In 2008, the Portland District of the U.S. Army Corps of Engineers (USACE) contracted with the Pacific Northwest National Laboratory (PNNL) to conduct an acoustic telemetry study to estimate the survival rates of juvenile Chinook salmon and steelhead passing through Bonneville Dam (BON) and its spillway. Of particular interest was the relative survival rate of smolts detected passing through end spill bays 1-3 and 16-18, which had deep flow deflectors immediately downstream of spill gates, versus the survival rate of smolts passing through middle spill bays 4-15, which had shallow flow deflectors.Yearling Chinook salmon (YC), steelhead (STH), and fall Chinook salmon (FC) longer than 95 mm were collected from routine smolt monitoring samples at John Day Dam (JDA) and held overnight before surgery so that they were not overly stressed. Smolts longer than 95 mm were surgically implanted with Juvenile Acoustic Telemetry System (JSATS) and passive integrated transponder (PIT) tags and held another night to allow time for fish to recover from surgery. Fish tagged the previous day were released by a PNNL team three times per day (morning, midday, and night) in the JDA pool near Arlington, Oregon, and about 2.5 km below JDA in spring and summer. The team also released FC about 3 km below The Dalles Dam (TDA) in summer. Releases of live JSATS-tagged smolts in the Columbia River upstream of BON totaled 3431 YC and 3430 STH in spring. In summer, 5909 FC were released upstream of BON. Releases were spread out over 28 consecutive days (April 29 through May 27) during spring and over 29 consecutive days (June 15 through July 13) in summer. All of the "treatment" fish released above BON had the opportunity to be detected and regrouped by a BON forebay entrance array of autonomous nodes or by dam-face arrays at the BON spillway (this study) or BON Powerhouse 2 (B2) ) before they passed the BON project. An array is a group of underwater listening devices deployed to detect acoustic tags in fish passing through a forebay or an entire cross section of the river above or below a dam. Non-spillway passage routes were assigned based on detections of PIT tags in the B2 Corner Collector (B2CC) and B2 Juvenile Bypass System (B2 JBS) and acoustic detections on a cabled JSATS array in the B2 forebay (from Faber et al. 2009). Routes of spillway passage included end bays 1-3 and 16-18 with deep flow deflectors downstream of spill gates and middle bays 4-15 with shallow flow deflectors. Powerhouse 1 was not monitored.A National Marine Fisheries Service (NMFS) team released 826 live and 50 dead tagged YC in spring and 1020 live and 52 dead tagged FC smolts in summer into the downstream end of the BON tailrace near the USACE boat launch three times per day (about 0600, 1300, and 2100 hours PST) to serve as reference releases (controls) for virtual releases of treatment fish from upstream of the dam. Reference releases were made daily from April 30 through June 2 and from June 16 through July 22. The NMFS team also released 826 live YC and 1020...

Executive SummaryIn 2008, the Portland District of the U.S. Army Corps of Engineers contracted with the Pacific Northwest National Laboratory (PNNL) to conduct an acoustic telemetry study to evaluate a newly deployed 700-ft-long and 10-ft-deep behavioral guidance structure (BGS) located in the forebay of the Bonneville Dam second powerhouse (B2) and to estimate the survival of yearling Chinook salmon, subyearling Chinook salmon, and juvenile steelhead passing downstream through this powerhouse. The BGS was deployed to increase the survival of fish passing B2 by increasing the percentage of outmigrating smolts entering the B2 Corner Collector, a surface flow outlet known to be a relatively benign route for downstream passage at this dam. Fish longer than 95 mm were surgically implanted with Juvenile Salmon Acoustic Telemetry System (JSATS) and passive integrated transponder (PIT) tags, held overnight in tanks supplied with continuous flow of river water to allow time for recovery from surgery and released upstream as part of two concurrent survival studies that were evaluating survival at John Day Dam and the Bonneville spillway. Tagged fish were released at or downstream of Arlington, Oregon, approximately 156 km upstream on the Columbia River. Additional release points included the tailwaters of John Day Dam and The Dalles Dam. The volitional movements of the tagged migrants were subsequently tracked through the B2 forebay to their eventual route of passage. Passage location was recorded and incorporated with detections from three downstream survival arrays to produce survival estimates. The tracked positions of fish in the forebay and passage distribution at B2 were evaluated to determine behavior relative to the BGS location. Major FindingsThe BGS increased passage percentage into the B2 Corner Collector (B2CC) for yearling Chinook salmon by up to 9%, but no improvements were observed for subyearling Chinook or juvenile steelhead when comparing 2008 results to passage distributions observed in 2004 and 2005 radio-telemetry studies. The majority of steelhead and yearling Chinook salmon were found to navigate past the BGS and through the south gap (area between the downstream tip of the BGS and Cascade Island), which was closest to the Corner Collector. Whereas equal proportions of subyearling Chinook salmon navigated through the south and north gaps between the BGS and shorelines. The corner collector efficiency was always higher for fish passing through the south gap compared to fish passing the north gap or under the BGS. Overall, the B2 corner collector efficiency was very high for juvenile steelhead (75%) followed by yearling Chinook salmon (49%) and then subyearling Chinook salmon (40%). Downstream migrants appeared to navigate downstream proportionally to water velocities in the thalweg when their downstream pathways were plotted in relation to the BGS and the B2 forebay. There were significant operational differences at B2 between spring and summer. During spring, turbine unit 15 (in the center of the p...

“…Overall during this period, 31.6% of total discharge was spilled, including 9.5% TSW discharge. During the first half of the spring portion of the study, tagged fish were released when discharge was at or below the 10-year average (1998to 2007Figure 3.1). Discharge was higher than the 10-year average during the second half of the spring season.…”

Executive SummaryImproving survival rates of juvenile salmonids through the Federal Columbia River Power System (FCRPS) continues to be a high priority for the U.S. Army Corps of Engineers, Portland District. Many of these fish are from populations listed as threatened or endangered under the Endangered Species Act of 1973. Increased survival rates are necessary to meet performance standards set forth in the 2008 Biological Opinion (BiOp) on FCRPS operations. The BiOp mandates 96% and 93% survival rates be achieved for spring and summer downstream migrating juvenile salmonids, respectively. At John Day Dam, the Portland District is evaluating the provision of surface flow outlets (SFOs) as a means to increase fish-passage efficiency and in turn increase passage survival rates by reducing turbine passage of juvenile salmonids. The goal of the study reported herein is to provide the passage and survival data necessary to evaluate the performance of the prototype SFO and the dam as a whole relative to the standards in the BiOp. The study was conducted by the Pacific Northwest National Laboratory and the University of Washington. The Portland District and regional fisheries managers will use the data to adaptively manage the configuration and operation of John Day Dam to maximize the survival rates of juvenile salmonids. ObjectivesIn this report, we present survival estimates, passage efficiencies, and fish behavior data for acoustictagged steelhead (STH), yearling Chinook salmon (YC), and subyearling Chinook salmon (SYC) passing through John Day Dam during 2008. We examined the data relative to two spill treatments, 30% versus 40% spill out of total water discharge through the dam, to assess the performance of SFOs, called topspill weirs (TSWs). The field study period was from April 29 to August 20, 2008. The objectives were as follows:• Survival Rates -Estimate single-and paired-release, route-specific, dam-passage, and concrete-passage survival rates for YC, STH, and SYC passing through John Day Dam for each of two spillway operational treatments.• Fish Passage -Estimate passage proportions among major passage routes, and calculate efficiency and effectiveness metrics for each of two spillway operational treatments for YC, STH, and SYC separately.-Estimate travel times (forebay residence and tailrace egress) of YC, STH, and SYC for each of two spill treatments.• Fish Behavior -Characterize fish behaviors, including forebay approach paths, for YC, STH, and SYC and compare approach paths with the final route of passage for each of two spill treatments.-Describe vertical and horizontal distributions and residence times of YC, STH, and SYC within the dam forebay. MethodsThis study used the Juvenile Salmon Acoustic Telemetry System (JSATS). We surgically implanted acoustic tags and passive integrated transponder tags in 3447 YC and 3450 STH in spring and in 5931 SYC in summer. Median lengths of tagged fish were as follows: YC = 158 mm; STH = 217 mm; SYC = 117 mm.Tagged YC and STH were released daily over a 29-day spr...
