Corral Hollow Creek
Corral Hollow Creek, originally El Arroyo de los Buenos Ayres (The Creek of the Good Winds), later Buenos Ayres Creek, is a stream and tributary of the San Joaquin River, flowing through Alameda County and San Joaquin County, Central California. Geography. The creek's headwaters are in the eastern slopes of the Diablo Range, and its confluence with the San Joaquin River is in the San Joaquin Valley. Course. Its source is in Corral Canyon, north of Mount Boardman in San Joaquin County. It then flows north 1.89 miles where it turns to flow west-northwest into  Alameda County and Corral Hollow, then turns abruptly east in the vicinity of Tesla to flow east, into San Joaquin County again, and another 2.5 miles to where it turns again in a northeasterly direction for to the Delta-Mendota Canal, south of Tracy, California, in the San Joaquin Valley. History. Named Arroyo de los Buenos Ayres or Aires by the Spanish, the creek retained this name despite the arrival of the Americans and the 49ers for some time. The name "Arroyo Buenos Ayres" appears on the Charles Drayton Gibbes' "Map of the Southern Mines" in 1852. However an 1857  map of California shows the canyon was now named Corral Hollow, but Buenos Aryes Creek, although anglicised, remained with its old name. By 1873 a State Geological Survey map indicated the name change was complete to Corral Hollow Creek.
