From Mountain Top to Your Tap

For 100 years, the Nevada Irrigation District has been delivering high quality water to our customers in Nevada, Placer and Yuba counties. What began as an old reservoir and canal system serving gold mines has been transformed into a modern water distribution system. NID water originates as snow melt found in 70,000 acres of high elevation watershed near the headwaters of the Yuba River, Bear River and Deer Creek.  NID stores water in 29 reservoirs later moving it through one of six treatment plants and hundreds of miles of canal and pipe to become drinking and irrigation water for 25,000 homes, farms and businesses.  The annual result is three billion gallons of high quality drinking water for our customers and 30,000 acres of irrigated agricultural land that is used to grow multiple crops including wine grapes, nursery stock, apples, rice, plums, citrus, grass, alfalfa hay, as well as to irrigate pasture.


Water Provided by NID Consistently Meets and Exceeds Water Quality Standards

Drinking water supplied to Nevada Irrigation District (NID) customers continues to meet and exceed state and federal public health standards, based on testing results that serve as the basis for the District's Water Quality Report.

The report, also known as the Consumer Confidence Report, summarizes NID’s water quality monitoring and testing programs for the 2020 calendar year. The information focuses on water supplied through the Elizabeth L. George, Loma Rica, Lake Wildwood, Lake of The Pines, North Auburn water treatment plants.
