Abstract
|
The 2008 Willamette Project Biological Opinion requires improvements to operations and structures to reduce impacts on Upper Willamette River Chinook salmon and steelhead, including evaluations of the feasibility of installing new juvenile collection and bypass facilities at three dams on the Willamette River in Oregon: Cougar, Detroit, and Lookout Point dams. Understanding the distribution of juvenile salmonids in the reservoirs will be critical for the development and operation of structures to pass fish safely and efficiently. This report describes results of mobile hydroacoustic surveys of fish distributions in Cougar Reservoir, a 518-ha impoundment behind Cougar Dam on the South Fork of the McKenzie River near Blue River, Oregon.
