Water temperatures frequently exceed salmonid preference and survival thresholds in the Okanogan and Similkameen Rivers. Throughout the Okanogan Basin significant efforts are underway to improve tributary habitat for spawning and rearing, increase in-stream flows, and improve upstream water management through negotiations with Canada and the US co-managers. Gains have been made, but high water temperatures remain one of the most significant limiting factors in the Okanogan watershed, particularly from July through September.
The Driscoll Island project presents an opportunity to investigate and design cold water off channel refuge for juvenile salmonids that would be available during a critical time of year when water temperatures often drive juveniles to migrate to less favorable habitats.
