Illustration: Wild Steelhead Status Today
In 1996, NOAA fisheries separated West Coast wild steelhead populations into 15 Evolutionary Significant Units (ESU), or regional population groups with similar genetic, evolutionary and reproductive traits. More recently these have been defined as Distinct Population Segments (DPS). These separate distinctions allowed evaluation and listing, as necessary, of each ESU under the Endangered Species Act (ESA).
Wild Steelhead Research on the Sauk and Skagit Rivers
(This article was featured in the November 2010 issue of WSC’s newsletter, The Adipose.) By Chris Grieve Most of the Wild Steelhead Coalition members are aware that the Sauk and Skagit rivers were closed early the last two years during the winter seasons. Many of you probably didn’t know that…
WSC Position on Klamath Dams
The second largest river in California, the Klamath was once among the most productive salmon rivers in North America. Drawing its headwaters from Southern Oregon’s Klamath Lake it drains southwest into California before meeting with it’s largest tributary the Trinity and ultimately running to the Ocean north of Eureka. Early…
The impacts of hydro dams on steelhead
Dams impact steelhead in a number of ways. Dams block passage of salmon and steelhead as migrating juveniles on their way to the ocean as well as on their return to freshwater rivers to spawn (often hundreds of miles upstream). Some dams include fish passage via fish ladders, although the…
