California Trout

Document Description
The purpose of this Project is to prevent fish from entering diversion ditch "Ditch 43" on French Creek by relocating the existing screen closer to French Creek. The current screen is approximately 1,500 feet down ditch from the head gate on French Creek. Coho salmon rear near the existing head gate throughout the irrigation season and frequently get entrained in the ditch, unable to make it to the existing screen and nonfunctional fish bypass pipe to return safely to French Creek. The new fish screen will be 30 feet down ditch from the head gate, and the new fish bypass pipe will be approximately 75 feet in length and will return any fish that enter the ditch back to French Creek just downstream from the head gate.
