Integrated Status and Effectiveness Monitoring Program - Entiat River Snorkel Surveys, 2006-2007.
The USFWS Mid-Columbia River Fishery Resource Office conducted snorkel surveys at 11 sites during the summer 2006 survey period and at 15 sites during fall 2006 and winter 2007 survey periods as part of the Integrated Status and Effectiveness Monitoring Program in the Entiat River. A total of 39,898 fish from 14 species/genera and an unknown category were enumerated. Chinook salmon were the overall most common fish observed and comprised 19% of fish enumerated followed by mountain whitefish (18%) and rainbow trout (14%). Day and night surveys were conducted during the summer 2006 period (August), while night surveys were conducted during the fall 2006 (October) and winter 2007 (February/March) surveys. This is second annual progress report to Bonneville Power Administration for the snorkel surveys conducted in the Entiat River as related to long-term effectiveness monitoring of restoration programs in this watershed. The objective of this study is to monitor the fish habitat utilization of planned in-stream restoration efforts in the Entiat River by conducting pre- and post-construction snorkel surveys at selected treatment and control sites.
