Westside-San Joaquin Integrated Regional Water Management Plan

The City of Patterson is listed as a stakeholder in the collaborative effort to manage all aspects of water resources within our region. IRWM crosses jurisdictional, watershed, and political boundaries. It 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 2019 Westside-San Joaquin IRWMP was submitted to the Department of Water Resources on January 4, 2019 and is still pending approval. If you would like to view the current report, please click on the following link:
