California has thousands of dams, from small earthen barriers to large dams hundreds of feet tall. More than 1,400 of those dams are large enough to fall under state safety regulations. A great number of them provide critical water supply, flood control, and hydroelectric power. But many have outlived their functional lifespan and the ecosystem and economic benefits of removal far outweigh the cost of leaving them in place.

By strategically pursuing opportunities for dam removal where economic, social, and environmental interests strongly align, CalTrout offers a model for restoring the health of the state’s rivers for the benefit of fish and people.

Top 5 California DAMS OUT

CalTrout’s Top 5 California DAMS OUT Report highlights five dams that are ripe for removal and that must, for the health of the ecosystem and communities around them, come out.

The Reconnect Habitat Initiative

Reconnecting Habitat is one of CalTrout’s key initiatives in its effort to return native fish to resilience. Removing barriers to fish passage and getting obsolete dams out are the key objectives. To learn more about the initiative, click here.
