Scotts Flat Powerhouse

As the world seeks to tackle the growing threat of climate change, and California’s goal is to convert to 100 percent clean energy by 2045, the Nevada Irrigation District (NID) is doing its part. The District announced it will begin using 95 percent clean, renewable energy to power all its operations. The move became effective in June.

To accomplish this, NID has changed where it gets its power, switching from PG&E (which provides only about 33% renewable) to the clean, renewable hydropower the District generates at its Scotts Flat Powerhouse. In addition to the environmental benefits, the cost of energy will be stabilized, insulating NID customer’s from PG&E rate increases.

“NID is a leader among water agencies in the production of clean, renewable hydropower and, with this change, we become a leader in the use of that clean, renewable power,” stated Keane Sommers, Manager of Hydroelectric Operations. “This step is also further evidence that NID is acting on its sustainability policy that calls for NID to become more socially, environmentally, and economically sustainable.”

While most of the NID facilities in Nevada, Placer, and Yuba Counties including the main administrative building and the water treatment plants will be using 100% clean renewable power, some smaller facilities still need to be converted leaving NID just short of 100% overall.

NID views this transition to green energy as just the beginning. In the 1960’s the community invested in NIDs hydroelectric powerhouses and, in the future, NID looks forward to making this clean, renewable power available to other local users at better than PG&E rates.
NID is a leader among Northern California water agencies in the production of clean renewable hydroelectric energy. It operates seven hydroelectric plants and 12 miles of overhead power lines that deliver 83 Megawatts of clean, renewable energy to the power-grid. Every year the revenue from hydroelectric sales offsets water rates for the District’s 30,000 customers in Nevada, Placer and Yuba counties. We deliver water for clean energy.


NID BOARD FORMS COMMITTEE TO CONDUCT GENERAL MANAGER SEARCH – Interim General Manager Appointment Expected June 11

June 3, 2020

(Grass Valley, CA June 3, 2020) — The Nevada Irrigation District Board of Directors met in a special, closed session today and reported out following the meeting that they had created an ad hoc General Manager Search Committee. The Board of Directors selected Board President Ricki Heck and Board Vice President Chris Bierwagen to serve on the Committee. The Board delegated to the Committee the authority to appoint an interim General Manager, expected June 11, and to work with the Human Resources Department Manager to initiate a search for a permanent General Manager.

This action was taken in response to the news last week that the current NID General Manager, Remleh Scherzinger, had tendered his resignation to become the new General Manager of the Tahoe Donner Public Utility District.

NID Irrigation Water Season Underway: Water Begins to Flow to Fields and Farms on April 15

April 14, 2020

Lone Star Canal

Like it has for generations, the Nevada Irrigation District (NID) is ready to begin seasonal irrigation water deliveries to customers throughout Nevada and Placer counties. This year the water is scheduled to start flowing on Wednesday, April 15.

NID’s 500 miles of canal deliver irrigation water to about 5,600 customers who irrigate more than 30,000 acres of farms and fields. Most purchase their water on a seasonal basis during the irrigation season, which runs from mid-April through mid-Oct. 14. In addition, NID’s deliveries fill ponds and reservoirs for stock watering, fire suppression and recreation.

At the April 8 meeting, NID Directors supported the declaration for surplus water. Reservoir storage is at 212,289 acre-feet – 95 percent of average – as of March 31. In total, the forecasted available water supply for the year is 291,000 acre-feet, well above the 235,700 acre-feet threshold for normal operations.

“As everyone knows, it’s been a dry winter. We’ve finally received precipitation to give us some breathing room. Data supports we have an ample supply of water, so we can declare a surplus water supply,” Operations Manager Chip Close told Directors during the April 8 meeting.

NID’s irrigation water customers connect into the canal systems to irrigate pastures for cattle, sheep and horses, as well as on farms to grow crops, ranging from grapes, apples and citrus to berries and corn. In addition, and importantly, NID’s raw water deliveries fill ponds and reservoirs for stock watering, fire suppression and recreation throughout the District.

For nearly 100 years, the Nevada Irrigation District has been delivering 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 snowmelt 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 27 reservoirs later moving it through one of seven 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. We deliver water for life. Learn more at

Community input makes the difference: thanks to all who have helped update NID’s Strategic Plan

December 11, 2019

The ink is nearly dry on the update to Nevada Irrigation District’s (NID) Strategic Plan, as members of the community have teamed up with elected Directors to craft the document that provides overall direction, establishes goals and sets priorities for the District.

More than 60 residents have participated during four two-hour workshops since September. In total, that’s about 480 workshop-hours of community involvement. The most recent meeting was held on Tuesday evening. December 10.

In a facilitated workshop format, NID customers and residents have given input about the District’s mission and how to express what the District wants to accomplish now and in the future. Directors will use these suggestions to form the final update to the Plan.

“We are so thankful for all the input,” said NID Assistant General Manager Greg Jones. “We’ve received such valuable information and so many tremendous suggestions from the community. We appreciate the community’s interest and contribution to help the Directors update the District’s Strategic Plan.”

Among the workshop participants was Debbie Porter, who has been an NID customer for more than 22 years and is the president of the Golden Oaks Homeowners Association, a community of 100 parcels in southern Nevada County: “I think it’s a really good idea to get public input. It’s important to have a balance of viewpoints and opinions.”

Here are the Strategic Plan draft statements, which Directors will review for adoption in January:

Mission Statement: The District will provide a dependable, safe, sustainable and resilient water supply while being good stewards of the watershed.

Vision Statement: NID will promote healthy watersheds and reliable infrastructure that support our environment, treated and raw water customers, power reliability and recreation to sustain our quality of life; now and in the future.

Value Statements:
• Safety: Safety is integrated into our culture and is the first priority among all aspects of our work.
• Fiscal: Operate the District Finances with strong fiscal responsibility and transparency to ensure that NID’s finances are spent on those activities that support the mission and vision of the District.
• Resources: Maintain healthy watersheds through the implementation of Best Management Practices in collaboration with our strategic partners.
• Customers – Make decisions that serve the best interests of District ratepayers.
• Employees: Maintain and foster a viable workforce through fair compensation packages and a stable work environment.
• Decision-making: Use the best available science to make informed management decisions. Engage collaboratively with staff, the scientific community, agricultural community, and the informed lay communities that we serve. Use generally accepted business practices in our planning and project development actions.
• Transparency: Inform, educate, listen to and collaborate with our communities in our endeavors and activities with honesty and integrity.

NID Directors and community members work together during the Dec. 10 workshop.

Local Power Solutions Workshop – community called to convene for a public discussion on Oct. 29

October 24, 2019

A groundswell of local voices are calling for the community to come together and discuss an alternative power solution for the region. In response to these requests, NID has organized a public workshop for Tuesday, Oct. 29 from 6-8 pm at the District’s Board of Directors boardroom in Grass Valley.

The recent power outages are having widespread effects on our community, resulting in increased urgency to explore local solutions. Taking stock of the impact and gathering input is needed from all voices in the region, from residents, schools, businesses, to local government.

The workshop will take place at 1036 West Main Street in Grass Valley on Tuesday regardless of PG&E’s power service status due to NID’s back-up power generators. Up to 85 people are able to be accommodated in the NID board room with unlimited spill-over capacity in the parking lot adjacent to the building. Accommodations will be made so all workshop participants can provide input.

Tour showcases the Combie Sediment & Mercury Removal Project

September 25, 2019

Representatives from agencies and organizations involved in the work to remove sediment and mercury at Combie Reservoir got a special 3-hour tour in August to see first-hand how the project has progressed.

This summer, a suction dredge has been used to suck up sediment from the water and then put through a centrifuge to separate any elemental mercury.

About 20 participants got a tour of the different operations involved in the process. While everyone was familiar with the project, based on their own work, seeing how the whole process has come together was rewarding.

Mercury was introduced to the Sierra Nevada during the Gold Rush period of the 1800s and used to process mining ore for gold. That mercury has remained and led to contamination of sediments throughout Sierra watersheds.

Findings from this project will become valuable to state regulators and help water managers address mercury in the aquatic food chain. When complete, this project can be replicated in other impacted reservoirs.

NID is working with these partners: the Sierra Fund, US Geological Society, the Department of Water Resources, the Cosumnes-American-Bear-Yuba Integrated Regional Water Management Group (CABY), NV5 Global, Inc., Great Lakes Environmental and Teichert Aggregates.

Reminder: Join us for the first NID Strategic Plan public workshop next Tuesday evening

August 29, 2019

Please join us next Tuesday evening for the first public workshop to focus on the update to the Nevada Irrigation District’s (NID) Strategic Plan.

The meeting will provide information about the Plan, and allow participants to offer input as part of the update process.

The Strategic Plan provides overall direction of NID, and sets the District’s guiding policies. It affirms the District’s core mission to provide a dependable, quality water supply while continuing to be good stewards of the watersheds and conserving the available resources in our care.

The current Plan also identifies four main District goals:

  1. Continued health of the District is dependent upon the proactive management of our physical, financial, and human resources.
  2. Stewardship of District resources requires a collaborative and responsive relationship with our Local and Regional community.
  3. Developing and managing our resources in a self-determining manner protects and provides for local control of our community’s most valuable assets – a fairly priced and available water supply.
  4. Integration of proven practices and technologies enhances efficiency and reliability throughout the District.

The current Strategic Plan remains in effect until updated and adopted by NID’s Board of Directors.

The Sept. 3 workshop is from 6-8 NID’s main office, 1036 W. Main Street in Grass Valley.

A second public workshop will be held Sept. 17 from 6-8 the main office. Both meetings will be managed by a professional facilitator. Both meetings will be livestreamed.

Quagga and Zebra Mussel Prevention and Monitoring Program

April 12, 2019

The Program aims to assess the current vulnerability and prevent the introduction of quagga and zebra mussels (dreissenid mussels) into three lower-elevation storage facilities: Scotts Flat, Rollins and Combie Reservoirs.

Funding was obtained through a grant with the Department of Boating and Waterways (DBW) to develop a Vulnerability Assessment and Prevention/Monitoring Plan

The Program assesses the vulnerability of these reservoirs to the introduction of non-native dreissenid mussel species by:
* Monitoring the number of visitors
* Inquire as to the origin of visitors (relative to Dreissenid infested waters)
* Monitor outside equipment that is allowed (rentals)
* Survey the duration of use (day use, slipped/moored)
* Monitor access (managed or unmanaged)
* Prevention efforts being implemented
* Education efforts being implemented

The program is designed to prevent the introduction of non-native dreissenid mussel species includes, at a minimum, all of the following:
* Public education consisting of handouts, flyers, signage, postings and verbal communication and education.
* Monitoring that consists of applying substrate for monitoring the adult and/or larval mussels and water quality conditions to determine viability of adult and/or mussels survival.
* Management of those recreational, boating or fishing activities that are permitted which may include: inspections, decontamination stations and/or information where to decontaminate a vessel, exit inspections and banding of vessels to trailers.
