Lake Anza is a manmade recreational swimming reservoir that’s part of Tilden Regional Park. The lake was created by building a small dam on Wildcat Creek back in 1938.
Though empty and serene on our sunny but cool early-April visit, Lake Anza bustles during hot summer months. The 10-acre lake has a little sunny, sandy beach on its west side (you can see it in the picture above) — so you can take a swim, soak up some rays and enjoy a homemade picnic or food from the lake’s snack bar. Nearby, there are hiking trails, BBQ pits and picnic tables.
Anza’s swim season is May through October, with lifeguards regularly on duty — see the current Lifeguard Service Schedule near the end of this page. During the normal season but when lifeguards are not on duty, swimming at your own risk is allowed within the roped-off area only. No swimming is allowed at all from November until the beginning of swim season.
EBMUD also tests the water quality regularly for bacteria, and posts the results online. You can see the current water test results here.
