1965 Map of Picacho Reservoir

USGS Topo · Published 1977

About this map

Picacho Reservoir dominates this 1960s desert landscape, its waters controlled at Spillway Elev 1505 to support regional irrigation. The irrigation network is clearly defined by the Casa Grande Canal and the Florence Extension, which channel water across the arid flats toward agricultural fields beyond the map's edge. This infrastructure highlights the era's intensive water management efforts in Pinal County.
