Document Description
Delta Field Division (DFD) will perform maintenance at Patterson Reservoir. DFD staff will pump sediment laden water from Patterson Reservoir into the engineered, asphalt lined retention pond to allow for inspection of the Patterson Reservoir liner. The sediment will be allowed to dry in the basin before removal. Once dry, DFD staff will load the sediment using a water truck for dust control, then transported offsite to the nearest waste disposal site. Total area of the sediment basin is approximately 0.67 acre. Equipment staging will be on the paved roadway surface. All work is within DWR right of way.
