0 <( ~ w ~ <( ...J > w ...J 0 <( a: cc en w ... ...J ::§ 0 BRADLEY LAKE STUDY AREA SHOWING STREAM GAGE LOCATION FIGURE 1 G 3tin~l.:l-------___, 3E>VE> ~\f3W.s ·s-ersn aNV 'S38rn:k:f 3~ Vt:f3dVal 'S31cJWVS !N3Vii03S .:::10 SNOilV001 E>NIMOHS H~V3~ ACJUS ~V8 .33Hl .:::10 ~V~E>VIO ~ll V~3HOS 199:.1 1 I I OS 0 @ aBae waaJIS -s-ersn \J .JapJOoat~ a.rqBJadwa J. y SUO!~B001 DU!IdWBS e J9ABJ8E:J pOOMUOUOOfJ9PJV U) aoruds t::::tJ (l ' .. :""";•' ·'· ~~' £ 3~nE>I.:J .l t f t t l t t t f t t t t t t t t t t t i 3E>VE> ~V3l::llS-·s·e>·s·n aNv L.....,.-.--\\::\,t t ' ' ' ' ' ' ' t t ' 9 "J.l. t t t t t t t t t t t 'S380l::ld 3l::lnl Vl::l3d~31 . ¢i t t t t t t t t t t -. ~ ¢~( t t t t t t t t t t 'S31d~VS 1N3~103S .:JO 9 <§ .w t t t t t t t t t t t Q 9 -t t t t t t t t t t ; SNOil V~01 E>NIMOHS Gi <§. / Q ., -~ t t t t t t t . - - -t t ~j t t t t t t ~fit'' tttttt ttt ~Vl::IE>VIO ~11V~3H~S !§ ~ ~ ¢it!ji t t t t t t t ~ t t , -l~<§ti tttttftt tt -~ $' ~~ t t t t t t t t , ; ~ <§ <!j. . : t t t t t t * t t t . ::.:.~:· : .. tj(j~r.j· ttttt.tt .... ,, ... , fj (.j ~,. -· L "J.l. ~-···.-·:·-t t t t t .... t .. t t ..

The Bradley River substrate ranged from 100 lb. boulders to 0.001 mm effective diameter particles. Due to this large size range a freeze core sampling system was developed. The system consisted of a tripod and jacking system, pipe probes and liquid co 2 (Figure 4). By freezing the substrate, an undisturbed and unwashed sample could be removed from the stream bed (Figure 5). In addition, accurate depths could be measured by splitting the sample vertically. The sample probe consisting of a 24 inch long, 1 inch diameter pipe with a pointed, sealed end was driven into the substrate to a depth of 18 inches. Liquid C0 2 was injected into the pipe via a 1/2 11 steel pipe and allowed to flow until the 20 lb bottle was empty. Pressure was regulated to maintain flow of co 2 and to allow the freezing to occur over a 10 to 14 minute period. After the freezing was complet- ed, the tripod and jacking system were used to extract the sample. Typically samples were 6 to 9 inches in diameter and 18 to 20 inches long. This size provides a large enough sample to meet the recom- mended minimum weight established by ASTM. Immediately after the sample was removed the diameter and length were measured. The sample was then wrapped in plastic, taped and placed in a burlap bag for transport. BR Water/107 2-3 For analysis the still frozen samples were placed over boxes divided into 3 compartments, each about 6 inches wide. The excess length of sample was placed into the compartment containing material farthest from the surface material. Each compartment was bagged separately and returned to Anchorage where sieve analyses were performed. 2.2 Analytical Methods 2.2.1 North Fork Discharge and Temperature Data were extracted from the data storage modules and were reduced to provide mean daily stages and temperatures. The recorded stages from the temporary installation, the partially dislodged configuration, and the permanent installation, were adjusted to reference stage data to the same datum. Additional adjustments were made to the data to eliminate ice staging effects. The few measured discharge and stage were developed into a rating curve at the site. This was used to calculate provisional daily discharge data from the adjusted stage data for the periods December 19, 1984 to March 6, 1985 and March 31 to May 2, 1985. The provisional discharges were averaged for each month and the January average compared with the difference between the January averages of the U.S .G. S. provisional data for their Bradley River gages at tidewater and the lake outlet. The topographic charac- teristics of the two drainage basins contributing the flow were compared. The mean daily air temperatures were tabulated and plotted. The water temperature records during several periods in March and April were affected by air temperatures due to shallow or no water over the sensor. Hence water temperatures during these periods were estimated. BR Water/107 2-4 r I r r I II II I TRIPOD EQUIPMENT USED TO EXTRACT" FREEZE CORE SAMPLES .___-------FIGURE 4 I ..

Data on one of the two data storage modules for Riffle Reach from December 9 to March 6 was unretrievable from the module. The collec- ted data were tabulated and plotted. 2.2.3 Sediment Sample Analysis 2.2.3.1 Laboratory Techniques Sieve analyses were performed on all samples. In addition, selected hydrometer tests were performed on selected samples taken in December. ~he sieves performed were conducted generally in accordance with ASTM Test Method D-422. The variations from the ASTM method are as follows: 1. All rocks large enough to be retained on a 3" sieve were individually weighed and recorded. Rocks from the December 1984 sampling program were also measured along three mutually perpendicular axes with one axis incorporating the extreme maximum dimension of the rock. 2. All sieves smaller than the #16 were washed. The sieve data were corrected to account for the oversize material and to discount large rocks protruding from the main core of the sample. The correction was based on a plot of rock weight vs. longest dimen- sion and judging an average percentage protruding from the body of the sample. Corrections used are as follows: BR Water /107 2-5 Rock Weight (lb) less than 1.5 l. 505 to 2. 7 5 2.755 to 6.5 6.505 to 20* percent weight used in calculating sample distribution 100 75 50 30 * judgement was used on rocks over 20 lb based on actual sample and rock position 2.2.3.2 Data Analysis Analyses of sediment data consisted primarily of parametric statis- tical tests. Specific procedures and assumptions followed Sokal and Rohlf ( 1969). Tests that were performed included Student's T-test, analysis of variance (randomized block design), and Mann-Hhitney two-sample test. A minimum confidence of 10 percent was used to accept or reject the stated null hypothesis. BR Water/107 2-6 ' J! SECTION 3~o· RESULTS ll: 3.0 RESULTS 3.1 Climatic Conditions Climatic data are tabulated in Appendix A for the winter of 1984-85 and compared with winter conditions in previous years (Figure 6). National Weather Service data were obtained from the Arctic Environ- mental Information and Data Center and from the weather service in Homer. 3.2 North Fork Discharge and Temperature 3.2.1 North Fork Stage Data Collected stage data, adjusted to a constant datum, are shown in Figure 7. These data are tabulated in Appendix A. The general trend from December 20, 1984 through the end of January was a gradual recession. Several short duration peaks resulted from precipitation events during the relatively warm month of January. One peak (December 17-29) was not related to precipitation, but was a result of an ice staging effect. The stage was adjusted to the general recession shape during this period for the purpose of calculating flows using the rating curve (Figure 8). Warm weather combined with precipitation caused a relatively large flood at the end of January. Following the large, short-duration flood, a uniform recession in stage continued into February when cold weather caused another ice staging effect beginning February 7. This ice staging effect was removed from the anticipated recession curve for the calculating discharges using the rating curve (Figure 8). flow recession was believed to continue into late March. BR Water/107 3-1 purpose of The general Two short periods of increased stage at the end of March and beginning of April were likely caused by ice formation and were modified for discharge computations. A period in mid-April was also modified. March to May the stage was estimated to decline followed by a gradual stage increase. 3.2.2 North Fork Discharges The provisional discharges for the North Fork Bradley River during the period of record are shown in Figure 9. The data are tabulated in Appendix A. The flood at the end of January was estimated to be approximat.ely 145 cf s. In January, the mean North Fork discharge of 23.5 cfs represented less than half of the estimated mean monthly flow of 66 cfs in the unregulated portion of the basin (that part not used for power generation). Although the North Fork drainage basin flow is estimated to be about 90 percent of the total unregulated basin flow (about 85 percent when the Middle Fork is diverted), it would be less during the winter, as explained below. Above 2,000 ft. elevation most winter precipitation falls as snow and therefore does not contribute to the discharge of the North Fork. As a result only the area below 2,000 ft. elevation (approximately 50 percent of the drainage basin) was assumed to contribute flow to the North Fork. A review of the provisional discharge records for the Middle Fork Bradley River (Appendix A) illustrates this point. The percentage contribution of the North Fork to the total unregulated flow would thus be expected to vary from about 40 percent to 90 percent or more during the year, depending on climatic conditions. 3.2.3 North Fork Temperatures The provisional North Fork water temperatures are shown in Figure 10.

The water temperatures during the period March 21 through May 2 were more variable than the previous period. The difference in temperature characteristics may result from the location of the temperature sensor. The temporary and permanent installation of the temperature sensor monitors the near surface temperatures in the stream at low discharges. At low discharge, the water temperature appeared to respond more readily to fluctuations in air temperature. Some data were negative during cold weather periods; these data were deleted from Figure 10 and the table Appendix A. The dislodged sensor was about 2 ft lower than it had been in the tem- porary installation; it was thus measuring the water temperature deeper in the pool and it varied little with changes in air tempera- ture. 3.3 Lower Bradley River Temperatures Surface and intragravel water temperatures in Tree Bar and Riffle Reaches of the lower Bradley River are shown in Figures 11 and 12. These data, and the daily minimums and maximums for the period, are tabulated in Appendix B. The mean daily surface water temperature in Tree Bar Reach ranged from 1.8° C to -O.l°C. Maximum and minimum recorded temperature during the period were 2. 0°C and -0.1 °C. A diurnal temperature fluctuation of over 1.0°C was observed during some warm days in April. Intragravel water temperatures in Tree Bar Reach were generally 0.2-0.3°C warmer than the surface water temperatures. A temperature lag was evident only in cases where the surface water temperature changed rapidly, such as in December. The intragravel water tem- perature changed every 6 hours with changes in surface water tem- perature. The minimum and maximum intergravel temperatures during the period were -O.l°C and 2.0°C. BR Water/107 3-3 Surface water temperatures in Riffle Reach were very similar to those in Tree Bar Reach. Diurnal temperature fluctuations were evident in late April when the weather had warmed. Minimum and maximum surface water temperatures during the period were -0.3°C and 2.6°C. Intragravel water in Riffle Reach appeared to change less readily with changes in surface water than did Tree Bar Reach, and thus more of a lag was evident than at Tree Bar. With constant surface water temper- atures intragravel water temperature was 0.2 to 0.3°C warmer. As surface water temperatures warmed in April, intragravel temperatures lagged by 0.1 -0.2°C for several days in a row. Minimum and maximum intragravel temperatures were 0.2°C and 1.4°C for the period. 3.4 Lower Bradley River Ice Observations A summary of ice observations in the Lower Bradley River during the 1984-1985 winter are provided in Table 1. The locations referenced are shown in Figure 13. below. 3.4.1 Ice Development Results of these observations is provided Ice development in the Bradley River is influenced by both tidal and riverine ice formation. Ice floes are created and transported during the tidal cycle and affect the ice formation in the lower river. In the Upper Bradley River, outside of tidal influence, ice develops initially on channel margins in still water reaches.

During high tides, Kachemak Bay water floods the tidal flats. As the tide recedes, shallow ponds are formed which freeze into ice sheets. The ice sheets are transported during the next high tide, sheet ice is formed each tidal cycle. The limits of ice transpor- tation during a tidal cycle extended from about 2 miles southwest of the Russian Village at low tide to Eagle Pool. Unobstructed ice movement at higher tides could be expected to extend to just down- stream of Tree Bar Reach. During freeze-up in the still water reaches of the Bradley River, ice begins to develop along the shore and in very shallow water. The shore ice forms a long border attached to the river bank and grows laterally out over the channel. In the shallows, ice anchors to the channel bed where water levels are receeding and velocity has slowed. This anchor ice was observed at Tree Bar Reach, Riffle Reach and as far downstream as the gravel bar at the head of Eagle Pool. The shore ice and anchor ice are not transported during the tidal cycle. In the 1984-1985 winter, ice thicknesses ranged roughly from 4 to 6 inches by early February. A continuous ice cover is formed to culminate the development of tidal and riverine ice. Hummocked ice characterized the river downstream of Fox Farm Creek. Upstream from Riffle Reach, mid-channel open leads existed where water velocities were high, such as at Tree Bar Reach. On March 8, the ice was 15 to 18 inches thick topped with 4 to 6 inches of snow and slush. During periods of continuous ice cover, hinge cracks developed from Riffle Reach to the bend downstream from Tree Bar Reach. The ice hinged downward from the shore fast ice at low tide. While at high tide, the ice hinged upward while remaining fastened to the shorefast ice. The ice thickness and continuity kept the water from flowing into the lower area by the bank. Further downstream, where the tidal range is greater the hinge cracks were severed. The mid-channel ice floated within the channel banks while water overflowed into the tidal flats (Figure 14). BR Water/107 3-5 Tidal overflow of grounded ice increased ice thicknesses by developing snow ice. By late March, the thicknesses above the maximum tide zone (Transect 4 Tree Bar) ranged from 12 to 18 inches. In the tidally influenced areas, ice depths to 2 feet were common. Although tidal overflow of the ice was not observed during aerial or ground recon- naissances, silt was observed on exposed ice surfaces in Eagle Pool and Riffle Reach. The sediment source is assumed to be tidal waters as the river sediment load is near minimum during the low winter flows. 3.4.2 Breakup Breakup in the Bradley River is also influenced by both the tidal cycle and riverine processes. The tidal cycle is the primary mecha- nism for ice breakup in the lower river. Further upstream, the ice cover melts as ambient temperatures and river discharge increase. Breakup was observed from March 20 to March 23, 1985. In the lower river, the ice cover disintegrates from the mouth in the upstream direction. The ice floes are transported into Kachemak Bay by the outgoing tide. Upstream of the tidal breakage front, melting enlarges open leads in the ice cover. The shorefast ice melts progressively. On March 20-23, 18 inches of shore ice was observed on the gravel bars in Riffle Reach. By May 2, the shore ice depth had decreased to 6 inches. Meanwhile, the open leads enlarge and become continuous; ice floes are formed as the open leads join. Most ice floes are carried downstream into Kachemak Bay by the Bradley River current and by tidal action. However, some ice floes ground on shore ice, gravel bars, or on top of the banks. On May 2, 2 ft thick ice floes were grounded on the shore ice on the gravel at Riffle Reach; these had become frozen to the shore ice and a few had two layers of ice floes on the shore BR Water/107 3-6 I MID-CHANNEL ICE IN BRADLEY RIVER DURING HIGH TIDE, EARLY MARCH, 1985 ..___ _______ FIGURE 14 ice. Downstream from Riffle Reach, the Bradley River was free of ice. The shore ice and grounded ice floes are the only remnants of the continuous ice cover. 3.5 Lower Bradley River Sediment A summary of the sediment sample characteristics in Tree Bar and Riffle Reaches are provided in Tables 2 and 3. Grain size curves for all samples are provided in Appendix C. Substrate was classified visually in the Bradley River for inclusion in the habitat simulations conducted for. the feasibility studies, i.e. Instream Flow Report (Woodward Clyde & Assoc.). Since the Bradley River remains turbid throughout the year, accuracy of visual estimates required verification. Results of sieve analysis were compared with visual estimates of substrate size (Table 4). Visual evaluation generally classifies substrates one class higher than results of sieve analyses. Although the samples from the upper zone were used in the comparison, a smaller substrate size for the sieved samples is to be expected. Sediment samples collected during this study indicate that the rela- tive abundance of fine silts (less than 0.003 in. diameter) varies considerably between the two reaches, between stations within the same reach, and between replicates at the same station. During the Decem- ber 1984 sampling period, the relative abundance of fine silts was significantly greater at Riffle Reach than at Tree Bar Reach (T-test, T-3.34, P-0.01). This difference existed in the means for the reaches as well as at all three depths. During the March sample period, the relative abundance of silts at both reaches had increased slightly; however, the difference was not statistically significant from December (T-test, T=0.59, P-0.10). In December 1984 at Tree Bar Reach, 1.0 percent of the substrate consisted of fine silts, while in March, this had increased to 1.2 BR Water/107 3-7 percent. Riffle Reach demonstrated a similar increase, averaging 4.5 percent in December 1984 and 4.8 percent in March. The difference in the relative abundance of fine silts between the two reaches in March was significant (T-test, T-6.34, P-0.01). Considerable variation in the relative abundance of fine silts existed within the two reaches. During December 1984, the relative abundance of fine silts at Tree Bar Reach ranged from 0.4 to 0.8 percent at the surface and from 0.4 to 3.0 percent 18 inches below the surface. Greater variation was found at Riffle Reach during December 1984 where fine silts comprised 0.7 to 7.8 percent of the surface material and 0.9 to 12.1 percent of the material 18 inches below the surface. A similar level of variation existed in March. At Tree Bar Reach, fine silts represented 0.3 to 2.7 percent of the surface material and 0.4 to 2.7 percent of the material 18 inches deep. At Riffle Reach, 0.8 to 6.8 percent of the material at the surface consisted of fine silts and 5.2 to 7.1 percent of the material 18 inches deep consisted of fine silts. In some cases, this level of variability existed at a single station in the same month. BR Water/107 3-8 r Table 2.

Estimated surface water temperatures from April through August are anticipated to be similar to, or slightly warmer than, natural temperatures. Warmer water temperatures are expected from Bradley Lake outflow during this period as the decreased volume of water is more quickly heated by warm air temperatures over present conditions. From September through freezeup in November, temperatures are anticipated to be slightly cooler with a decrease of 2°C or less as smaller flows will cool relatively faster than current flows in response to air temperatures. Anticipated temperatures and flows for December through March are similar to natural conditions. 4.1.2 Salmon Emergence Changes in surface water temperatures can alter intragravel water temperatures which are important to incubation of salmon embryos. The rate of incubation is closely related to water temperature. Warmer or cooler water temperatures in the intragravel environment could, respectively, accelerate or retard embryo development, changing emergence time. Of the salmon species using the Bradley River, pink salmon have the highest potential for changes in emergence timing under project operation. Pink salmon spawn in mainstem habitats where changes of water temperatures are expected. Pink salmon generally spawn in the Bradley River during the second half of August, with fry emerging during April of the following year. Cooler water temperatures predicted for the Bradley River during the fall months under project operation may slightly delay pink salmon BR Water/107 4-1 emergence timing. However, the emergence date is not expected to exceed the natural variation in emergence and out migration. In Kachemak Bay, the annual variation of pink salmon emergence and out migration timing ranges from late March through May (Tom Schroeder, ADF&G Homer, per. comm 1985). Coho and chum salmon emergence timing are not expected to be affected by an altered temperature regime in the Bradley River. 4.1.3 Intragravel Temperature There are three factors contributing to intragravel water tem- peratures; infiltrating surface water; groundwater or subsurface flow; and ground temperature. The relative contribution of each of these components varies on a site specific basis. However, changes in surface water temperatures are not expected to result in changes in intragravel water temperatures of the same increment. The influence of groundwater or subsurface flow and ground temperature would dampen the surface water temperature changes effect on intragravel tern- peratures. In Tree Bar Reach, intragravel temperatures are slightly warmer than surface water temperatures and do not appreciabilly lag surface water temperatures. This indicates that groundwater has little influence on intragravel temperatures in this reach. Changes in surface water temperatures under project operation would likely result in similar changes in intragravel water temperatures. In Riffle Reach, intragravel water temperatures are slightly warmer and do not respond to changes in surface water temperatures as rapidly as Tree Bar. This indicates that subsurface flow and ground tempera- ture may buffer intragravel temperatures in this reach. 4.1.4 Verification of Study Conclusions Experimental studies show that there is a compensation mechanism for eggs developing at colder temperatures. Development rates of embryos 0 0 are expressed in temperature units. (T. U. = 1 above 0 C for a 24 BR Water/107 4-2 r hour period). Total temperature units required for emergence, or complete yolk absorption, have been estimated for Skagit River, Washington pink salmon populations (Graybill et al. 1979). 0 In the Skagit River experiments, mean temperature differences 1 C or less resulted in 2-5 days difference in incubation time to complete yolk absorption (CYA).

At lower temperatures, fewer T. U. 's were required to complete development, thus emergence time remained approximately the same. The variation in total T. U. 's at low temperature shown in a few studies on pink salmon (Graybill et al. 1979) suggests that the summation method is not an accurate predictor for this species as well. There presently are insufficient data on pink salmon incubation to develop the type of model Alderdice and Velsen (1978) developed for chinook salmon. 4.1.5 Conclusions-Pink Salmon Analysis Pink salmon in the Bradley River are expected to exhibit temperatur~ compensation and slight delays in emergence timing if project BR Water/107 4-3 operation results in projected lower water temperatures during the fall. The period of temperature data collection was not sufficient to compare T.U.'s available for incubation during 1984-1985. Since data on water temperatures, intragravel temperatures, and incubation requirements lack sufficient resolution for a detailed analysis of temperature units, an alternative analysis was undertaken. Mean monthly surface water temperatures can be used to approximate the mean incubation temperature. Pink salmon spawn in the Bradley River primarily during the last two weeks in August, with fry emerging during April of the following year. If the predicted mean monthly temperatures for August through April are used to approximate the mean incubation temperature, the pre-project mean incubation temperature is 2.2°C, while the with-project mean incubation temperature is 1.9°C. A difference of 0. 3°C should not have serious impacts on emergence timing or fry survival. 4.2 Lower Bradley River Ice Observations Lower flows under project operation may result in increased ice thickness during winter. Since the volume of water will be less in the fall, water temperatures will cool more rapidly. Stream flows will remain fairly stable throughout the winter, causing the water to remain in contact with the ice. This will allow ice to continue to grow throughout the winter. As a result, thicker ice may develop during project operation. Steady winter stream flow in the mainstem should, however, contain sufficient velocities to prevent anchor ice formation. As currently exists, with receeding streamflow and spawning occur in the high flow margins of the channel, anchor ice growth may result in embryo mortality by freezing redds. During the pre-emergence studies in March 1984, smaller, less developed embryos and fry were found in areas influenced by ice (WCC 1984). BR Water/107 4-4 I The relative impact of the potential for increased ice growth is anticipated to be small. There will be a much smaller number of frozen redds during project operation than are currently experienced, since most of the redds which currently freeze are in areas that will be unavailable with project spawning flows. Much more spawning will take place in the thalweg of the channel, which will remain wetted during project operation. 4.3 Sediment 4.3.1 Siltation Siltation is an important consideration in evaluating spawning and incubation habitat in the lower Bradley River. The Bradley River transports a relatively light load of suspended sediments for a glacial system. Most of these particles appear to remain in suspen- sion as long as velocities are greater than 0.5 fps. As the incoming tide slows the river flow velocities the depth and top width increase; silt particles are deposited over a broad expanse of the channel. As the tide recedes, the velocities increase. The normal flow velocities present in the main channel without tidal influence remove much of the silt from these areas and transport it downstream. Silt tends to accumulate in areas dewatered under low-tide conditions or in other low-velocity areas. In the Bradley River spawning occurs during the high-flow period. A major factor influencing production of spawning area is the effect of low winter flows on embryo survival. As flows decrease during winter, spawning areas may become dewatered or silted. Spawning areas presently utilized in the mainstem Bradley River are located along the margins of the stream as fast velocities during the high flow period preclude the use of the center portion of the channel. Many of these existing spawning areas are dewatered or have low velocities during the incubation period that result in sediment accumulation. Increased sedimentation may be detrimental to salmon populations. BR Water/107 4-5 4.3.2 Sedimentation in Riffle Reach Sediment deposition in Riffle Reach may be detrimental to salmon incubation. Sediment accumulates in this reach during the low winter flows. The heaviest sediment accumulations have been noted in de- watered and low-velocity areas. In previous years, depositions of silts up to 0.3 ft. were noted in dewatered areas in Riffle Reach. Deposition observed in spring 1985 was notably lighter. Late January 1985 high-flow events may have removed much of the sediment, dis- torting the results of the substrate samples from "normal conditions". Figure 15 presents the percent fines from Riffle Reach substrate samples. Temperature data collected in Riffle indicates that exchange between intragravel and surface waters is not as efficient as in Tree Bar Reach. This is indicative of streams with higher levels of sedimentation. Pre-emergent sampling conducted in March 1984 found fewer live eggs and alevins in Riffle Reach than at Tree Bar Reach. Stations 1, 2 and 3 in Riffle Reach generally sampled existing spawning areas, while Stations 4 and 5 sampled spawning habitat which would become available under project operations. (High velocities during high summer flows preclude its use presently). These stations had lower percent fines in upper zones in March as compared with Stations 1 and 2. Since the potential spawning habitat is located more in the center portion of the channel, it experiences higher velocities (even under low flows) than the existing spawning habitat. 4.3.3 Sedimentation in Tree Bar Reach Substrate samples collected in Tree Bar Reach show little difference between percent fines in the surface layers in December and March. Since this reach is generally not influenced by tidal backwater, this is to be expected. Water temperature data collected in Tree Bar Reach indicate good exchange between surface and intragravel water. This indicates that the substrates are relatively free of silts and sands.

Critikos by NORTHERN TECHNICAL SERVICES, INC • The Bradley River is currently being monitored at three locations for water temperature. As part of the 1985 environmental monitoring program instruments maintained at these locations are serviced; data storage chips retrieved; data recovered form chips (by Dryden and Larue); and the summarized data is transmitted in report from to Stone and Webster Engineering Corporation. This is the first in a series of reports covering the water quality task and includes the data obtained from the initial servicing of water quality instruments. The temperature sensors were serviced August 1 and 3, 1985. It was necessary to use a helicopter to reach the North Fork site. A summary of the servicing follows: 1. Tree Bar Reach, serviced August 1, 1985/1700 hrs. Unit appeared to be functioning properly; "short dump" performed. Data storage module (DSM) was replaced and initialized for August 1/1800 hrs, in agreement with the previous DSM. Some of the new dry cell batteries yielded the "Lo Bat" indicator, so these were replaced with a second set. The "ammo box" shelter was painted bright orange for easy location on the next field service visit. The unit appeared to be functioning properly after servicing. 2. Riffle Reach, serviced August 1, 1985/1800 hrs. Unit yielded no display; batteries were apparently expired. DSM and batteries were replaced and initialized for 2400 hrs/August 1, Channel 1 read 11 -05.0C" during short dump at startup; replacement of the Datapod and/or a probe may be required. The "ammo box" shelter was painted bright orange. This unit should be re-serviced as soon as possible.

Critikos by NORTHERN TECHNICAL SERVICES, INC. 750 W. 2nd Avenue Anchorage, Alaska 99501 The Bradley River is currently being monitored at three locations for water temperature. As part of the 1985 environmental monitoring pro- gram, instruments maintained at these locations are serviced; data storage chips retrieved; data recovered from chips (by Dryden and Larue); and the summarized data is transmitted in report form to Stone and Webster Engineering Corporation. This is the second in a series of reports covering the water quality task and includes the data obtained from the servicing of water quality instruments on August 31, 1985. The data is presented in three attachments: Attachment I -Riffle Reach Attachment II -Tree Bar Reach Attachment III -North Fork Bradley River The data covers the period from August 1-31, 1985. A summary of the servicing record is presented below: 1. Riffle Reach. during mid-August This unit was visited by the fisheries field crew at which time it was determined that the unit malfunction reported at the last servicing was in one of the probes. The probe was later replaced and the unit appeared to function properly for a short time. However, the Datapod itself developed a fault in which Channel 2 consistently read "-05. OC", regardless of which probe was used. During the 31 August field service visit, the entire unit (including the probes) was recovered and brought to Anchorage for repair. Dryden and Larue repaired the unit and it is ready for rede- ployment at the next servicing date. 2. Tree Bar Reach, serviced 31 Aug 85/1015 hrs.

Critikos by NORTHERN TECHNICAL SERVICES, INC. 750 W. 2nd Avenue, Suite 100 Anchorage, Alaska 99501 The Bradley River is currently being monitored at three locations for water temperature. As part of the 1985 environmental monitoring program instruments maintained at these locations are serviced; data storage chips retrieved; data recovered from chips (by Dryden & LaRue); and the summarized data are transmitted in report form to Stone and Webster Engineering Corporation. This is the third and final report covering the water quality task. The report covers the period from August 31 to December 28, 1985. The data are presented in four attachments: Attachment I -Riffle Reach, October 28 -December 28, 1985. Attachment II -Tree Bar Reach, August 31 -October 28, 1985. Attachment III -Tree Bar Reach, October 28 -December 28, 1985. Attachment IV -North Fork Bradley River, August 31 -October 28, 1985. A summary of the servicing record is presented below. Riffle Reach, serviced 28 October 1985 I 1215 hours This unit had been removed from the field on 31 August 1985 for servic- ing. The DMS was installed, initialized and tested on the evening of 27 October 85, and appeared to be functioning properly. The unit was reinstalled at its original location. The "ammo box" shelter was wired to the same tree as before, and the cable was wired to the stake on the bank. It was not possible to drive the perforated instrument's stake (which housed the thermistors) into the streambed, due to icy conditions on the streambank. The unit appeared to be functioning properly after servicing. Riffle Reach, serviced 28 December 1985 I 1145 hours The unit appeared to be functioning properly; "short dump" test was performed. Data storage module (DMS), batteries, and dessicant capsule 2 were replaced. The unit was initialized for noon, 28 December 85. The Datapod appeared to be functioning properly after servicing. Tree Bar Reach, serviced 28 October 1985 I 1125 hours The Datapod unit appeared to be functioning properly, but the probes had been damaged; apparently by high flows and/or riverborne debris. The probe cables were still attached to the Datapod, but they had been pulled out of their protective casing, and were lying along the stream- bank in the snow. The casing was no longer attached to the Datapod's "ammo box" shelter. It was still firmly attached to the perforated stake, which was securely embedded in the streambed, under a few inches of water. The casing was full of ice which prevented the re- installation of the probes into the casing. The probes were returned to the river, and were taped to the outside of the casing, as a temporary solution. Various alternative locations for the Datapod were noted, both upstream and downstream. The data storage module (DMS) and the dessicant capsule were replaced. The "Lo Bat" indicator was displayed; the batteries were replaced and the unit was re-initialized. The unit appeared to be functioning properly after servicing. Consideration should be given to moving it to a less vulnerable location. Tree Bar Reach, serviced 28 December 1985 I 1130 hours The Datapod unit yielded spurious readings during the "short dump" test. The cables for both probes had been severed, and the cables had been twisted and damaged. The damage appeared to have been caused by ice and/or riverborne debris. The Datapod and the probes were brought to Anchorage for repair. The "ammo box" shelter was left on site; the stake, with the probe casing still attached, remained firmly embedded in the stream gravel. 3 North Fork, serviced 28 October 1985 I 1100 hours The unit appeared to be functioning properly; "short dump" performed. The DSM was replaced; the short dump indicated that no re-initialization was necessary. An accumulation of ice around the standpipe made it impossible to read the staff gauge. The batteries were not replaced. The dessicant capsules were replaced. The unit appeared to be function- ing properly after servicing. North Fork, serviced 28 October 1985 I 1050 hours The staff gauge at this site is a steel measuring tape attached to a plastic standpipe. The lower part of the tape (near the water surface) was missing; it apparently had been damaged by the ice accumulation noted during the 28 October 85 visit. It was estimated that the staff gauge reading would have been approximately 42 ± 3 inches. The Datapod unit appeared to be functioning properly. The dessicant capsules and batteries were replaced in both the Datapod and the stage-interface unit. The DSM was replaced. Some difficulty was encountered during re- initialization: at 1100 hours, 360 minutes remained until the first reading. Henceforth, the Datapod readings will be taken one hour earlier than they had been (i.e. the new schedule is: 0500, 1100, 1700, 2300 hours). Other than this, the unit appeared to be functioning properly. Status of Datapods at end of Project Riffle Reach: This dual-channel temperature recorder appears to be functioning properly, based on the analysis of the DMS. It was serviced at Dryden & LaRue in September and re-installed in the field in October. Tree Bar Reach: This dual-channel temperature recorder was returned to the Dryden & LaRue office in December 1985 for inspection and repairs. The probes were severely damaged, and the Datapod itself appeared to yield a spurious readout during the short dump test. Analysis of the 4 DSM's showed that the unit had actually ceased proper functioning sometime prior to the October visit. The instrument should be rede- ployed as soon as possible after repairs are complete. North Fork: This stage-temperature recorder appeared to be functioning properly at the October field service visit. However, the DSM that was installed in October and retrieved in December had recorded almost no data. During installation of this DSM, the initialization sequence (short dump and test burn) was performed properly; this was confirmed by Dryden & LaRue's reading of the DSM. It seems that the DSM stopped recording data shortly after installation; many error messages were recorded. This failure may be explained by a variety of possible causes: a) faulty DSM (Dryden & LaRue will analyze); b) incorrect installation (possible, but initialization was satisfactory); c) mechanical shock to the unit after the service visit, partly dislodging the DSM (the Datapod is at the bottom of a 30-ft unstable cut bank--possible that the unit sustained a blow by falling ice or rock); and/or d) corrosion, moisture, etc. (the Datapod has not been bench-serviced since at least 1984--also, during each of the 1985 field visits, the dessicant capsule inside the unit was saturated). The DSM installed in December 1985 appeared to be properly initialized; but this impression is now suspect and should be confirmed as soon as possible. 5 Data Pod Maintenance All data pods on the Bradley River System require servicing and repair. Several units were malfunctioning during the last period. The probes appear to have suffered damage from ice and floating debris. All data pods are being removed from the field for servicing. As soon as the units are repaired they will be returned to the field and reinstalled. Spare data pods are being obtained, so that in the future, a replacement unit can be installed should an inplace unit be malfunctioning. 6 Attachment I Riffle Reach Water Quality Data October 28
