Alkali Lake is thought to have reached a prehistoric maximum depth of 270.7 feet (82.5 meters) and covered about 1448.4 square miles (2,331 square kilometers). Since then, its water level has varied, with a drying trend. Notable features include dissolved alkaline salts averaging 10% of total brine weight in its seasonal waters and a nearby chemical disaster, Alkali Lake Chemical Waste Dump.
