1977 Map of Clearlake Highlands

USGS Topo · Published 1980

About this map

Clear Lake dominates the upper half of this 1977 orthophotograph, its deep waters and irregular shoreline defining the geography of the surrounding Lake County landscape. On the eastern shore, the residential and commercial patterns of Clearlake Highlands are clearly visible, showcasing the community's development during the late 1970s. This aerial-based survey provides a unique visual record of the land beyond the primary lake, including the smaller, landlocked Borax Lake to the north and the distinct basin of Thurston Lake to the south. The transition from the dense street grids near the waterfront to the orchards and undeveloped terrain further inland illustrates the area's growth and its reliance on the water's edge for settlement. For those studying California's largest natural freshwater lake, this document captures the exact footprint of the peninsula and the adjacent highlands at a moment of significant local expansion.
