Serrano Creek
Serrano Creek is a roughly tributary of San Diego Creek in the U.S. state of California. The creek starts in the Santa [Ana Mountains] in a canyon in Whiting Ranch [Wilderness Park], near the boundary of the Cleveland [National Forest]. It then flows southwest into the city of Lake Forest, running in a channelized course roughly parallel to Aliso Creek. It abruptly turns northwest then southwest at 90-degree angles as it enters a large storm drain that takes it the rest of the way to the confluence with the La Cañada Channel, creating the main stem of San Diego Creek.
