Lafayette Reservoir is a 925-acre recreation area managed by the East Bay Municipal Utility District, featuring a 125-acre man-made lake. The reservoir serves as an emergency water storage facility for the surrounding East Bay communities. Visitors can access over 30 miles of hiking trails that traverse the hilly terrain surrounding the water. Fishing is permitted for species including rainbow trout, largemouth bass, and catfish. The facility offers boat rentals, including pedal boats, rowboats, and electric motorboats, with private watercraft prohibited to prevent invasive species. A paved 2.7-mile trail circles the reservoir, providing a relatively flat path for walkers and joggers. Picnic areas are equipped with tables and barbecue facilities available on a first-come, first-served basis or via reservation. The site is designated as a wildlife habitat, home to deer, coyotes, and various raptor species.
