Fishing for Climate Data: How Recent Research is Helping Forecast Changes in Salmon and Trout Habitat

fishing on snake riverScientists at the Rocky Mountain Research Station’s Aquatic Sciences Lab compiled temperature records from more than a dozen natural resource agencies monitoring nearly 400 sites along large rivers in the northwestern United States to understand climate change impacts on salmon and trout river habitat. We found that average river temperatures during summer and early fall months rose about 1 °C over the 40-year period of 1976 to 2015. River managers may be able to offset warming in some areas and preserve coldwater river habitats by employing various habitat and flow restoration techniques including minimizing flow diversions, increasing shade, enhancing habitat diversity and the number of deep pools, releasing cold water from storage dams during heat waves, and improving fish passages at dams that block access to cooler river sections.

Removal of non-native trout in the Carson-Iceberg Wilderness Area

nullAugust 2015 -The Humboldt-Toiyabe National Forest successfully removed non-native trout from 11 miles of historic Paiute cutthroat trout habitat in Silver King Creek in the Carson-Iceberg Wilderness Area. Non-native trout all but eliminated Paiute cutthroat trout in this creek over 80 years ago and the species was listed as threatened under the Endangered Species Act in 1975. Planning for this treatment to fulfill the requirements for the species to be delisted began over 10 years ago and required special measures to protect wilderness values and characteristics. The endangered Paiute cutthroat trout lives nowhere else in the world except on the Carson Ranger District.  Additional project information can be found on the California Department of Fish and Wildlife web site.  


The Salmon-Challis Makes a Big Difference for Fish

The Salmon-Challis National Forest has teamed up with the Bureau of Reclamation, Trout Unlimited, and the Shoshone-Bannock Tribes to restore fish habitat in the Yankee Fork of the Salmon River.
