Integrated Regional Water Management (IRWM) is a comprehensive and collaborative approach to managing water resources on a regional scale. 

The practice of IRWM is rooted in the principle of regional control, enabling self-identified regions to implement water management solutions that increase regional self-reliance, reduce conflict, and manage water to concurrently achieve social, environmental, and economic objectives.

The San Gorgonio Pass area is the mountain pass between the San Bernardino Mountains to the north and San Jacinto Mountains to the south. Water management within the San Gorgonio Region has historically been conducted by individual water resource agencies or together as part of specific groups to address specific needs. The San Gorgonio Regional Water Management Group (RWMG) was formed in 2016 by a group of stakeholders within the San Gorgonio Pass with an interest in collaborating to identify regional water resources needs and implement the strategies and projects necessary to meet those needs.

The San Gorgonio IRWM Region was formed in 2016 through a Regional Acceptance Process application to the California Department of Water Resources. The San Gorgonio IRWM Region’s first IRWM Plan is currently being developed through a collaborative stakeholder process to set regional goals and to create an integrated planning process that develops strategies and projects to address the water resource management needs of the Region’s stakeholders.


Regional Water Management Group

In 2016, the San Gorgonio IRWM Regional Water Management Group (RWMG) was formed to manage the development of a new IRWM Region in the San Gorgonio Pass. The RWMG includes the City of Banning, Banning Heights Mutual Water Company, Cabazon Water District, High Valleys Water District, Riverside County Flood Control and Water Conservation District, and the San Gorgonio Pass Water Agency. The RWMG is responsible for preparing the IRWM Plan and governing the planning process, as well as approving projects for inclusion in the Plan.

Stakeholder Participation

The Stakeholder Advisory Committee (SAC) was created to provide an opportunity for key stakeholders to participate in the SG IRWM Program. SAC members are selected by consensus and serve on behalf of the RWMG to inform and advise the RWMG agencies on regional needs, goals, priorities, strategies, and projects. Together, SAC members represent local and countywide agencies, tribal nations, commercial, community, and industry groups involved in water resource management.

The main opportunity for public participation in the San Gorgonio IRWM program is through SAC meetings and workshops. All meetings are open to the public and there are no limitations preventing the public and other stakeholders and the public from participating on an equal footing with members of the SAC.



All interested stakeholders and members of the pubic are invited to participate in all public meetings of the Stakeholder Advisory Committee. The current meeting schedule is provided below.

Project submittal is a dynamic and on-going process to allow for new and updated projects to be readily incorporated into the IRWM Plan. Projects can be submitted at any time or through the Call-for-Projects. Projects can be Implementation or Conceptual projects. Implementation projects are those that meet IRWM Plan requirements and will benefit the Region. Conceptual projects are those through further development will meet the IRWM Plan requirements and could potentially benefit the region. 

Use the Project Nomination Form (PNF) to submit your project, which clearly identifies information required for Implementation or Conceptual projects. The PNF is updated periodically and is posted here. Instructions for submitting are included on the PNF. 




The California Department of Water Resources (DWR) released the final version of the Project Solicitation Package in April 2019.  Each Funding Area in the State will have its own deadline for turning in grant applications.  The Colorado River Funding Area, of which the San Gorgonio IRWM Region is a part of, is anticipated to have a deadline to submit pre-application materials for Round 1 Funding by late July 2019.

Each Region must submit a single application, with one or multiple projects.  Projects that are ready for implementation can be nominated to be included in the San Gorgonio IRWM Region's application for Round 1 funding by filling out the Project Information Form (PIF) found on DWR's Implementation Grant Program website:

The PIF should then be emailed to by July 8th, no later than 5:00 p.m.

Projects that have been previously nominated and adopted as part of the San Gorgonio Region's IRWM Plan are eligible to be included in the grant application.  Any new projects that are not currently in the Plan will be reviewed on a case-by-case basis and could be incorporated into the Plan and grant application or could be placed on a list for inclusion in future grant applications.
