Some Effects of Power Peaking on Fish in the Hanford Reach of the Columbia River

摘要

Flows in the Hanford Reach of the Columbia River are controlled and regulated at an upriver dam, particularly for the purpose of power-peaking. Effects of acute water-level fluctuations are evident in shoreline zones. Chinook salmon and smallmouth bass are valued species that are effected. While specific impacts have been identified on early life stages of these species, no quantification of impacts at the adult population level has been made. (ERA citation 08:004587)
