About this map

The high Sierra Nevada landscape of Fresno County is defined here by the extensive hydroelectric infrastructure of the Florence Lake and Lake Thomas A Edison reservoirs. This 1983 survey illustrates a complex network of utility management within the Sierra National Forest, including the Vermilion Valley Dam, numerous gaging stations, and a series of diversion tunnels and siphons that redirect the South Fork San Joaquin River and its tributaries.
