About this map

The western shoreline of the Salton Sea dominates this mid-century survey, revealing a landscape defined by water management and military activity. At this time, the water level was recorded at Elevation 235 Feet Below Sea Level, a measurement that dictates the surrounding environment of Sand Dunes and marshes within the Salton Sea National Wildlife Refuge. The map details the complex irrigation infrastructure feeding into the basin from the south, including the Trifolium Extension, Trifolium Drain, and various laterals like Lateral 9.

Small coastal settlements such as Mitchell and Clancy appear alongside industrial and military landmarks. The presence of the Salton Sea Test Base and its accompanying Landing Strip highlights the area's strategic importance during the Cold War. Drainage from San Felipe Creek and San Felipe Wash creates a delta-like transition into the sea, where a Gaging Station and series of Levee systems monitor and control the precarious desert hydrology.
