San Timoteo Watershed

San Timoteo Watershed Management Authority

The San Timoteo Watershed Management Authority (STWMA) was formed by the City of Beaumont, Beaumont Cherry Valley Water District, South Mesa Water Company, and Yucaipa Valley Water District in 2001. The STWMA monitors the groundwater quality and groundwater levels in the regions known as the Beaumont and San Timoteo Management Zones.

Wildermuth Environmental, Inc. (WEI) conducted an investigation which included a two-year field program, development and application of modeling tools to characterize future surface water quality problems and to analyze solutions, and the development of a two-prong stormwater and dry-weather discharge management strategy.

This urban runoff management strategy is an integral component of the Integrated Regional Water Management Program (IRWMP), which is currently being implemented by the STWMA members. It provides the strategy and facilities necessary to accomplish the second Program Element of the IRWMP; to develop and implement a comprehensive surface water resources management and recharge program. The STWMA area stakeholders are committed to meeting the IRWMP goals in order to enhance the basin water supplies, protecting and enhancing water quality, optimizing the management of the STWMA area groundwater basins, protecting and enhancing habitat in the STWMA area, and equitably distributing the benefits and costs of the IRWMP. The urban runoff management strategy accomplishes the IRWMP goals by integrating stormwater management, water quality protection and enhancement, supplemental water recharge, water supply reliability, and groundwater management strategies with flood control, public access, and recreation management strategies. Measurable components of its success will include increases in local yield, increases in recharge capacity, the maintenance and enhancement of water quality, and the demonstration that the Basin Plan maximum benefit objectives are being met.
