About this map

The eastern shore of the Salton Sea dominates this 1990s landscape, revealing a highly engineered environment where desert ecology meets large-scale irrigation and military operations. The Imperial State Wildlife Area (Wister Unit) occupies a significant portion of the shoreline, managed through a complex network of water controls including Niland Lateral 1 and Niland Lateral 5. This irrigation infrastructure is essential for maintaining the habitat in a region where the elevation sits more than 200 feet below sea level.

Rising to the east, the East Mesa transitions into the Chocolate Mountain Aerial Gunnery Range, a vast military reservation. The Coachella Canal serves as a critical boundary between the irrigated lowlands and the higher desert terrain. Traces of local history and transport are found in the settlement of Wister and the path of the Old Niland Road, while the numerous siphons, levees, and dikes illustrate the continuous effort to manage water flow across this unique California basin.
