U.C. Davis study finds dams ineffective for conservation…

For many years, federal, state and corporate proponents of building more dams in California have touted cold water river releases provided by increased water storage behind dams as a key tool in “saving” struggling salmon and steelhead populations.

Yet a just published study by the UC Davis Center for Watershed Sciences, Dams Ineffective for Cold-Water Conservation– 8/25/21, has found that dams are ineffective for the cold water conservation that is needed to preserve imperiled salmon, steelhead and trout.

”Dams poorly mimic the temperature patterns California streams require to support the state’s native salmon and trout — more than three-quarters of which risk extinction,” according to the study published in the journal PLOS ONE by the University of California, Davis. “Bold actions are needed to reverse extinction trends and protect cold-water streams that are resilient to climate warming.”

The study helps identify where high-quality, cold-water habitat remains to help managers prioritize conservation efforts.
