Reclamation District No. 833 (RD833) was initially formed in 1921 under the State Reclamation Act. The District provides flood control services to approximately 38,000 acres of agricultural and single-family residential parcel owners in the Biggs and Gridley area. While the District consists primarily of intensive agriculture in the form of rice farming, the District also includes a portion of the urbanized areas of Biggs and Gridley. Additionally, the District owns and operates a 720-acre property in the Butte Sink area located in Sutter County for drain-water management, duck hunting and farming.
The western portion of the District is within the Cherokee watershed and the eastern portion of the District is within the Feather River/Lower Honcut watershed. Portions of the District have been mapped within a number of dam failure inundation zones, including Shasta Dam, Whiskeytown Dam, Black Butte Dam, Oroville Dam and Thermalito Forebay and Afterbay.
