Summary of Survival Data from Juvenile Coho Salmon in the Klamath River, Northern California, 2007 Summary of Survival Data from Juvenile Coho Salmon in the Klamath River, Northern California, 2007
A study to estimate the effects of Iron Gate Dam discharge on ESA-listed juvenile coho salmon during their seaward migration to the ocean was begun in 2005. Estimates of survival through various reaches of river downstream from the dam were completed in 2006 and 2007 as part of this process. This report describes the estimates of survival during 2007, and is a complement to a similar...

Performance of a prototype surface collector for juvenile salmonids at Bonneville dam's first powerhouse on the Columbia River, Oregon Performance of a prototype surface collector for juvenile salmonids at Bonneville dam's first powerhouse on the Columbia River, Oregon
During April-July 2000, we radio-tagged and released juvenile Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) to evaluate a prototype surface flow bypass at Bonneville Dam on the Columbia River. The mock bypass, called a prototype surface collector (PSC), had six vertical slot entrances that were each 6 m wide and 12 m deep. The PSC was retrofitted to the...

Lower Methow tributaries intensive effectiveness monitoring study. Interim report Lower Methow tributaries intensive effectiveness monitoring study. Interim report
Actions have been taken to replace diversion dams in lower Beaver Creek with a series of rock vortex weirs. Some of these diversion dams have been in place for over 100 years, and they have impaired or completely blocked upstream migration of fish. Three diversion dams were replaced in 2003 (Lower Stokes, Thurlow Transfer, and Upper Stokes), and a forth diversion dam was replaced in 2004...

Measuring the performance of two stationary interrogation systems for detecting downstream and upstream movement of PIT-tagged salmonids Measuring the performance of two stationary interrogation systems for detecting downstream and upstream movement of PIT-tagged salmonids
We tested the performance of two stationary interrogation systems designed for detecting the movement of fish with passive integrated transponder (PIT) tags. These systems allowed us to determine the direction of fish movement with high detection efficiency and high precision in a dynamic stream environment. We describe an indirect method for deriving an estimate for detection efficiency...

Field-based evaluations of horizontal flat-plate fish screens Field-based evaluations of horizontal flat-plate fish screens
Diversions from streams are often screened to prevent the loss of or injury to fish. Hydraulic criteria meant to protect fish that encounter screens have been developed, but primarily for screens that are vertical to the water flow rather than horizontal. For this reason, we measured selected hydraulic variables and released wild rainbow trout Oncorhynchus mykiss over two types of...
