Nevada Irrigation District (NID) is an agency in Northern California that supplies water for much of Nevada County and portions of Placer and Yuba Counties. The water is used for irrigation, municipal and domestic purposes. It was established in 1921.
The Nevada Irrigation District owns and operates ten reservoirs, the largest being Jackson Meadows Reservoir, Bowman Reservoir and Rollins Reservoir, respectively. The district also has seven hydroelectric plants. However, it is not an electrical utility like many of California's irrigation districts.
