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 canals 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

May contain: body part, hand, person, washing, and sink

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 each 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.

Watershed Sanitary Survey

May contain: water, nature, outdoors, creek, and stream

NID vows to continually provide safe drinking water. One aspect of that is to identify any deficiencies that may adversely impact the District’s water system.

The Yuba/Bear River Watershed Sanitary Survey identifies activities within the watershed that have a potential to adversely affect source water quality. These include activities located near water treatment plants or that are predominant in the watershed.

While the source water originating from the Yuba/Bear River systems continues to be of high quality, the 2021 Watershed Sanitary Survey update provides several localized efforts that will help to further enhance and protect source water supplies for the future.

Rain and Snowfall Data

With precipitation data that dates to the 1800s, NID is a foremost source for regional weather information.

NID has been keeping weather records for Bowman Reservoir (elev. 5,650 ft.) since 1929. The 69.2-inch annual average precipitation at Bowman compares to an annual average of 56 inches at 2,700 feet near Nevada City and 52 inches at 2,400 feet in Grass Valley.

Annual precipitation is measured for the 12-month period beginning July 1 and ending June 30.

NID is a participant in the California Cooperative Snow Survey Project. District snow surveyors conduct snow surveys regularly during the winter and spring months. Data compiled in the snow surveys is used to predict water availability locally and statewide.
