 Dredging

Dredging
Portions of West Canal, Middle River, Old River, Victoria Canal, North Canal, and Grant Line Canal would be dredged to improve conveyance and/or the operation of private agricultural siphons and pumps. In total, up to 300,000 cubic yards of material would be dredged and spoiled within the south Delta. Dredging would be conducted in the center of the channel to avoid wetland plants and riparian habitat.

Gate Dredging
Dredging within the footprint of the gate would be necessary to clear the channel bottom for gate placement. Up to 150 feet upstream and 350 feet downstream from each gate site would be dredged using a sealed clamshell, as described below, to clear the area for construction and placement of the gate. In total, up to 6,000 cubic yards of material would be dredged at the gate sites. The dredging of the upstream and downstream areas would avoid sensitive habitats such as tidal emergent wetlands and riparian areas. Dredging would occur between August 1 and November 30, lasting approximately 15 days at each gate site (more...)
