How is the reservoir's water used, and can more water be used for fish downstream?

Chabot Reservoir water is stored for emergency supply, recreational use, maintenance of flows downstream, and to provide irrigation water for two golf courses. The emergency supply could be used for drinking and/or for fire suppression. Water from Chabot Reservoir has been used for fire suppression on multiple occasions, and at least once in the last ten years. San Leandro Creek, downstream of Chabot Dam, runs through a heavily urbanized area, has been channelized for flood control, and there are man-made weirs and other structures on the creek. Releasing additional water for fish downstream is not likely to improve fishery conditions unless additional downstream improvements are made to restore the creek to a natural state. Any additional releases will reduce storage for other needs.
