The Chatsworth Nature Preserve is only open to the public one day a year in April to celebrate Earth Day. For several hours, we’re allowed to enter, go on guided hikes and visit vendor booths that include the Audubon Society, Neighborhood Council and other environmentally conscious groups in the San Fernando Valley The celebration is blessed during an opening ceremony by a Native American Indian from the Chumash – Tongva tribe, the original inhabitants of the area.
The reservoir opened in 1919 to provide irrigation water for what was then the largely agricultural West Valley. In 1969, DWP drained the reservoir for an enlargement project, but the basin was damaged in the 1971 Sylmar earthquake and never refilled.
Many people driving along Valley Circle Boulevard today don’t realize that the vast open property to the east behind a locked fence is a nature preserve. The large old dam remains in the southern portion – There should be some water there.
