AI Contract Overview

The California Department of Water Resources San Joaquin Field Division is conducting the 2026 DEPP Dredge Work and Sump Maintenance project located in Lost Hills, Kern County. This project is essential for maintaining the Devil's Den Pumping Plant forebay to ensure continued water deliveries for the California Aqueduct and State Water Project. The scope of work includes dredging the forebay using a Toyo pump and crane to transfer mud and silt into the sump, repairing erosions with fill material and compaction equipment, and removing vegetation and sediment from the sump using a variety of heavy machinery including excavators, dozers, and graders. Dredging activities are scheduled for November 2026 and are expected to take two weeks to complete. Sediment removed from the sump will be transported to the DEPP spoil site via dump trucks, and water trucks will be utilized for dust control and compaction aid. The project is classified under NAICS code 237990 and has been granted a Notice of Exemption from environmental review as it consists of necessary maintenance activities. Elizabeth Maldonado serves as the primary point of contact for this effort.

Full Description

San Joaquin Field Division plans to dredge the Devils Den Pumping Plant (DEPP) forebay, repair erosions, and remove vegetation and sediment from the DEPP sump. To complete the dredging activity, DWR staff will attach a Toyo pump to a crane. The crane will lower the pump into the DEPP forebay. The pump will then transfer water, mud, and silt through a hose and into the DEPP sump. This work is anticipated to take two weeks to complete. To complete erosion repairs, a dump truck will bring in fill material. A backhoe will fill and compact erosions. A water truck will be used to control dust and aid in compaction. To complete vegetation and sediment removal from within the DEPP sump, a backhoe, grader, long reach excavator, skid steer, front loader, and dozer will be used. A dump truck will transport sediment to the DEPP spoil site, and a water truck will be used to control dust and aid in compaction. Dredging activities will take place in November 2026. This work is necessary to maintain the forebay and to continue to make water deliveries.
