Science Friday (PART ONE): Disappearing Steelhead – The Fate of Summer Steelhead Seeking Coldwater in the Columbia and Snake Rivers

In the Columbia and Snake rivers hydropower systems, many migrating summer steelhead overshoot their spawning streams, passing dams multiple times and increasing mortality rates, trying to find cold water refuge. We look at the ramifications on steelhead management for not properly accounting for these overshoot steelhead.
