Document Description
DWR staff will dewater the Devil Canyon Second Afterbay to perform an inspection of the wasteway gates. Water in the afterbay will be released using the afterbay’s wasteway gate outlet. This water will be released at a rate below a maximum of 400 cfs with an average rate of 370 cfs. The water will flow into the Devil Canyon channel and into the Sweetwater Percolation Basin. It is estimated that 118 acre-feet will be released into the natural flood channel and will require approximately 4 hours of sustained flow. Staging and access will be on existing roadways and parking lots. All work is within DWR right-of-way.
