1965 Map of Picacho Reservoir

About this map

Picacho Reservoir dominates this Pinal County landscape, serving as a critical node for water management in the mid-1960s. Fed by the Florence Canal, the reservoir features a notable Spillway Elev 1505 and connects to an intricate irrigation network including the Casa Grande Canal and its Extension. This system illustrates the mid-century engineering efforts to support agriculture in the arid Arizona basin. To the southeast, the terrain rises sharply into the Picacho Mountains, where the elevation reaches over 3,300 feet. The transition from the engineered flats of the reservoir basin to the steep slopes of the mountains is marked by a network of unimproved routes and a Jeep Trail, reflecting the desert's accessibility at the time. Local travel was facilitated by rural arteries such as Cornman Road and Houser Road, which cut through the survey's western half.
