image3Project Overview

The six counties of the Northern Sacramento Valley have been working together for over 10 years to lay the foundation for an integrated regional plan to address water-related issues such as economic health and vitality; water supply reliability; flood, stormwater and flood management; water quality improvements; and ecosystem protection and enhancement. The counties have completed the development of a valley-wide Integrated Regional Water Management Plan, and have committed to continuing the efforts of regional water management through this plan.

imageThe Integrated Regional Water Management (IRWM) is a collaborative effort to enhance coordination of the water resources in a region. IRWM involves multiple agencies, stakeholders, tribes, individuals and groups to address water-related issues and offer solutions which can provide multiple benefits to the region. Representatives of the six counties are working in partnership with community stakeholders, tribes and the public to identify the water-related needs of the region. This information was used to develop goals and objectives of the IRWM Plan, and the identification of projects and programs to be included in the Plan. The Plan was adopted in April, 2014, and will better position the region and local partners to receive funding for high-priority projects.

Northern Sacramento Valley Integrated Regional Water Management (NSV IRWM) Board

Beginning in March 2012, their regular meetings moved to the first Monday of the months of March, June, September and December. In 2019, the meeting schedule was amended to two meetings per year, or more as needed. The Board consists of two appointments made by each of the six Boards of Supervisors in Butte, Colusa, Glenn, Shasta, Sutter and Tehama Counties, for a total of twelve members plus alternate members as appointed.

The NSV IRWM Board worked with stakeholders throughout the region to develop an integrated regional water management plan (IRWMP) pursuant to the California Water Code §10450-10543. Initial tasks in the plan development were funded through a $100,000 USBR grant administered by RD 108, as well as $50,000 Proposition 50 state funding awarded to Butte County. The group was also awarded $900,000 of planning funding by the Department of Water Resources under Proposition 84. The contract for this funding was finalized in October 2011. Simultaneously, the sub-contract for the development of the IRWM Plan was awarded to West Yost Associates through a competitive process.
