Laguna Creek watershed

The Laguna Creek watershed consists of 25.1 square miles (100 km²) of land within northern California's Alameda County. The watershed drains the foothills of the Diablo Range south of Niles Canyon. To the southeast, the area of Mission Peak Regional Preserve around Mission Peak is included. Agua Caliente, Canada del Aliso, Mission, Morrison, Sabercat, Vargas, and Washington creeks drain the area of the watershed. They drain into Laguna Creek and eventually Mud Slough.

Water from winter and spring storms feed the creeks and the watershed. Natural springs along Mission Peak are also a source of water. Many of the creeks are dry when there is no rain.
