Arrow Lakes Tributary Fish Migration Access Assessment and Monitoring Program

Ecoscape is currently under contract by BC Hydro and Power Authority to complete Program No. CLBMON-32A, Arrow Lakes Tributary Fish Migration Access Assessment and Monitoring Program. This project includes an extensive literature review and Summary of Knowledge Report. The summary of knowledge report summarizes existing reservoir operations (i.e., drawdown) and research studies completed to date for the Arrow Lakes tributaries on the three fish species of concern - rainbow trout (Oncorhynchus mykiss), bull trout (Salvelinus confluentus) and kokanee (O. nerka). As part of the first phases, GIS mapping and data gaps were used to prioritize tributaries for assessment. Field inventories from 2009 to 2012 have been completed and Ecoscape has completed data processing and provision of a monitoring summary during each year of survey. Field inventory efforts focused on a topographical survey of low reservoir operating levels to optimize field inventory and mapping and identify low water elevation passage barriers to rainbow trout, which may otherwise not be apparent during higher reservoir levels. Field inventories also occurred during bull trout and kokanee spawning migrations. Phase 3 is currently in progress and involves operational analysis and reporting to BC Hydro and Power Authority.
