Document Description
Salt Creek is an ephemeral creek that if not properly managed can allow flood waters to undermine the protection levees of the California Aqueduct compromising the integrity of the Aqueduct as well as inundate surrounding agricultural lands outside of USBR-owned (DWR managed) land and flood easements.
Vegetation will be cleared out of the channel bed of Salt Creek approximately one mile along Parkhurst road west of the 90 degree bend and continuing northeast in the existing low flow channel to the CA protection levee. Sediment that has deposited in the channel from recent flooding will be removed and placed on Parkhurst Avenue near the bend approximating a 2 feet increase in elevation along a 1,000 feet length. District staff will conduct a topographic survey to determine the volume of soil to be removed (approximate estimated volume is about 1,800 cubic yards). The vegetation within the small triangle area, owned by USBR, that is between Parkhurst Avenue and the Aqueduct will not be removed. Vegetation will be cleared from the immediate area of a gated inlet at milepost 136.00 of the California Aqueduct. Sediment blocking the gated inlet will also be removed (approximate volume is about 100 cubic yards) and the spoil will be placed on an existing mound adjacent to the levee. By maintaining this area, DWR can further protect water quality and water deliveries for downstream municipal and agricultural water users.
