The Integrated Regional Water Management Plan (IRWMP) is a document that identifies and plans for the water resource-related needs
of the Upper Santa Clara River Watershed. The IRWMP examines current and future water-related needs, identifies regional objectives
for water-related resource management, develops strategies to address identified needs and then evaluates and offers various projects
to meet the regional objectives. The purpose of the IRWMP is to integrate planning and implementation efforts and facilitate regional
cooperation, with the goals of reducing water demands, improving operational efficiency, increasing water supply, improving water quality,
and promoting resource stewardship over the long term. A collaborative stakeholder-driven process was used to develop the IRWMP.
The IRWMP effort was funded entirely by local participating agencies.
The IRWMP has been updated to conform to the Proposition 84 guidelines, which also included a climate change technical study. The 2014 Update of the IRWMP is now complete and you can view the documents by clicking here. Additionally, a salt/nutrient management plan is also being prepared (see below for details).
The Regional Water Management Group for the IRWMP has formed a cooperative to prepare a Salt Nutrient Management Plan (SNMP) for the Santa Clara River Valley East Ground Water Subbasin to comply with the State's Recycled Water Policy.
The report is being prepared using guidance set forth by the Los Angeles Regional Water Quality Control Board and presents an evaluation of the salt and nutrients, and current and proposed water resource management practices in the Santa Clarita Valley. Draft chapters of the SNMP can be found on Documents page.
SNMP Taskforce meetings are held at the Newhall County Water District, 23780 North Pine Street, Newhall, CA 91321. For more information please contact Cathy Z. Hollomon at (661) 297-1600 Extension 282.
