The Imperial Irrigation District has constructed 10 regulating reservoirs as part of its ongoing water conservation program. The reservoirs receive water that would normally be surplus and store the water for beneficial use when needed. Together, the district's reservoirs have a storage capacity of more than 3,300 acre-feet (AF) of water. 

Kakoo Singh
The Kakoo Singh Reservoir, the first reservoir constructed by the district, regulates water from the East Highline Canal. The water is diverted into the Vail Supply Canal via gravity flow and back into the East Highline via pump flow. This reservoir, which was named after a local farmer, is located next to the East Highline, near the Vail Supply Heading and above the Nectarine Check.

J.M. Sheldon
The Sheldon Reservoir, located on the Westside Main Canal off Forrester Road, northwest of Imperial, takes surplus water from the Westside Main. This reservoir was named for a long-time district employee, J. Melvin Sheldon, who was manager of the water department from 1966 to 1976.

Oscar Fudge
The Fudge Reservoir is on the Central Main Canal near Brawley. O.L. "Oscar" Fudge was a water department manager who retired in 1966.

H. "Red" Sperber
The Sperber is located west of Holtville on Meloland Road. Water from the Rositas Canal is held and released when needed into the Rose and Rubber canals. The reservoir was named after Herman "Red" Sperber, a local farmer and long-time member of the Imperial County Board of Supervisors.

Robert F. Carter
The Carter Reservoir is designed to conserve operational discharge from the end of the Westside Main Canal. Located adjacent to Highway 86, six miles north of Westmorland, the reservoir also features a computerized control system and a specially designed area for recreational fishing. A five-foot dike impounds water within the fish habitat area. The dike is 1,000 feet by 110 feet with a sandy beach for fishing access. Robert F. Carter served as the district's general manager from 1959 to 1977.

Bernard Galleano
The Bernard Galleano Reservoir is located at the terminus of the East Highline Canal just north of Niland. Farmland beyond this point is supplied water via the Niland Lateral Canal Extension. The location of the reservoir, and the fact that it is totally automated and self-controlled, allows the IID to balance water shortfalls and overages in the East Highline Canal, thus providing more uniform water deliveries to all downstream users. The reservoir was designed with an enhanced fisheries habitat and test site for waterfowl habitat development. The reservoir was named after Bernard Galleano, former Calipatria area farmer and member of the IID Board of Directors.

Carl C. Bevins
The Carl C. Bevins Reservoir stores operational discharge from the eight lateral canals in the Plum-Oasis Lateral Interceptor system. Two 25-cfs pumps draw water out of the reservoir for downstream users and have a back-flow ability to draw excess water out of the downstream canal for storage in the reservoir. The Bevins Reservoir, located east of Imperial, is part of a project that provides farmers a virtual demand delivery system where they can shut off or receive water whenever they want.

Young
The 275 acre-foot Young Reservoir was constructed as part of the Mulberry-D Lateral Interceptor Project under the 1989 IID/MWD Water Conservation Program Agreement. The Mulberry-D Lateral Interceptor is approximately 8.25 miles long and catches operational discharge at the ends of 11 lateral canals serving 31,000 acres of farmland. The reservoir is located near Calipatria at the end of the interceptor canal to store water for downstream users. The Mulberry-D Lateral Interceptor Project conserves about 7,650 acre-feet of water annually. The Young family name was chosen in recognition of their dedication and contributions to the Imperial Valley during their three generations of farming.

Milas Russell, Sr.
The 200 acre-foot Russell Reservoir is part of the Mulberry-D Lateral Interceptor Project, a 1989 IID/MWD Water Conservation Program Agreement. The Mulberry-D catches operational discharge at the ends of 11 lateral canals that serve 31,000 acres of farmland near Calipatria. It is approximately 8.25 miles long. This lateral interceptor project conserves about 7,650 acre-feet of water annually. The Russell Reservoir stores water for downstream users and is located on the Vail Canal. The reservoir was named after Milas Russell Sr., a dedicated farmer who transformed marginal land into productive farm ground and was a leader in community service.

Louise K. Willey
The 300 acre-foot Willey Reservoir was constructed as part of the Trifolium Lateral Interceptor Project under the 1989 IID/MWD Water Conservation Program Agreement. The Trifolium Lateral Interceptor is approximately 10.9 miles long and catches operational discharge at the ends of 15 lateral canals serving 30,000 acres of farmland. The reservoir is located on the south side of the New River opposite the end of the Vail Canal. This reservoir stores the operational discharge from the interceptor and pumps the water through a 45-inch in diameter pipeline 3.5 miles long upstream on the Vail Canal. The water is then discharged into the Vail Canal at the Vail Lateral No. 3 Heading for downstream users. The Trifolium Lateral Interceptor Project conserves about 10,700 acre-feet of water annually. The reservoir was named for Louise K. Willey for her outstanding contribution to the local agricultural industry and to the people of the Imperial Valley.
