Formed in 1921, The Nevada Irrigation District is headquartered in Grass Valley, California, a picturesque and historic California Gold Rush town in the foothills of the Sierra Nevada, 60 miles northeast of Sacramento.

NID is an independent special district operated by and for the people who own land within its 287,000-acre boundaries. NID provides service in an expansive geographic area that makes the district one of the largest in the State of California.

The district is organized primarily to supply water for irrigation, municipal, domestic and industrial purposes. NID water is available in wide areas of Nevada and Placer counties; the district also has storage and distribution facilities in Sierra and Yuba counties.

Unique in many respects, NID collects water on 70,000 acres of high mountain watershed, owns and operates an extensive reservoir and canal system and network of water treatment plants. The district produces hydroelectric energy and provides outdoor public recreation.

As a state agency, NID operates under rules and regulations adopted under authority conferred by the California Water Code (Division 11. Irrigation Districts).  NID board meetings are conducted in public and the district’s records are open to public inspection during normal business hours.

NID is headquartered at an 18-acre site located on West Main Street in Grass Valley. The district also operates a maintenance yard on Gold Hill Road near Lincoln and a Hydroelectric Department office off Interstate 80 near Colfax.
