# Alkali Lake (Oregon)

Alkali Lake is a geographic sink in Lake County, Oregon, United States. It is in the Alkali Subbasin of the Summer Lake Basin watershed in southeastern Oregon, located 26 miles east of Christmas Valley, Oregon, northeast of Lake Abert, to the immediate west of Abert Rim and Highway 395.

Alkali Lake is thought to have reached a prehistoric maximum depth of 270.7 feet (82.5 meters) and covered about 1,448.4 square miles (3,751 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.
