Lion Creek Watershed
The 3.5-square-mile Lion Creek Watershed lies in the city of Oakland. The watershed begins on the west side of the Oakland hills and runs west to San Francisco Bay, narrowing as it passes through flatter land. The eastern boundary of the watershed roughly follows Skyline Boulevard where it borders the San Leandro Creek Watershed. The watershed includes three creeks: Chimes, Horseshoe, and Lion. The former Leona tributary, now part of Lion Creek, drains an abandoned sulfur mine. Horseshoe and Chimes creeks both discharge into Lion Creek, which empties into Lake Aliso on the Mills College campus. From there the creek enters a series of engineered channels and underground culverts that continue to San Leandro Bay within the larger San Francisco Bay.
