The Columbia River Research Laboratory
The mission of the Columbia River Research Laboratory is to serve the public by providing scientific information to support the stewardship of our Nation's fish and aquatic resources, with emphasis on the Columbia River basin. As a part of the U.S. Geological Survey (USGS) Western Fisheries Research Center, we conduct objective, relevant research and seek partnerships to help fulfill this mission.

Survival and migration behavior of juvenile salmonids at McNary Dam, 2006
During 2006, we used acoustic telemetry and a route-specific survival model (RSSM, Skalski et al. 2002) to estimate behavior, passage, and survival of juvenile salmonids during two different spill operations and diel periods at McNary Dam. An evaluation of 12-h versus 24-h spill was proposed for the spring migration period at McNary Dam. However, high river discharge did not allow for the 12-h spi
Bypass system modification at Bonneville Dam on the Columbia River improved the survival of juvenile salmon
From 1987 to 1992, we evaluated a fish bypass system at Bonneville Dam Powerhouse 2 on the Columbia River. The survival of subyearling Chinook salmon Oncorhynchus tshawytscha released into the system ranged from 0.774 to 0.911 and was significantly lower than the survival of test fish released into turbines and the area immediately below the powerhouse where bypass system flow reentered the river.

Distribution, migration behavior, habitat use, and species interactions of fall-released juvenile hatchery spring Chinook salmon in the Deschutes River, Oregon, 2003
In a review of National Fish Hatcheries (NFH), the U.S. Fish and Wildlife Service (USFWS) identified the need to assess the fate of hatchery-reared fish and their potential effect on the aquatic community (USFWS 1998). Additionally, the National Marine Fisheries Service (NMFS) recommended monitoring and evaluating ecological interactions between hatchery and wild fish (NMFS 1999; Columbia River Bi

Passage behavior of radio-tagged subyearling Chinook salmon at Bonneville Dam, 2004
Flow augmentation, spill, surface collection, and improved turbine guidance systems have been identified as potential management actions to improve passage efficiency and survival of outmigrating juvenile salmonids. The U.S. Army Corps of Engineers (USACE), along with regional, state, and federal resource agencies, has designed and implemented studies to determine which management actions would pr
