The water overtopped the berm and flowed down the adjacent hillside to Alameda Creek. Part of the berm was sloughed off and carried with the water towards the creek. Water also reached an area called "Creek Crossing" where Calaveras and Alameda Creek intersect. The quantity of water that was discharged is unknown. MVR suspects that the discharge was caused by non-synchronized pumps. Estimated quantity of discharge: 10,007 gallons.
