Document Description
DWR's San Luis Field Division (SLFD) will repair erosions, remove vegetation, and will remove approximately 150 cubic yards of sediment from the following toe drains at the O'Neill Forebay Dam: 132+45, 132+70, 132+80, and 134+75, as well as from the ditch extending approximately 800 feet west of the drain boxes. This work will return the capacity and operation of the drains and ditch to design specifications. Removed sediment will be used to fill erosions on the ditch slopes and will be compacted using an excavator or backhoe. Vegetation and sediment will be removed by excavator or backhoe. All removed vegetation, and any sediment not used to repair erosions, will be temporarily placed adjacent to the ditch until dry, and will then be transported by dump truck to the SLFD spoil pile at the B.F. Sisk Dam. State Water Project users will benefit.
