    We analyzed 6 years () of passage and survival data collected at McNary Dam to examine how spill bay operations affect survival of juvenile salmonids passing through the spillway at McNary Dam. We also examined the relations between spill bay operations and survival through the juvenile fish bypass in an attempt to determine if survival through the . Hydroacoustic Evaluation of Juvenile Salmonid Passage at The Dalles Dam Spillway, iii Preface This research was conducted under the auspices of the U.S. Army Corps of Engineers, Northwestern Division’s Anadromous Fish Evaluation Program (AFEP) to implement the Congressionally-appropriated Columbia River Fish Mitigation Project.

These tagged fish were released to support passage survival studies at John Day Dam, The Dalles Dam, and Bonneville Dam in The Juvenile Salmon.

About 80 percent of juvenile fish pass over The Dalles Dam’s spillway. The new.

3 Inour study objective was to estimate the relative survival of juvenile coho salmon (O. kisutch) and subyearling fall chinook salmon (O. tshawytscha) passing through The Dalles Dam spillway under 64% spill conditions. Dam to evaluate the relative survival of juvenile Pacific salmon (Oncorhynchus spp.) through the spillway when 64% of river flow was spilled.

Equal numbers of fish were released during the day and night. Fish were tagged with passive integrated transponder (PIT) tags at Bonneville Dam and transported to The Dalles Dam about 24 hours prior to release.

InNOAA Fisheries estimated relative survival for radio-tagged, river-run, hatchery yearling chinook salmon passing through the spillway at Lower Monumental Dam on the Snake River.

Review of Studies of Fish Survival in Spill at The Dalles Dam Assignment The Independent Scientific Advisory Board (ISAB) was asked in a memo dated Novem from Brian J. Brown, Chair, Implementation Team (IT), addressed to Michael Schiewe and Chip McConnaha, to review the issue of appropriate spill levels at The Dalles Dam.

Evidence of Delayed Mortality on Juvenile Pacific Salmon Passing through Turbines at Columbia River Dams Article (PDF Available) in Transactions of the American Fisheries Society (1)   Multiple dam passage during seaward migration is thought to reduce the subsequent survival of Snake River Chinook salmon.

This hypothesis developed because juvenile Chinook salmon from the Snake River, the Columbia River’s largest tributary, migrate > km through eight hydropower dams and have lower adult return rates than downstream populations that migrate through Cited by: Of particular interest was the relative survival rate of smolts detected passing through end spill bays andwhich had deep flow deflectors immediately downstream of spill gates, versus the survival rate of smolts passing through middle spill bays 4.

The survival of yearling Chinook salmon passing one, two, and three dams was %, % and %, respectively, while the survival of steelhead smolt passing one, two, and three dams was %, %, and %, by: 1.

Inthe National Marine Fisheries Service estimated relative survival for river-run hatchery yearling chinook salmon passing through two sections of the bypass system at Lower Monumental Dam on the Snake River. Fish were collected and marked with PIT tags at the Lower Monumental Dam smolt collection facility.

While the authors did not compare these numbers to survival through the turbines, they did have the perspicacity to suggest that "passage survival of juvenile salmonids at spill rates lower than 64% warrants further.

spilled, spill pattern, time of day, species/run, and dam configuration. Inthe primary way juvenile fish passed Bonneville Dam was through the turbines. At the time, fish researchers considered turbine passage safe; fish also could pass when spillway gates were opened, as they were from time to time to allow excess water to pass, and the dam included four small fish ladders especially for juvenile fish.

added for The Dalles and Bonneville Dams (NPPC ). The amendment also established a 90% survival goal for each project (except Bonneville Dam where the goal was 85%) and a goal of 85% fish passage efficiency (FPE), where 85% of the juvenile salmon were to pass through non-turbine routes.
