1992 Map of Picacho Reservoir

USGS Topo · Published 1995

About this map

Picacho Reservoir serves as a central hydrological landmark in Pinal County, where its spillway elevation of 1505 feet dictates the local water management landscape. This 1990s-era mapping reveals a complex network of desert irrigation and water transport, dominated by the massive Tucson Aqueduct and the Florence Casa Grande Canal. The intricate layout of canals, including the Santa Rosa Canal and the Central Main Canal, illustrates the engineered efforts to redirect water across the arid basin. Infrastructure like the Brady Pumping Plant and the Picacho Pumping Plant support this system, while local transit is anchored by routes such as Selma Hwy and Hanna Rd. The presence of several Check Gates and a Gaging Station further emphasizes the controlled nature of the water flow through the Florence Casa Grande Canal Extension during this period.
