The Gray Lodge Wildlife Area is owned and managed by the California Department of Fish and Game (DFG). The Central Valley Project Improvement Act (CVPIA), Public Law 102-575, Title 34, Section 3406(d), directs the Secretary of the Interior through the Bureau of Reclamation (Reclamation) to deliver specified quantities of water to 19 refuges located in the Central Valley, including Gray Lodge Wildlife Area (WA). Reclamation is obligated to annually deliver water in specific quantities to the boundary of the Gray Lodge WA, meeting both scheduling and timing needs as determined by DFG. Reclamation and DFG have developed a strong working relationship and partnership through their combined efforts towards meeting the goals of CVPIA.

The Gray Lodge WA receives both surface water and groundwater supplies. Reclamation is able to provide surface water supplies to the Gray Lodge WA through a partnership with the Biggs-West Gridley Water District (District). These water supplies are conveyed through the District's facilities to three points of delivery (POD) on the northern boundary of the Gray Lodge WA. The POD are: Rising River, Cassidy, and Schwinn. Water flow meters are positioned at each of the POD for the purpose of measuring water amounts delivered. The information collected by these water flow meters is provided on this Web site.

BIGGS - WEST GRIDLEY WATER DISTRICT
Biggs-West Gridley Water District (District) is located in Gridley, California, and was founded in 1943 when the local landowners bought approximately 29% of the waterways and water rights from the Sutter Butte Canal Company. The District is currently comprised of approximately 32,000 acres, of which approximately 29,000 acres are irrigated annually. Approximately 85% of the District is planted to rice with the remainder consisting of orchard, pasture and alfalfa.

The District holds 160,950 acre feet of pre-1914 water rights from the Feather River, which is diverted from the Thermalito Afterbay of Oroville Dam through the Sutter Butte Main Canal. The District consists of three main laterals through which water is diverted into smaller waterways to service all of its members, including Gray Lodge Wildlife Area.

Biggs-West Gridley Water District is governed by a five-member Board of Directors and operates with a general manager and a staff of four ditch tenders and one maintenance worker.
