1965 Map of Trimmer

About this map

The Watts valley and the rising foothills of the Sierra National Forest define this mid-1960s landscape in Fresno County. This area sits at the intersection of foothill agriculture and the hydroelectric development of the Kings River. The map is particularly notable for its bathymetric data, showing 100-foot underwater contours for the Pine Flat Lake reservoir. These contours were derived from 1948 aerial photography, capturing the topography of the river canyon prior to its inundation by the Kings River dam projects. This provides a rare look at the original canyon floor and riverbank terrain now submerged beneath the lake's surface.
