Integrated Regional Water Management

The State of California defines integrated regional water management (IRWM) as:

“A collaborative effort to manage all aspects of water resources in a region. IRWM crosses jurisdictional, watershed, and political boundaries; involves multiple agencies, stakeholders, Individuals, and groups; and attempts to address the issues and differing perspectives of all the entities involved through mutually beneficial solutions.”

The State provides funding and program guidelines to support IRWM efforts throughout California. 

The Santa Clara Valley Water District participates in two IRWM efforts: the San Francisco Bay Area IRWM, and the Pajaro River Watershed IRWM.

The Bay Area IRWM is a nine-county effort, which includes northern Santa Clara County, to coordinate and improve water supply reliability, protect water quality, manage flood protection, maintain public health standards, protect habitat and watershed resources, and enhance the overall health of the bay.

The Pajaro River Watershed IRWM, which includes southern Santa Clara County, is a collaborative effort led by the district, San Benito County Water District, and Pajaro Valley Water Management Agency to improve water supply reliability, protect water quality, provide flood protection, and encourage environmental protection and enhancement.
