Background
In Miners Ravine, an upstream tributary of Dry Creek, the 20-foot-high Cottonwood Dam, situated in the Hidden Valley residential subdivision of Placer County, creates an impassable barrier to migrating salmon and steelhead.
Project
The Hidden Valley Homeowners Association requested assistance with fish passage at Cottonwood Dam. As a first step, DWR completed a barrier inventory and stream habitat quality survey upstream and downstream of Cottonwood Dam to help determine whether any benefits for salmonids could be gained by providing access to upstream reaches.
