NID Board Approves Grant Agreement for Studies of Hemphill Diversion Facility

Grass Valley – The Nevada Irrigation District Board Members on Wednesday (March 22) unanimously approved a grant agreement from the California Department of Fish and Wildlife (CDFW), for studies related to the Hemphill Diversion modification or replacement.

The grant from CDFW outlines items to be evaluated, including the study of fish within the project area, and is part of an ongoing assessment and alternative development for the facility. The grant agreement will help NID further understand the site and identify responsible alternatives to the partial fish migration barrier.

NID is dedicated to providing exceptional stewardship of the resources in the District’s care. Diversion alternatives are being explored to increase habitat for native anadromous species.

Project objectives include development and oversight of a Technical Advisory Group, hydraulic analysis, a sediment transport study, baseline water quality data, and two seasons of adult Salmon, Steelhead, and Redd surveys, conducted above and below the diversion site in Auburn Ravine.

The District has issued a Request for Proposals for water quality and fish studies, due March 31, 2017. The Hemphill Diversion Project includes a $177k CDFW grant, along with $118k in funds provided by NID.

The complex Hemphill diversion project is expect to be completed in 2020. Friends of Auburn Ravine representative, Jim Haufler, expressed appreciation to the Board for the thoroughness of the work already completed, and for taking the time to consider the consequences, avoid mistakes, and get it done right.

In other business, Board Members:

• approved a mitigation monitoring and reporting program for the Newtown Reservoir Cleaning Project.
• approved further evaluation of NID’s potential involvement in the West Placer Groundwater Sustainability Agency.

The next regular meeting of the NID Board of Directors will be held at 9 a.m. on Wednesday, April 12, at the NID Business Center located at 1036 West Main Street, Grass Valley. NID Board meetings are open to the public.
