The Wildcat Creek watershed drains . The creek originates on Vollmer Peak in Tilden Regional Park just east of the city of Berkeley. It feeds the artificial Lake Anza (constructed in 1938) as well as the smaller reservoir Jewel Lake (constructed in 1921) along its course. In its lower course, it passes through the city of San Pablo and portions of the city of Richmond. Where it exits the hills, it passes through Alvarado Park, which includes a WPA-constructed stone arch bridge over the creek. It also courses through San Pablo's civic center and Davis Park. Wildcat Creek culminates in the Wildcat Marsh and thence to San Pablo Bay.
