Spring Valley serves as a central point of reference in this corner of Lake County, where the landscape transitions from the protected boundaries of the Mendocino National Forest to the waters of the Indian Valley Reservoir. The terrain is defined by a complex network of drainage basins including North Fork Cache Creek and Wolf Cr, which carve through dozens of named canyons such as Benmore Canyon and Kattenburg Canyon. This 2018 survey reveals a topography heavily influenced by both natural erosion and modern water management.
