In 2003, Ducks Unlimited completed delivery of the Klamath Basin Wetlands NAWCA Project. This project included work at eight sites, including the Shasta Valley Wildlife Area (WA). The overall Project collectively protected, restored, or enhanced more than 24,000 acres of wetlands and associated uplands in the Klamath Basin. Major funding for this work was provided through a North American Wetlands Conservation Act (NAWCA) grant. In addition to NAWCA, DU's Project partners included Rocky Mountain Elk Foundation, California Wildlife Conservation Board, California Department of Fish and Game, U.S. Forest Service, U.S. Bureau of Reclamation, Natural Resources Conservation Service, and the U.S. Fish and Wildlife Service.
Work conducted on the Shasta Valley WA component of the Project improved 130 acres of wetlands and 225 acres of uplands. Work consisted of constructing levees and waterfowl nesting islands, installing water control structures, repairing water delivery ditches and levees, and conducting site preparation and seeding native grasses. Work also included substantially re-contouring the main irrigation ditch and to increase water-use efficiency and improve overall wetland management capabilities at Shasta Valley WA.
DU's work at Shasta Valley WA continued after initial delivery of the Klamath Basin Wetlands Project. DU has completed a comprehensive master plan for the area's entire water conveyance system. The plan evaluates the current water conveyance system and provides recommendations on how to modify the system to improve water and vegetation management capabilities and thereby improve wildlife habitat throughout the area.
