Canadian Lower Columbia River: Fish Stranding Risk Assessment and Response Strategy
Author: Golder Associates Ltd
The primary objective of the Lower Columbia River: Fish Stranding Risk Assessment and Response Strategy is to mitigate the effects of flow reductions from HLK/ALH and BRD/X on native fish species through planning. The Strategy focuses specifically on fish impact mitigation procedures for planning and responding to flow reductions from HLK/ALH and the Kootenay River (BRD/X). The Pend d’Oreille River (WAN is owned by TML and BCH) is excluded as a source of fish stranding because there is only 600 m of influence prior to reaching the US border. Fish habitat dewatered due to dam operations can result in the stranding of fish eggs, juvenile fish and adults of some species. While it is recognized that there are a number of downstream industrial, commercial, residential and recreational interests that may also be affected by low and/or high water levels (e.g., access, river navigation, safety, flooding and bank stability), these issues are considered outside the scope of this strategy and are dealt with by the dam owners under separate processes (BC Hydro 2007).
