1956 Map of Iris

USGS Topo · Published 1957

About this map

The Southern Pacific railroad corridor and a complex network of desert irrigation define this mid-century landscape in Imperial County. At the heart of the grid is the settlement of Iris, positioned where the rail line intersects the transition between the agricultural lowlands and the arid Mesa. The infrastructure shown here is a critical study in 1950s water management, featuring the massive Coachella Canal and East Highline Canal, supported by a dense alphabetized system of drains and laterals such as Q Drain and L Lateral.
