“…If the lower nighttime FGE were the norm, that would be yet another reason to avoid using end units with the lowest FGEs at night. At least the trend of higher nighttime passage of fish at B2 was consistent with what we observed in 2000 (Ploskey et al 2002b) and 2001 (Ploskey et al 2002c).…”

“…This has long been known to be typical of juvenile salmonid passage at northwestern dams. In general, surface passage routes, such as sluiceways and surface collectors, have higher passage during daylight hours whereas turbine units and deep-passage spillways have higher passage at night (Thorne and Johnson 1993;Johnson and Giorgi 1999;Johnson and Carlson 1998;Ploskey et al 2001aPloskey et al , 2001bPloskey et al 2002aPloskey et al , 2002bPloskey et al , and 2002c. In the 2001 drought season, we found a strong diel trend in spillway passage (with higher passage at night) even with very nearly constant spillway discharge (Ploskey et al 2002c).…”

“…The southern half of the spillway (spill bays 10 through 18) passed 13% and 14% more fish in spring and summer, respectively, than did the nine northern bays, largely due to low fish passage at bays 1 and 5. The southerly skew in passage distribution was even more apparent in spring and summer of 2000 (Ploskey et al 2002b) and spring 2001 (Ploskey et al 2002c) than it was in 2002.…”

Hydroacoustic Evaluation of Fish Passage through Bonneville Dam in 2004iii AbstractThe Portland District of the U.S. Army Corps of Engineers requested that the Pacific Northwest National Laboratory (PNNL) conduct fish-passage studies at Bonneville Dam in 2004. These studies support the Portland District's goal of maximizing fish-passage efficiency (FPE) and obtaining 95% survival for juvenile salmon passing Bonneville Dam. Major passage routes include 10 turbines and a sluiceway at Powerhouse 1 (B1), an 18-bay spillway, and eight turbines and a sluiceway at Powerhouse 2 (B2).In this report, we present results of four studies related to juvenile salmonid passage at Bonneville Dam. The studies were conducted between April 15 and July 15, 2004, encompassing most of the spring and summer migrations. Studies included evaluations of 1) project fish passage efficiency and other major passage metrics, 2) B2 fish guidance efficiency and gap loss, 3) smolt approach and fate at the B2 Corner Collector (B2CC), and 4) B2 vertical barrier screen head differential. Appendices A through I are presented on the accompanying compact disk (CD). Most are in an Adobe Acrobat portable document format (PDF) and six large tables in Appendix E (E3-E8) are presented only as comma-separated-variable files. The CD also includes a PDF version of the report.

“…The WES used fixed-location hydroacoustic methods to evaluate fish passage at the PSC (Ploskey et al 2000a) and overall passage at Bonneville Dam (Ploskey et al 2000b) in 2000. Their PSC study was divided into two sampling periods, spring (April 20 to June 1) and summer (June 5 to July 2).…”

This project was undertaken as part of the U.S. Army Corps of Engineers, Portland District's (CENWP) surface bypass program at Bonneville First Powerhouse (B1). Pacific Northwest National Laboratory (PNNL) performed the work under contract to CENWP (MIPR No. W66QKZ00200123 and 00125). BioAnalysts, Inc. subcontracted to PNNL (Contract No. 402827-A-B8). Besides synthesis of B1 surface bypass data, this project included tasks in FY2000 on coordination of biological/hydraulic data collection and a pre-study monitoring and evaluation plan. These tasks were accomplished separately from the data synthesis that is the subject of this report. The data synthesis occurred in two phases. The first phase, reported on December 8, 2000, focused on the PSC performance data, a subset of the total evaluation effort. The second phase, reported herein, includes all components of the 2000 PSC evaluation.

The Portland District of the U.S. Army Corps of Engineers requested that scientists with the Pacific Northwest National Laboratory (PNNL) and the U.S. Army Engineer Research and Development Center (ERDC) conduct fish-passage studies at Bonneville Dam using hydroacoustic evaluation methods. The ERDC also contracted with MEVATEC Corporation and Dyntel to provide staff ranging from scientists to technicians for the study. This study supports the Portland-District goal of maximizing fish passage efficiency (FPE) and obtaining 95% survival for juvenile salmon passing the Bonneville Project. This report presents results of two hydroacoustic studies of juvenile salmonids conducted in 2001 at Bonneville Dam in an extensive summary, in the main body of the report, and in appendices. Appendix E on the accompanying compact disk includes hourly estimates of forebay elevation and route-specific water discharge, fish passage, and associated variances and covariances. One study was a project-wide evaluation of fish-passage efficiency, and the other was a more narrowly focused study of the approach, vertical distribution, and fish-guidance efficiency (FGE) of fish at Unit 15, where the Portland District extensively modified the gatewell and vertical barrier screen to improve gatewell flow and FGE. The goal of the larger of the two studies was to provide project-wide estimates of FPE, spill efficiency, and spill effectiveness for run-of-river fish passing the Bonneville Project during the 2001 out-migration. This type of study also provides estimates of the horizontal, vertical, and diel distributions of fish passage and FGE by turbine unit. These data will provide a baseline for evaluating the performance of future management efforts to improve juvenile fish passage. The goal of the second study was to assess the effect of gatewell and vertical-barrier-screen modifications on the FGE of Unit 15.
