Dominguez Watershed


The Dominguez Watershed is located within the southern portion of Los Angeles County, California, and encompasses approximately 133 square miles of land and water. Approximately 81 percent of the watershed or 93 percent of the land is developed. Residential development covers nearly 40 percent of the watershed, and another 41 percent is made up by industrial, commercial and transportation uses. With a population of nearly 1 million, considerable demands are made on infrastructure and services within the watershed. Water supply is limited and the majority of water use is from imported sources. Parkland and open space are in short supply and generally are deficient.

Existing efforts to address the constraints of the watershed are included in the Dominguez Watershed Management Master Plan (DWMMP). The DWMMP was developed by the Dominguez Watershed Advisory Council (DWAC) which consisted of local governmental representatives, environmental groups, regulating agencies, members of business and industry, water and sewer service providers and private citizens.

The DWMMP can be used to assist in the development of project concepts for the Dominguez Watershed to protect and enhance water quality, conserve, reuse and recharge water supply, protect, enhance and restore native habitats and biological resources and to promote public awareness and involvement. The DWAC continues to meet on a quarterly basis to promote and implement the principals and practices of the DWMMP.
