The Salton Sink is the low point of an endorheic basin, a closed drainage system with no outflows to other bodies of water, in the Colorado Desert sub-region of the Sonoran Desert. The sink falls within the larger Salton Trough and separates the Coachella Valley from the Imperial Valley, which are also segments of the Salton Trough. The lowest point of the sink is 269 ft (82 m) below sea level, and since 1906 the 343-square-mile (890 km2) Salton Sea has filled the lowest portion of the sink to a water depth of up to 43 ft (13 m).
