Document Description
Dam Safety Services staff will perform valve exercises at the Patterson Dam outlet works. The Division of Safety of Dams (DSOD) requires that valves associated with the outlet works be exercised on an annual basis to verify the ability to dewater the reservoir. To avoid a sudden release of water to the drainage ditch, the conduit between both valves will require controlled low flow release of water and will be limited to 10 gpm. Staging will be on existing roadways. All work is within DWR right of way.
