About this map

Owens Valley landscape dynamics are centered on the sophisticated water management infrastructure of the early 21st century. The Los Angeles Aqueduct cuts a prominent diagonal across the terrain, supported by a network of local irrigation and drainage systems including the Aberdeen Ditch, Aberdeen Bypass Ditch, and Blackrock Drain. This hydraulic engineering exists alongside the natural hydrology of the Owens River and several significant spring sites like Blackrock Springs and Little Blackrock Spring.

To the east, the map climbs into the White-Inyo Range and the Inyo National Forest, where features like Crystal Ridge overlook the valley floor. The settlement of Aberdeen sits at the northern edge of this study area, near the marshy grounds of Hines Slough and Calvert Lake. This map captures a complex environment where industrial-scale water transport intersects with native riparian habitats like the Tulare Swamp.
