The Antelope Valley Watershed is geographically unique since it does not outlet to the Pacific Ocean. The watershed straddles the Los Angeles-Kern County Line and encompasses approximately 1,200 square miles within Los Angeles County. Numerous streams originating in the mountains and foothills flow across the valley floor and eventually pond in the dry lakes (Edwards Air Force Base) adjacent to the Northern County line. The valley lacks defined natural and improved channels outside of the foothills and is subject to unpredictable sheet flow patterns.
Existing constraints include the LACFCD not serving the portion of the County north of Avenue S. Existing efforts include the Antelope Valley Integrated Regional Water Management Plan which aims to develop project concepts for areas within and outside the LACFCD boundaries, continuing to seek funding sources for the entire Region, and ultimately implementing all facilities identified in the Antelope Valley Comprehensive Plan of Flood Control and Water Conservation.
