“…This could be a problem when virtual releases of veteran smolts are paired with reference releases of recently tagged smolts and the latter group suffered higher mortality than the former group. Faber et al (2009) found no evidence of post handling mortality of control fish when they compared paired-and triple-release survival estimates for YC smolts. Similarly, Faber et al (2009) found no significant difference between survival estimates for FC smolts from the paired-and triple-release models.…”

“…If the downstream controls experienced post-release handling mortality that had already been expressed in fish released upstream, dam-passage or spillway-passage survival estimates would be positively biased. This was the impetus for making specific releases of juvenile Chinook salmon smolts into the B2CC to provide a means of scaling paired-release estimates of dam-passage survival rates using a triple-release model, as presented by Faber et al (2009 …”

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...

Pacific Northwest National Laboratory (PNNL) and subcontractors conducted an acoustic-telemetry study of juvenile salmonid fish passage and survival at Bonneville Dam in 2010. The study was conducted to assess the readiness of the monitoring system for official compliance studies under the 2008 Biological Opinion and Fish Accords and to assess performance measures including route-specific fish passage proportions, travel times, and survival based upon a single-release model. This also was the last year of evaluation of effects of a behavioral guidance structure installed in the Powerhouse 2 forebay. The study relied on releases of live Juvenile Salmon Acoustic Telemetry System tagged smolts in the Columbia River and used acoustic telemetry to evaluate the approach, passage, and survival of passing juvenile salmon. This study supports the U.S. Army Corps of Engineers continual effort to improve conditions for juvenile anadromous fish passing through Columbia River dams.v PrefaceThe U.S. Army Corps of Engineers (USACE) Portland District, contracted with the Pacific Northwest National Laboratory (PNNL), in Richland, Washington, to conduct an acoustic-telemetry survival study at the Bonneville Dam in 2010. The PNNL assembled a study team consisting of staff from PNNL, the Pacific States Marine Fisheries Commission (PSMFC), and the University of Washington. The Portland District provided all funding and oversight.This final report presents behavioral and fish passage results for tagged yearling and subyearling Chinook salmon smolts and juvenile steelhead as part of a survival study conducted at Bonneville Dam during 2010.This report was originally published in December 2011. It was revised in August 2012 to address review comments from the Studies Review Work Group of the USACE's Anadromous Fish Evaluation Program. One important change was to revise the fish collection section to clearly present numbers and percents of fish rejected, excluded, tagged and released alive or dead, and to list the sum of extra fish that were collected but not needed to fulfill the daily tagging quota. The fish passage efficiency statitics were added to Tables ES-2 and ES-3. A paragraph describing comparisons of spill treatment and day and night effects in summer and Table 6.8 were added to Section 6.6. We also added tables of subyearling Chinook survival results for combinations of day, night, and spill level to the appendices. We did not accept the recommendation of one reviewer to limit reporting to single-release survival estimates and to avoid using passage survival through the Bonneville Powerhouse 2 Corner Collector as a virtual reference release to make surrogate estimates of paired-release survival. All capture histories and single-release survival results were the primary focus of this report and were tabled in the Executive Summary and appendices. Estimation of surrogate paired-release survival estimates was a reasonable and informative exercise that was retained for readers that might be interested, but those estimates...

Floating guidance structures are intended to promote safe passage for juvenile salmon migrating downstream through reservoirs. However, the ability of an engineered structure to guide fish to safe passage has been primarily tested through large-scale implementation in reservoirs or in laboratory studies and computer simulations without live fish. Research is needed that integrates fluid mechanics with fish behaviour to study how hydraulic conditions around a guidance structure trigger swimming behaviours. In this study, an outdoor experimental channel was used to identify: (a) the hydraulic signature of a floating guidance structure and (b) changes in fish swim behaviour in relation to channel hydraulics. The flow field surrounding a guidance structure at two deployment angles was characterized using acoustic Doppler velocimeters. Swimming behaviours of juvenile Chinook salmon were recorded using underwater videogrammetry. A statistical method for behaviour change detection identified the most likely locations of swimming behaviour changes in fish as they first encountered the guidance structure. Finally, the locations of behaviour changes were compared to the hydraulics surrounding each guidance structure. Taken together, results indicated the fish did respond to the guide wall with behaviour changes, but did not distinguish between the two guide wall angles. While the two guide wall angles did produce statistically different distributions of hydraulic variables, the differences were small, potentially too small for the fish to produce a behavioural response. To inform the design of guidance structures, further work may clarify if swim responses vary with more aggressive wall angles and/or higher approach velocities, or if any contraction of flow and/or visual cue will produce similar behaviour responses.

Of all passage routes at hydroelectric projects, turbines produce the highest rates of injury and mortality, which can be caused by high shear stress, turbulence, cavitation, decompression, blade strike, and mechanical wounding
