About IRWM

Integrated Regional Water Management (IRWM) Planning began in 2002, with the passage of Proposition 50 by California voters. The bond, among other things, authorized spending $3.4 billion in general obligation bonds funds to construct a variety of water supply and water quality projects across the state. The IRWM program encourages voluntary cooperation in managing water resources within a region. IRWM involves multiple agencies, stakeholders, individuals, and groups; and provides a venue for local stakeholders to address the issues and differing perspectives of involved entities through mutually beneficial solutions.

By law, IRWM cannot impact local or regional water rights, nor can it override local plans and policies or the decisions of elected bodies. The process and plan is advisory only.

To access the available bond funds involves a three-step process: (1) formally identifying the region, (2) developing a plan to inform voluntary water management. And, 3) applying for project implementation funding. The IRWMP includes a list of projects proposed by local agencies and Tribes that could be funded to improve local conditions.

The California Department of Water Resources (DWR) has a variety of guidelines that cover IRWM and the preparation of Integrated Regional Water Management Plans (IRWMP). These guidelines show what DWR wants to see in each document and also what the contents of a funding application for projects must include.
