Arroyo Seco (Alameda County)
From Wikipedia, the free encyclopedia
Arroyo Seco is a watercourse in Alameda County, California which traverses through the city of Livermore. Arroyo Seco means dry stream in Spanish. Arroyo Seco lies above the Arroyo Seco watershed, which includes the eastern part of the city of Livermore and also the Lawrence Livermore National Laboratory. The Mocho Subbasin is the largest of the subbasins in the Livermore Valley watershed. This subbasin is bounded to the west by the Livermore Fault Zone and to the east by the Tesla Fault. Some groundwater flow occurs across these fault boundaries, but flows are discontinuous below a depth of fifty feet across the Tesla Fault and south of the Arroyo Mocho channel across the Livermore Fault.[1] A number of threatened and endangered species occur in this watershed.[2]
