Description
Summary:The U. S. Army Engineer District, Portland, funded this research to evaluate possibilities for standardizing hydroacoustic methods for estimating fish passage through U. S. Army Corps of Engineers dams on the lower Columbia River, Washington and Oregon. The effort included this standardization workshop involving experts with fixed-aspect hydroacoustics, statistics, or fish passage. The goal of the workshop was to increase the consistency and comparability of fish-passage estimates by different researchers among sites and years by identifying important considerations and guidelines for hydroacoustic sampling, data processing, and data analysis. The 2-day workshop was held in Cascade Locks, OR, on 16 and 17 September 1997. Prepared in collaboration with Dyntel Corp., Vicksburg, MS. and AScI Corp., McLean, VA. Presented at Workshop on Standardizing Hydracoustic Methods of Estimating Fish Passage for Lower Columbia River Dams, Cascade Locks, OR, 16-17 Sep 1997.
