A preliminary description of the proposed Newhalen River Hydroelectric Project is contained in the Bristol! Bay Regional Power Plan Interim Feasibility Assessment (Stone & Webster 1982). The project would entail the diversion of water into a canal at river mile (RM) 7 for conveyance to a powerhouse near the mouth of the Newhalen River. On the basis of a proposal by Dames & Moore, Stone & Webster was authorized by the Power Authority to complete a second year of baseline studies on the Newhalen River. The 1983 studies completed at river mile (RM) 13 complement those completed by Dames & Moore at RM 7 in 1982 (Dames & Moore 1982). The evaluations focused on temporal distrbution and enumeration of sockeye salmon (Onchorhynchus nerka) smolt and fry. Dames & Moore under contract to Stone & Webster had complete responsibility for 1982 field work and data analysis. As in 1982, Dames & Moore worked cooperatively with Patrick Poe of Fisheries Research Institute (FRI), University of Washington. Mr. Poe assisted in sample site selection, timing of sampling, mobilization, and sampling. There were several differences between the 1982 and 1983 study procedures and designs other than the change in sampling location. The 1982 study was designed primarily to sample spacial and temporal distribution of smolt and fry. After beginning the study, Dames & Moore was requested to collect data on the numbers of outmigrants, and as noted in their 1982 report (Dame & Moore 1982), the sampling program had limitations concerning the accuracy of this effort. Changes were made in the 1983 program study methods so that both spacial and temporal distribution and number of outmigrants could be adequately sampled. An additional request was made for conducting adult sockeye counts after this sampling effort began. The adult field effort was completed totally by FRI under contract to Dames & Moore. Another feature of the 1983 study was the inclusion of limited fish diversion and impingement survival tests conducted in the Newhalen River by Edward P. Taft of Stone & Webster. These studies were undertaken to obtain preliminary information on the potential effectiveness of a fish protection system at the canal intake to the hydroelectric plant. 2.0 ACKNOWLEDGEMENTS Financial support by the Alaska Power Authority made this study possible. Dames & Moore coordinated the field program and prepared the draft report. Stone & Webster added information relative to the fish diversion and impingement survival studies and oversaw the project effort. / As in 1982, FRI provided both personne! and an extensive equipment base in the Iliamna vicinity which allowed the project to be completed. Patrick Poe and Warner Lew provided a great deal of energy and expertise to the field program. FRI partially supported the program by allowing use of numerous gear types (boats, tanks, etc.) at no charge to the Power Authority. Eastside Net Shop (Bothell, Washington) again provided large wingless fyke nets of special design on very short notice. Trans Alaska Helicopters Inc. (helicopter charter) and Iliamna Air Taxi (room, board, and fixed-wing plane service) provided excellent service asin 1982. A special thanks is owed to two individuals. Dick Parent, Dames & Moore field engineer, provided his ingenuity in the mobilization and demobilization of sampling gear and camp facilities. Ward Johnson, FRI graduate student, assisted in scale reading and data evaluation leading to outmigration estimates. The cooperation received from the residents of the Nondalton, Newhalen, and Iliamna areas is also greatly appreciated. Finally, the spring field crew which gracefully put up with poor working hours and conditions for up to 7 weeks included William Blaylock, Dave Erickson, Ronn Griffin, John Isakson, Warner Lew, Dick Parent, and Patrick Poe. Various FRI staff members crewed the RM 22 adult counting station in 1983, and are also to be thanked for their contribution. 3.0 MATERIALS AND METHODS 3.1 SPRING METHODS The 1983 sampling goal was to begin sampling before the 1982 start date (May 10). Verbal notice to proceed in 1983 was received on May 3. A biologist and field engineer departed for Iliamna to begin preparation on May 5. The major portion of the freight, helicopter support, and three additional biologists arrived in Iliamna on May 9 to initiate full camp mobilization. The first outmigrant sampling started on May 11. The field program was terminated after 7 weeks (June 25). With funding reduced from 1982, a site less remote than RM 7 had to be selected in 1983. A major cost saving could be made if helicopter involvement was reduced. Therefore, the 1983 site had to be upriver of RM 7 and near the haul road between Iliamna/Newhalen and the landing on the Newhalen River which leads to Nondalton. The site selected on May 9 and 10 under relatively low water flows was about half way between Bear and Lover's Creeks at about RM 13 (Figure 1). This site had shallow enough water depths (to six feet) to accommodate the anticipated increase in water level to still allow our 9x9-foot net frames to fish later in the spring. 3.1.1 Net and Trap Sampling As in 1982, the Newhalen River proved to be a very dynamic system in terms of river flow. Initial flows in early May were about 5,000 cfs and these increased to about 15,000 cfs toward the end of June. A cross section of the RM 13 site and two measured flow levels in May and June is shown in Figure 2. Also noted are the locations of the six sampling stations sel- ected along the transect. As in 1982, RM 13 bottom conditions, consisting of large boulders, determined to a great extent, station location. Equal spacing of stations, due to bottom conditions across the river, was not possible.

The major changes were larger wingless fyke nets (9x9-foot) and two cables across the river to concurrently deploy them. One net was stationary while the other was moved to one of five remaining stations (see Figure 3). Bridal lengths on the upstream cable were made long enough to allow the two nets to fish about at the same position in the river. The larger new nets were 29 feet long with the 9x9-foot opening tapered to a 6-inch collar which lead from a 7-foot piece of flexible hose and into a floating live car. The progression of net mesh sizes (all stretch measure) was from 1.5 inches at the front, 0.5 inch in the midsection, to 0.25 inch at the cod end. With the exception of extra strengthening lines from frame to collar, these nets were similar to standard FRI surface tow-nets. This type of FRI gear is towed between two boats in lake studies. The larger 9x9-foot nets, upon arrival May 20, replaced a 3x9-foot net of 1/8-inch knotless nylon (0.25-inch stretch) used last year and in the first 4 days of sampling in 1983. - The sampling schedule with the two large cabled fyke nets was finally set as follows. The downstream cable (net was designated 9x9D) fished at a fixed position initially selected at Station 4 (Figure 3). This station existed from May 20 to June 5 when an east bank tree failed and the fixed cable collapsed. In moving to a new tree support, the fixed downstream station moved to the west about 30 feet at what might be labled Station "3.5" where the downstream net operated from June 6 through June 22. The upstream cable was initially used to fish all six stations to locate areas of smolt abundance in the river cross section. From May 24 to June 13 the upstream cable was operated in concert with the downstream cable and fished the same parts of hours as much as possible. In 1983, the 9x9-foot frames collapsed on three occasions. In 1982 the single cabled net was often moved each hour (Dames & Moore 1982). In 1983, with two cables, the upstream-cabled (mobile) net was usually moved once each sampling period with a focus from 9 p.m. to 4 a.m. each night.

Overview of RM 13 Site Showing Gear and Station Locations, 1983 Job No. 12023-013-20 8 Dames & Moore Figure 3 each sampling period provided numbers of smolt and fry caught that could more accurately be expanded to an outmigration estimate. Other gear types used in 1982 were again used in 1983 and included the floating inclined plane trap (IPT) and two smaller wingless-fyke nets (3x3-foot and 4x4-foot openings) of 1/8-inch knotless nylon (0.25-inch stretch). For a more complete description of these gear types see Dames & Moore (1982). The six sampling stations (numbered 6 to 1, east to west banks) along the cables crossing the river were 88, 150, 200, 250 290, and 320 feet, respectively, from the center of the east bank tower (Figure 3). There were about 20 feet between the center of the tower to the east bank itself. Stations 1 and 6 were sampled few times since preliminary 3x9-foot net catches and shore fyke nets near these locations caught few smolt and fry in 1983. The bulk of the mobile (upriver-cable) 9x9-foot net sets were at Stations 2, 3, and 5, while the fixed (downriver cable) net fished at Station 4 until gear failure on June 5 moved it to about Station 3.5. As in 1982, the mobile net system was fished most often in the period from 9 p.m. to 4 a.m. each night. Net handling in this period revolved around sets each hour and set durations usually involved an hour, 30 minutes, or 15 minutes, with the determining factor being the anticipated abundance of smolt and/or fry. Sampling times were reduced to intercept fewer juvenile fish during anticipated high abundance hours. Shore-mounted fyke nets--4x4-foot on the east bank and a 3x3-foot on the west or camp bank--were fished as in 1982. The only movement was to slowly bring the net closer to shore as the river rose in elevation (Figure 3). Generally the nets were kept in shore positions in about 2.5 feet of water. Both nets had floating live cars to reduce fish mortality. See further descriptions of the gear in Dames & Moore (1982). The inclined plane trap (IPT) was placed downriver about 300 yards from the RM 13 cables and fyke nets (Figure 3). The trap was located in mid-channel with anchors. See Dames & Moore (1982) for further details on the IPT used. To summarize, the following gear types and locations were fished in the spring 1983 studies at RM 13: Number of Gear Type Dates Fished Observations* 9x9-foot upstream net 5/20/83 to 6/13/83 174 9x9-foot downstream net 5/24/83 to 6/22/83 206 3x9-foot net 5/16/83 to 5/26/83 58 3x3-foot net (3x3 W) 5/13/83 to 5/21/83 238 4x4-foot net (4x4 E) 5/11/83 to 6/20/83 198 Inclined plane trap 5/16/83 to 6/22/83 276 *Times between observations ranged from minutes (between hour sets) to multiple hours depending upon gear type, concentrations of smolt or fry in the river, and gear availability. As in 1982, several parameters in addition to catch data for all species (including incidental resident fish) were recorded during index hours and throughout the day, as possible. These parameters included: (1) water and air temperatures (mean, minimum, and maximum every 4 hours in Data Pods-Model DP2321), (2) water level on a loaned USGS staff gage, and (3) general weather conditions. In 1983 a recording pyrheliometer (24-hour clock) was operated at RM 13 from May 16 through June 18. Fish processing consisted of species separation and counting with selected sockeye subsamples taken for length-frequency measurements. As requested by Alaska Department of Fish and Game (ADF&G), scale samples with length and weight measurements were taken from selected sockeye smolt at varying times during their outmigration. Scales were field-mounted on slides. Fry and smolt subsamples were preserved in buffered 10 percent formalin for possible future evaluation of smolt otoliths and other parameters. 10 3.2 SUMMER METHODS As in 1982, a field camp at RM 22 on the Newhalen River was established as the RM 13 camp was demobilized. In 1983 these facilities were operated in much the same way as in 1982 (Dames & Moore 1982) with the exception being only one inclined plane trap was operated about 100 to 125 feet from the east bank in a deep channel at this river cross section (see Figure 5 in Dames & Moore 1982). IPT operation was as described for 1982. More details of the adult counting operation by FRI can be found in Poe et al. 1983. Basically, 10-minute counts were made on each hour from each shore as conditions permitted. 3.3 SPRING ANALYTICAL PROCEDURES (NETS AND TRAPS) The procedures described in 1982 studies (Dames & Moore 1982) were again used to extrapolate and interpolate data on fry and smolt catches to both estimate an outmigration and define the horizontal distribution of these juvenile sockeye salmon. One major difference, however, existed in the data available to do these analyses. This was the existence, for most of the spring, of con- current 9x9-foot net catches both at an index station (initially Station 4) on the downstream cable and at varied stations on the upstream cable (usually Stations 2, 3, or 5; Figure 3). The catch data expansions were therefore completed with a more accurate representation of the relationships of the four main river stations to one another than in 1982. Stations 1 and 6 were seldom fished due to low fish catches there. In 1983 the mobile net was left through the peak migration hours (9 p.m. to 4 a.m.) at a single station while the index station was also fishing. In 1982 the single mobile net moved each hour to different stations during some days and was left on the RM 7 indexing station for the entire night on other days. at: 3.4 SUMMER ANALYTICAL PROCEDURES Due to the few fry caught in the IPT at RM 22 during the adult counting, no evaluation procedures were required for sockeye juveniles. Adult sockeye counts (10 minutes, each bank, each hour when possible) were expanded by multiplying both bank counts by 6 and adding them for each 24-hour day. Data expansion procedures are described in Poe et al. 1983. 3.5 GEAR LIMITATIONS As in 1982 (Dames & Moore 1982), similar gear limitations existed in 1983 with a few exceptions. The larger 9x9-foot nets most likely had less net avoidance by smolt and fry because of the bigger net openings than in 1982 (3x9- and 4x8-foot nets). In addition, green dyed net web was used in 1983 whereas the net web was white in 1982. Smolt most likely escaped capture on occasion even in these 9x9-foot nets as well as the 3x3- and 4x4-foot shore nets under lower velocity conditions at shore stations and to a lesser degree at Stations 1 and 6. Fry were probably unable to swim out of these nets at even these "lower" velocities. On the other hand, smolt probably did not pass through the net web in any nets while fry likely did escape capture in this manner. As the 1983 field season progressed, the 9x9-foot nets sagged in the cod ends, allowing bulges to occur in the net web just in front of the collar leading to the flexible 6-inch pipe. This also occurred in 1982. With a more distinct net bulge, along with higher velocities as the spring season progressed, some fry passed through the net and not into the live car where they could be counted. The percentage lost is not known, but likely increased through the field season. The net catches must therefore be considered a minimum that passed that water column in the sampling period since some smolt avoided or escaped 12 the nets and some fry passed through the net web under some conditions. Other losses occurred when live cars occasionally flooded. Another limitation were the longer 9x9-foot net bridles coming from the higher cables over the river in 1983 as compared to 1982. The increased bridle lengths in 1983 increased net set and retrieval times and most likely reduced the accuracy of the 1-hour sets. These sets were in most cases 50- to 55-minute sets since the attempt was to set on consecutive hours from 9 p.m. to 3 or 4 a.m. This error in 1-hour sets was not corrected for because of the variability in the net haul times between stations. In calling a 50- to 55-minute set with additional varied set retrieve times (when the net is still fishing to some degree) a 1-hour set, we have slightly underestimated the numbers of fish actually passing the station in that 1 hour. This time error was less of a problem in 30- and 15-minute sets where there was sufficient time in consecutive hours to operate the net. However, even in these cases, the net can be fishing although inefficiently in both the set and retrieval process. In these shorter sets we can be overesti- mating the fish that passed that net station in the set time (15 or 30 minutes). With a mixture of "1-hour" and 15- or 30-minute sets, the underestimates and overestimates may to some degree offset one another. Varying river debris loads during the sampling period also influ- enced net and trap efficiencies to an unknown degree through the spring program in 1983. 13 3.6 FISH DIVERSION AND IMPINGEMENT SURVIVAL STUDIES Since the Newhalen River maintains a large run of sockeye salmon, concern has been expressed over the potential losses of outmigrants (fry and smolts) as a result of Passage through the project. Consequently, preliminary evaluations of project feasibility have considered means to intercept fry and smolts entering the canal and safely returning them to the river. A combined fish diversion and collection system has been suggested, using angled, traveling water screens. In order to obtain preliminary information on the potential effectiveness of the fish protection system, a series of fish diversion and impingement survival studies was conducted in June of 1983 on the Newhalen River at RM 13. The fish diversion and impingement survival studies were conducted in a 4x4x8-foot test flume. This flume was used for both diversion and impingement tests. For diversion testing, an insertable screen pane! was fabricated (Figure 4). The panel incorporated 2.0-mm plastic mesh as the diversion medium. The panel frame was designed to fit into the flume at a 25° angle to the approach flow with accurate alignment of the downstream end of the frame to a stationary bypass wal]. The bypass was six-inches wide, full depth and two-feet long and discharged directly to the river. At the upstream end of the flume, a 5.0-mm mesh inflow screen was placed across the flume entrance to contain test fish within the flume and to block the passage of larger debris. For impingement tests, the diversion panel and inflow screen were removed and a seqmented box was inserted across the width of the flume. The four segments were about one-foot wide and incorporated 0.5-, 0.5-, 1.0- and 2.0-mm plastic mesh, respectively (Figure 5). Testing was conducted with the 1.0-mm and 2.0-mm meshes only. A 5.0-mm plastic mesh was attached to the front of the entire box which contained the test fry within the appropriate segment. 14 zLocs6ow 2mm Angled Screen i : i Flow | UT : | e = y ana 3 i i 5mm Inflow Screen | Da i Sent NEWHALEN RIVER Angled Screen Flume Arrangement (Plan) Figure 4 LS clocs6ov i | | LL i 38 ni as, ik, \ Impingement Test Chamber Insert li Plan View of Flume with Impingement Test Chamber Inserted Figure 5 16 For all testing, the flume was submerged in the river near the shoreline to a depth of about |8-inches. Given available river flows at the selected location, a mean cross-sectional velocity of about 2.2 feet per second was achievable with the anqled screen in the flume (Figure 6). Locating the flume in a higher velocity area was not deemed desirable for these preliminary studies due to the difficulty in securing it firmly with available anchoring devices. The selected location also resulted in relatively uniform flow conditions, as shown on Figure 7. All test fish were supplied by Dames & Moore and were collected at the flume site with the 9x9-foot fyke nets (smolt) and the inclined plane trap (fry) described previously. Fish were generally tested within one day of capture. Prior to testing, they were held in tanks (smolt) or a netted box (fry) submerged in the river. Testing of the angled screens was conducted with both fry and smolt. Since smolt were capable of swimming easily against the maximum velocity achievable in the flume (approximately 1.1 feet per second), all tests were conducted at this velocity. Fry, on the other hand, displayed little ability to guide along the screen at this velocity and were, therefore, tested at approach velocities as low as 0.5 feet per second, Few smolt were available for angled screen testing. Further, the fish were obviously capable of maintaining their position in the flume at the velocities tested and easily avoided impingement on the screen. Therefore, for these preliminary studies, efforts were concentrated on observing behavior for input to future studies rather than gathering extensive quantitative data. Unlike smolt, fry appeared to have difficulty diverting on the screen at a low velocity. In general, more than 50 percent of the fry impinged immediately upon release while the others diverted to the bypass. Eventually, the impinged fish worked their way along the screen and bypassed, usually within several minutes. It appeared that the fry had the ability to orient into the current and swim against relatively high velocities. However, they did not react as strongly to the screen as might have been expected. Since fry impingement rates were high, and the need for a collection-type of screen was evident for this life stage, diversion testing again concentrated on observing behavior rather than collecting quantitative data. 17 -y Water Depth = 20” Flume Cross-Sectional Velocity (Feet Per Second) Distribution Upstream of Angled Screen 18 Figure 6 A0983014 : | | i | 4 A AAAAAAAAAADDAAAL Eee 2 7 | Ni . : NS i : CS Velocity Distribution Along Angled Screen at Approach Velocity of 0.6 Feet Per Second (Measurements Taken at Mid-—Depth) Figure 7 LO © Ry S a a i A0983015 As previously stated, impingement survival tests were conducted with |.0- and 2.0-mm meshes. Although little was known about the survival potential of sockeye fry, it was believed that they would be relatively hardy. Therefore, early tests were conducted for impingement durations of eight and 16 minutes. Since these durations initially resulted in low mortality, all further tests were conducted similarly. Every attempt was made to maintain the highest possible velocity through the test screen panels. However, velocities generally decreased slightly over the duration of the test due to debris clogging. Velocities at the beginning of each test ranged from 1.2 to 1.5 feet per second; by the completion of a test, the velocity had decreased by no more than 0.2 feet per second. At the time of each impingement test, two lots of about twenty fry were placed in a release container. The test screens were cleared of debris and a rubber mat was placed across the front of the two test chambers to stop the flow. The fish were then released into the 1.0- and 2.0-mm screen seqments and the rubber mat was immediately removed causing the fry to impinge across the surface of the two meshes. After the desired test duration, the mat was again placed across the test area to restrict the flow. Fry were observed immediately for signs of stress or injury and were then removed to a holding area for observation of latent (48 hours) survival. For each day's experiments, a control group of fry was held for comparison of 48 hour mortality with the test fish. The controls were treated in exactly the same manner as the test fish but were not subjected to impingment. The holding facility consisted of a flow-through water bath in which 4-inch diameter holding cups with mesh-covered bottoms were placed to hold test and control fry. Each group of about twenty test or control fish was split equally between two cups to avoid crowding. Initial mortality observations were made one hour after each test. This short delay allowed stunned fish to recover or die. Thereafter, mortality was recorded at 6, 12, 24 and 48 hours. After 48 hours, all remaining live fish were enumerated and returned to the river. 20 4.0 RESULTS AND DISCUSSION 4.1 SPRING STUDIES In the period from May 11 to June 22, 1983, Dames & Moore, assisted by FRI, completed over 1,150 observations of sockeye smolt and fry catches from the nets and trap fished at RM 13. In this period, over 23,000 smolt and over 100,000 fry were captured and enumerated. Fork length on several thousand of these smolt and fry was measured and recorded and over 200 smolt were processed for scales, length, and weight. Several hundred smolt and fry were labeled and preserved. All scale, smolt, and fry samples are available to ADF&G from FRI. In 1983, as in 1982 (Dames & Moore 1982), a great deal more analyses are possible with the available data set. Therefore, all pertinent data collected are appended to this report. Appendix Tables 1 and 2 present the raw data used in these analyses. As per the request of ADF&G, Appendix Table 3 provides the sockeye smolt length and weight data for the slide- mounted scales taken in 1983. Appendix Table 4 provides air and water temperature data for several Newhalen River locations. The 24-hour pyroheliometer strip charts for the period May 16 through June 18, 1983 could not be reproduced. The original charts are avaliable from FRI upon request. As in 1982 and shown on Figure 2, the Newhalen River again underwent dramatic flow increases in 1983. The cross-sectional velocity profiles at RM 13 for two flow levels are shown in Figure 8. All velocities were measured about 1 foot under the water's surface. Increasing day length and generally increasing air and water temperatures also occurred through the 7-week spring period. 4.1.1 Spacial Distribution Smolt: While no specific study was directed at smolt vertical distribution, a dramatic difference between 1983 and 1982 was seen in smolt occurrence in the upper 18 inches at the river's surface.

In 1983, at RM 13, almost no smolt were taken with the IPT. Many factors could contribute to this vertical distribution change including the different sampling site, dominance of 1+ smolt in 1982 and 2+ smolt in 1983, density of smolt, etc. Of interest are the unconfirmed reports from the Kvichak River acoustic site that smolt were deeper in the water column in 1983 than in prior years. The horizontal distribution of smolt at RM 13 was much less distinct than at RM 7 in 1982. This is possibly due to age and abundance of smolt as well as the less distinct channel and the pattern of river water velocities at RM 13 in 1983 (see Figure 8). This may also be due to a better definition of smolt distribution in 1983 as compared to 1982. As part of the smolt outmigration enumeration (Section 4.1.3), the following relationship between stations was summarized for the entire spring period: Station: West Bank 1 Z; 3 4 5) 6 East Bank Smolt 0 QO 0.106 0.564 1.0 0.324 0 0 relationship to index Inconsequential numbers of smolt were taken on and near shore. Thus, no percentage amount of smolt were assigned there. At RM 7 in 1982 with many more 1+ than 2+ smolt (reversed in 1983) and under different site and velocity conditions, almost 90 percent of the smolt were estimated to have passed through the horizontal area represented by a sinale midriver station (Number 2). Fry: The vertical distribution of fry was seen by comparing IPT and 9x9-foot net catches. As in 1982 the fry appear more numerous in the upper 18 inches of water fished by the IPT with the disproportionate catch to area sampled. A 9x9-foot net, fishing an average of six feet deep, samples about 7,776 square inches of water while the 18x30-inch IPT opening samples about 540 square inches of surface water or about seven percent of the 23 9x9-foot net. The IPT captured almost 33 percent of the fry taken throughout the sampling period. Since the 9x9-foot nets likely lost fry through the mesh under some water velocity conditions, the IPT may in fact have taken closer to 40 percent of the fry with less than 10 percent of the sampling area of the 9x9-foot net in six feet of water. More sophisticated net or trap designs would be required to further define the vertical distribution of fry. Fry definitely favored the near-surface area in 1982 and 1983. The horizontal distribution of fry at RM 13 was like the smolt there in 1983 in being somewhat more spread out across the river when compared with 1982 fry at RM 7. The different site conditions and reduced fry densities in 1983 may contribute to this difference. As part of the fry outmigration enumeration (Section 4.1.3), the fry catch data from nets and trap were compared to arrive at a relationship of shore and all river stations to the index station so that an estimate of the fry outmigration could be made. The following relationship between shore and stations was summarized for the entire spring period: Station: West Bank 1 2 3 4 5 6 East Bank Fry 0 0.020 0.147 0.222 1.0 1.233 0.050 0.33 relationship to index The reasons fry were somewhat more horizontally spread in 1983 (RM 13) as compared to 1982 (RM 7) are not clear. Fry density was reduced in 1983 compared to 1982. Site conditions, including closer proximity to different sources of fry, may be a factor. Also, the 1983 sampling program at RM 13 sampled six fewer miles of mainstem produced fry. As with smolt, the more refined sampling effort in 1983 may have provided more details of fry distribution than were possible in 1982. 4.1.2 Temporal Distribution Smolt: The temporal pattern of sockeye smolt seen in the sprina of 1983 is shown on Figure 9.

In 1983 (Figure 9) the third net catch at the index station (Station 4) was the largest achieved. With this pattern of occurrence by catches at Station 4, it appears that smolt had started their movement from the Newhalen River system about the same time as in 1982. If the large peak in 1983 was the maximum smolt appearance, this is quite close to the same date that smolt peaked more gradually in 1982. Earlier net catches with 3x9-foot nets (May 16 to 20) did not capture large numbers of smolt, possibly indicating the May 23-26 and June 1-2 peaks in Figure 9 were irregular occurrences rather than the end of a multi-day peak in smolt movement. Unfortunately, our goal in 1983 of starting sooner was not met. Hopefully an earlier field season can occur in a future year. Another smolt difference is the multi-day pattern of smolt occurrence in 1982 versus the more sporadic appearance of smolt in 1983. This may be due to the smolt abundance/age differences, the closer proximity to different sources of smolt in 1983, and the different site characteristics between RM 7 and 13. The disturbing situation in this smolt temporal distribution is that smolt in large numbers could have been moving prior to the initiation of sampling. If this is the case, smolt escapement estimates are likely conservative with fish missed before RM 13 sampling was operational. Fry: The temporal distribution of sockeye fry in 1983 (Figure 10) was much like that in 1982. Fry peaked at about the same time in each year--June 7 to 12. The fry catch curve in 1983 (Figureiy) did not seem as closely timed to river flows as in 1982 although there still appears to be an association. Fry movements in the Newhalen River may be more associated with day lengths than previously thought on the basis of the 1982 (RM 7) study. A different type of water year with river flows out of the 1982 or 1983 pattern would be required to determine whether flows or day length are dominant factors in fry movement. 26 Number of Fry Job No.12023-0 13-20 Mean River Flow 27 River Flow (cfs x 1000) Daily Inclined Plane Trap Fry Catches, Newhalen River (RM 13), 1983 Dames & Moore Figure 10 4.1.3 Enumeration Smolt: The estimated number of sockeye smolt passing RM 13 from May 20 to June 19 in 1983 was 330,000, based upon a catch of over 17,000 smolt at the index station. Additional smolt were captured at other stations and a few smolt were taken in the IPT and shore nets. The one night's set with the 9x9-foot net on May 24/25 captured 70 percent of the smolt taken in the entire 1982 program with 4x8- and 3x9-foot nets at RM 7. The sampling program was better designed to achieve an outmigration estimate in 1983 and had more efficient nets than 1982. This 1983 smolt value is conservative since smolt were moving before and after this index period. The 1982 esti- mates may have been underestimated because of the single net sampling program and the smaller net openings. In reaching these extrapolated catches from the index areas a large potential source of error in this enumeration was seen. An inconsistent relationship was seen between the index station (originally at Station 4) and the other stations, especially 2, 3, and 5. The 1983 smolt were nearly all 2+ fish whereas most smolt in 1982 were smaller 1+ fish. Smolt were more horizontally spread in 1983 at RM 13 than at RM 7 in 1982 (see Section 4.1.1). Possibly some of these factors explain the inconsistent relationship of the index station to the other stations. Closer proximity to the sources of smolt at RM 13 in 1983 than at RM 7 might also be a factor in how hori- zontally distributed smolt are at the two sample sites. Another enumeration problem occurred on June 5 when a tree gave way on the downstream cable with the index station. When reset that day, the index station moved about 30 feet to the west to become about Station 3.5. To an unknown degree, the consistency of the "index" station was influenced. The better data set with 2 nets concurrently sampling in 1983 likely shows some details of the smolt distribution pattern that were not seen in the simpler data set in 1982 at RM 7. 28 Too many variables exist to directly compare the 1982 and 1983 smolt numbers at the RM 13 and RM 7 sites. Due to the greater sampling efficiencies in 1983, the 1983 smolt estimates are likely closer to true outmigration escapements than the 1982 estimates from RM 7. The 1983 smolt outmigration estimate is still conservative since smolt ran before and after the index period. However, the errors existent in apportioning the smolt numbers across the river in relation to a nonfixed index station could contribute to over or underestimates. Fry: The estimated number of fry passing RM 13 from May 16 to June 21 in 1983 was 1.3 million based upon the catch of over 47,000 fry in the index station net. More than 30,000 other fry were taken in the IPT and many thousand more fry were enumerated in the other net station sets as well as in the shore nets. The estimated passage at RM 13 ranged from under 1,000 to over 130,000 fry per day in this index period. The bulk of the fry at RM 13 passed by in 12 to 14 days. The fact that most of a distributional curve was seen indicates that no large numbers of fry were likely missed before sampling began and after the sampling was completed. As in the case of smolt, many variables exist that confound a comparison of 1982 and 1983 fry outmigration estimates. The estimated adult escapement to the Newhalen River system in 1981 and 1982 were about 250,000 and 215,000 respectively. However, some 64,000 of the 215,000 adults spawned in the mainstem Newhalen River in 1982 as compared to 10,100 in 1981. The majority of the production in the mainstem spawning area is above both RM 7 and RM 13. The 1981 adult escapement produced an estimated outmigration of 7 million fry, whereas the 1982 adult escapement produced an estimated outmigration of 1.3 million fry. This discrepancy of a disproportionate fry outmigration from similar numbers of spawners has several possible explanations. First, the 1982 fry outmigration may have been overestimated while that of 1983 may have been underestimated. Secondly, the fry surival may have been considerably less from the 1982 spawning than that of 1981. However, other Factors may be involved. Six more miles of mainstem spawning went past RM 7 that were not seen at RM 13. This is not believed to be a major source of error with the observed distribution of adults seen by FRI. Information on 29 the origins of fry in the 1982 and 1983 outmigrations is incomplete. Condi- tions in the nursery areas of juvenile sockeye salmon in Lake Clark, Six-Mile and Alexcy Lakes, may have been different enough to influence the duration of residence before outmigration to Iliamna Lake. Therefore, it is possible that a smaller portion of the production from the 1982 spawning, as compared to that of 1981, migrated out of the Newhalen River system as fry and may migrate later as age 1+ and 2+ smolts in 1984 and 1985. The extrapolations made for the lost IPT in 1982 (Dames & Moore 1982) could have caused over- or underestimates of the fry outmigration. The 1983 nets likely lost an increasing number of fry as the season (and associated water velocities) progressed, causing an underestimate in 1983. This does not appear to be a major factor since IPT and index net catch ratios remained fairly constant through the 1983 sampling period. 4.1.4 Smolt Age-Lenath Relationships Some 184 of the 209 smelt scales samples taken in 1983 were evaluated for age at FRI. Figure 11 presents some representative scale photographs. As noted earlier, 2+ smolt dominated the 1983 samples making selection of 1+ sized smolt easier than in 1982 when 1+ smolt domineted. The selection of scales was mostly from intermediate sized smolt to locate a break point in age and length. Figure i2 presents the results of these evaluations. A relatively sharp break exists at 97 to 98 mm with one scale overlap. This is somewhat less than the 101- to 102-mm dividing point selected in 1982. Appendix Table 3 provides all of the length and weight data collected along with the slide numbers on which the scales are mounted. This scale collection is available to ADF&G from FRI if required in future studies. 4.1.5 Lenath-Freauency Evaluation All length-frequency information collected for fry and smolt is tabu- lated (Appendix Table 2). No effort to manipulate these data was attempted in 1983. As in 1982 (Dames & Moore 1982), most of the data are for smolt and not for fry. 30 OZ-E€10-E207t “ON Gor TE TI eanbiy _—~-89 19 LEGEND: 97,21 = Length in mm, scale slide number \ me Bt ye A \ , at 101,22 Selected Scales (x 34) of Newhalen River Sockeye Smolt, RM 13, 1983 1983 184 Newhalen River, + N - = = = = = Sockeye Smolt Age - Length Relationships, RM 13 Smolt length in mm eqep ON e7zep ON e1ep ON wo Oo 4 a zLOws 40 uaquiny Dames & Moore Job No. 12023-013-20 32 Figure 12 Fry: As in 1982, the small numbers of fry measured indicated no real growth pattern over the period May 16 to June 22 when they were measured. Of interest and related to fry length was the fact that "unbuttoned" fry were seen both in early and late spring sampling, possibly indicating the close proximity of a fry source(s) to RM 13. Smolt: Computer time, as well as other analytical time, was not budgeted in 1983 for length-frequency evaluations. Evaluations were made in 1982. The striking contrast between 1982 and 1983 is the change in dominance of age classes. In 1982, 1+ smolt from the large 1980 adult escapement of 1.5 million dominated all smolt catches. In 1983, the same adult escapement produced a group of 2+ smolt that dominated the spring period outmigration of smolt. 4.1.6 Other Fish Observations As indicated in the catch tables by gear type (Appendix Table 1), few other fish species were taken at RM 13, much as at RM 7 in 1982. Cottids again dominated the other fish taken. Small Arctic char also were present along with incidental catches of sucker, cisco, sticklebacks, whitefish, and one burbot. Visual and hook-and-line efforts indicated larger resident fish were present at RM 13 as sampling began. In 1982, few resident fish were seen until early June (Dames & Moore 1982). A sizeable population of Arctic char and grayling developed behind holding pens and our fish count-and- release area. A few rainbow trout were also located there. A single lake trout was also captured there by hook-and-line. 4.1.7 Final Comments The cabled net: sampling system used in 1983 at RM 13 had one major drawback which was fish mortality. When the nets were new and velocities 33 were lower in the early spring season, few mortalities were noted if set times were held to 15 or 30 minutes when large numbers of fry or smolt were expected. Later in the season as the cod end of the 9x9-foot nets sagged and as water velocities increased, more mortalities of juvenile fish, especially fry, were noted. Mortalities were corrected as far as possible with reduced net fishing times. We did not feel that sampling for less than 15 minutes was practical considering that some fishing time occurs both when the net is being set and retrieved. The IPT on the other hand had few mortalities except when a "catching bag" was placed in the IPT live box. This netting restricted fry movement and in higher velocity periods combined to cause some mortalities. The net was no longer used once this situation was recognized as a problem. Any future work should look to reducing fry and smolt mortality either through reduced handling--more acoustic attempts and/or other gear types such as larger IPTs fishing deeper which divert fish to a live car rather than funnel them down a net into a hose and into a live car. 4.2 SUMMER STUDIES As RM 13 was demobilized in late June 1983, the RM 22 adult counting camp was mobilized. FRI completed all juvenile and adult sampling at this site, which operated from June 28 to August 13, 1983. 4.2.1 Juvenile Observations The IPT, moved up to RM 22 from RM 13, only caught ten sockeye fry and two sculpins. The reasons for the low 1983 catches are not clear. The IPT was placed in a deeper channel area nearer to the east bank of the river. With the poor success of the IPT at smolt capture in 1983 at RM 13, it is not surprising that no smolt or yearlings were taken. While fry continued to move past RM 22 in small numbers in the summer and fall of 1982, either no fry moved in the summer of 1983 or the IPT did not capture them. No conc- lusions can be drawn except that few fish were taken in 1983. 34 4.2.2 Adult Observations Table | presents the daily adult sockeye escapement evaluation for RM 22 in 1983. The total estimated escapement in 1983 was 702,792 adult sockeye salmon. Some Iqiugig-tagged adults were also observed at RM 22. The results of this taqgina study will be available from the University of Alaska, Juneau, after the study ends and analyses are completed. 4.3_ FISH DIVERSION AND IMPINGEMENT SURVIVAL STUDIES Results of diversion tests with smolt (100-120 mm) clearly indicated that these fish are capable of easily swimming against the velocities tested. Upon release into the flow, the smolt distributed across the flume; some diverted within several minutes to the bypass while others remained in the flume for up to several hours. Diversion tests with fry (28-32 mm) indicate that this life stage does not respond strongly to an angled screen. At a velocity of 1.0 foot per second, most of the fry impinged on the screen upon release but qradually worked their way to the bypass. Impingement was relatively random in terms of fry orientation (i.e., head first, tail first, up-side down, etc.) indicating that the fish were generally overcome by the current without being able to orient into it. Similar results were noted with fry at 0.9, 0.7, 0.6 and 0.5 feet per second velocities. However, as the velocity decreased, more fish were able to divert to the bypass without impingement. Nonetheless, even at 0.5 feet per second, some impingement was noted. Results of fry impingement tests are summarized in Table 2. Mean survival at the mesh size/impingement duration combinations tested ranged from 87.3 percent to 95.8 percent. Contingency table analyses indicated no significant differences in survival between the four test conditions. Therefore, the data can be combined to yield an overall mean survival value of 93.1 percent. Since the mean control survival was 93.4 percent, the differential mortality between test and control fish was essentially zero. Therefore, under the conditions tested, it can be expected that sockeye salmon survival would approach |00 percent in a screening system involving impingement and removal to a return location in the river. 35 TABLE 1 NEWHALEN RIVER (RM 22) ADULT SOCKEYE ESCAPEMENT, 1983 Date Daily Cumulative Date Daily Cumulative June 28 0 0 July 21 17,274 452,454 29 6 6 22 9,870 462,324 30 0 6 23 11,874 474,198 July 1 0 6 24 10,920 485,118 2: 18 24 25 8,232 493,350 3 9,858 9,882 26 15,090 508,440 4 18,210 28,092 27 14,400 522,840 5 34,854 62,946 28 18,840 541,680 6 40,014 102,960 29 23,826 565,506 7 41,376 144,336 30 25,518 591,024 8 29,844 174,180 31 19,188 610,212 2 18,624 192,804 August 1 14, 334 624,546 10 14,670 207,474 2 13,422 637,968 11 16,104 223,578 3 15,504 653,472 12 30,246 253,824 4 13,692 667,164 13 26,472 280,296 > 13;,212 680, 376 14 44,850 325,146 6 6,432 686, 808 15 27,852 352,998 7 9,578 696, 186 16 19,836 372,834 8 684 696,870 17 23,724 396,558 9 1,176 698 , 046 18 10,320 406, 878 10 1,452 699,498 19 10,608 417,486 a 1,206 700,704 20 17,694 435,180 12 M5592) 702,096 13 696 702,792 SSeS 36 A) B) C) D) E) TABLE 2 SUMMARY OF FRY IMPINGEMENT DURATION TEST RESULTS Mean Survival at Each Test Condition Impingement Duration Mesh Size 8-Min. 16-Min, 1.0-mm 9444 -8725 (n=6) (n=5) 2.0-mm -9583 -9505 (n=5) (n=4) Mean Overall Test Survival = .9313 Mean Survival for Each Duration and Mesh Size Duration: 8-min. = .9558 16-min. = .9071 Mesh Size: l-mm_ = .9064 2-mm_ = .9627 Mean Control Survival = .9342 Mean Differential Mortality Differential Mortality = Test Mortality - Control Mortality = (1 - .9313) - (1 - .9342) = .0687 - .0658 = .0029 or 0 37 5 «1 5.0 CONCLUSIONS SPRING STUDIES 1. A 7-week field effort in 1983 involving net and trap sampling of juvenile sockeye salmon was completed at RM 13 on the Newhalen River, Alaska as part of an ongoing hydropower feasibility study. Sampling was completed on a very dynamic river system with changing climatic and light conditions. In the period from May 11 to June 22, some 1,150 observations of sockeye smolt and fry catches from nets and an inclined plane trap (IPT) enumerated over 23,000 smolt and over 100,000 fry. Some smolt and fry catches were subsampled for length, weight, and scales. While fry and smolt favored the mid-river area at RM 13, there was not the distinct "fast lane" observed in 1982 at RM 7. The reasons for this are not clear but different site conditions are likely a major factor. Vertical patterns of fry in 1983 appeared similar to 1982. Fry favor the water column near the surface. Smolt, on the other hand, appeared to run deeper at RM 13 (1983) than at RM 7 (1982). Possible causes include different site conditions and the dominance of 2+ smolt in 1983. In 1982, 1+ smolt dominated. Other factors may be involved including closer proximity at RM 13 to smolt sources (Six-Mile Lake and Lake Clark) than existed at RM 7. The temporal distribution of smolt in 1983 appeared to peak in a very sporadic way about May 23 to 26 or about the same time as in 1982. The temporal distribution of smolt in 1983 indicates the large nets began operation near the middle of the overall 38 10. v1 smolt outmigration. However, other smaller nets did not catch large numbers of smolt between May 16 and 21. Smolt were present as sampling started and ended. The temporal distribution of fry in 1983 appeared similar to that of fry in 1982. Fry peaked about June 7 to 10 in 1982. The peak was about June 9 to 15 in 1983. As in 1982, the 1983 fry appeared cued to increasing river flows. Fry were present as sampling started and ended. The estimated number of smolt passing RM 13 from May 20 to June 19 in 1983 was 330,000. A confidence interval was not calculated but may approach 50 percent due to the inconsistent relationships seen between the index station and other stations at RM 13. The esti- mated number of fry passing RM 13 from May 16 to June 21 in 1982 was 1.3 million. A confidence interval was not calculated. The better data set in 1983 should place the interval below 50 percent. Some 184 of the 209 smolt scales taken in 1983 were aged and, with the exception of one scale, a length separation point of 97 to 98 mm could be selected between 1+ and 2+ smolt. Length-frequency data for fry in 1983 indicate little growth through the spring season as seen in 1982. Smolt data indicate that 2+ smolt almost completely dominated catches in 1983. In 1982, 1+ smolt were more numerous than 2+ smolt. The large 1980 adult escapement to the Newhalen River system explains this change in smolt age in 1982 and 1983. Cottids, as in 1982, dominated the catch of other fish species in 1983 at RM 13. Arctic char, sucker, cisco, rainbow trout, stickleback, and whitefish were also taken. One burbot and one lake trout were also captured at RM 13. 39 12. The large cabled nets, while more efficient on fry and smolt, unfortunately caused mortality problems for the fish, especially as the spring season progressed. Sampling times were shortened to reduce this problem. 5.2 SUMMER STUDIES 1. Few juvenile sockeye salmon were taken in an IPT at RM 22 in the period June 28 to August 13, 1983. No explanation exists for this observation. 2. Adult sockeye counts from June 28 to August 13 totaled 702,792 fish, well above 1981 and 1982, and below the 1980 escapements to the Newhalen River system. 5.3 FISH DIVERSION AND IMPINGEMENT SURVIVAL STUDIES 1. Sockeye salmon smolts appear to have the capability for complete diversion in an angled screen system at low velocities ( 1.1 feet per second). 2. Further studies are needed to quantify smolt diversion and survival at velocities higher than |.3 feet per second. 3. Sockeye fry are not capable of diverting along an angled screen, even at low velocities; therefore, in order to protect the fry, a collection system would be required. 4. Sockeye fry are capable of withstanding impingement on a fine mesh screen (1.0- and 2.0-mm) with very high survival at relatively low velocities (1.0 fps or less). 5. Higher approach velocities in the power canal would reduce costs; smolt appear to have the potential for diverting at high velocity; similarly, it would appear that fry could survive impingement at substantially higher velocities; therefore, further investigations of the angled screen diversion/collection system should concentrate on diversion and impingement survival at higher velocities than those used for this study. 40 Because of the favorable results obtained from the 1983 fish diversion and impingement studies, the next logical step in determining the feasibility of the Newhalen River Hydroelectric Project would be to conduct a fish diversion demonstration program on the Newhalen River. This program would employ facilities constructed at the edge of the river that would permit quantitive experiments over a longer period of time, concentrating on those parameters that appear to be most critical for fish protection. Such a program would produce necessary data for engineering design of the intake canal. The program would also provide a visual demonstration to Bristol Bay residents and interested fisheries agencies regarding the effectiveness of a diversion system for protection of downstream juvenile sockeye salmon migrants. 41 6.0 REFERENCES Dames & Moore, 1982.
