Document Description
The California Department of Fish and Wildlife (“CDFW”) proposes to perform maintenance activities on up to approximately 2.5 linear miles of the Lost Cannon Ditch, an irrigation ditch which conveys adjudicated water rights from Lost Cannon Creek to irrigated meadows on the Little Antelope Valley Unit of the Slinkard/Little Antelope Wildlife Area. This area burned during the 2020 Slink fire, which has experienced subsequent debris flows during precipitation events impacting the proposed project area. Maintenance activities will include cutting of vegetation (except healthy mature trees), and removal of infilled sediment. Vegetation work will be completed using hand tools, chainsaws, and a brush mower. A backhoe will be used to remove the sediment that was deposited in the ditch. No work will occur in flowing water and any spoils generated will be moved away from the ditch beyond potential high storm flows. Staging areas will be located within previously disturbed areas. Herbicide will be applied to the stumps of woody shrub species after cutting. If work is conducted between March 15th and July 31st bird clearance surveys will be conducted by a qualified staff biologist prior to beginning work. The purpose of the project is to increase the efficiency of this section of irrigation ditch and remove excess materials deposited from the debris flow.
