Maintaining and protecting our watershed

About 29,000 acres of watershed lands in the East Bay provide needed protection for EBMUD’s high quality drinking water, while offering habitat for plants and animals – as well as a natural haven for the public to enjoy. These lands surround five reservoirs (Briones, San Pablo, Upper San Leandro, Chabot and Lafayette) and one basin that does not contain a reservoir (Pinole Valley).

The updated plan proposes changes to address issues that have arisen since the first plan was adopted in 1996, such as climate change, invasive mussels and toxic algae. It also incorporates plans for habitat conservation, grazing and fire protection, and proposes changes to allow access to specific watershed trails by cyclists. In addition, changes to the master plan seek to reduce the use of pesticides on the watershed.
