Anza Map


Our Mission:

The Anza Ground Water Association will pursue opportunities that expand and share knowledge relating to the quality and quantity of our area groundwater on behalf of our community.

This Project is supported under a grant from the Department of Water Resources Local Groundwater Assistance program the help the Anza area develop the capacity to plan and manage their groundwater resources.  The map above was prepared by the USGS in its studies of the Anza Area's Groundwater.

Anza-Terwilliger Area Groundwater Management Planning Grant – Capacity Building

With the strong support of the Anza-Terwilliger Communities the County of Riverside received a grant from the State of California Department of Water Resources - Local Groundwater Assistance Fund. This grant will be used to begin a program to develop capacity for Groundwater Management, collect existing information, evaluate, and plan groundwater monitoring in the Anza-Terwilliger Area. Riverside County has contracted with South Coast Resource Conservation and Development Council and Integrated Planning and Management to collaboratively engage local, regional, federal and tribal stakeholders to participate in review and planning for future monitoring and management. Together through data collection, public outreach and workshops and stakeholder participation, they will assist the local area with efforts to plan, fund and develop a Groundwater Management Plan to assure the region has a sustainable future for all water users.

The first efforts will focus on setting up and holding workshops to engage stakeholder participation and to develop an understanding of the goals, organization and preliminary elements of agreement for cooperative groundwater management of the Anza-Terwilliger area.  In addition, collecting and consolidating existing groundwater monitoring data and identifying areas where additional groundwater data are needed will begin. The grant must produce its final report for approval in November which will contain an outline of the recommended Groundwater Management Plan.
