Description The “Columbia River Instream Atlas" identifies where fish may be struggling and why and where Ecology might have the most success with Instream flow investments. Three important factors aid in making streamflow enhancement decisions: habitat, streamflows, and the amount of fish in a stream. The Atlas scores each of the three factors for portions of streams, called reaches, located in eight of the most "fish critical" watersheds in eastern Washington (WRIAs in the Walla Walla, Middle Snake, Yakima, Methow, Wenatchee, and Okangogan basins). The scores allow Ecology to tailor projects to make needed improvements and maximize returns.
