About this map

Picacho Reservoir dominates this landscape in Pinal County, serving as a critical hydraulic point in the desert irrigation system. The 2011 survey documents the reservoir's footprint and the associated Picacho Reservoir Dam, which controls the water levels for the surrounding agricultural tracts. To the southeast, the terrain begins to rise into the Picacho Mountains, creating a sharp contrast between the flat, gridded basin and the natural desert uplands.

The human footprint is defined by a rigid grid of rural routes, including Selma Hwy and S Brady Pump Rd, which segment the land into large parcels. This road network, featuring names like North Star Rd and E Battaglia Dr, reflects the systematic development of the area's water-dependent economy. The map provides a clear look at the intersection of engineered water management and desert geography at the start of the 2010s.
