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,[1] located 26 miles east of Christmas Valley, Oregon, northeast of Lake Abert,[2] 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 1448.4 square miles (2,331 square kilometers). Since then, its water level has varied, with a drying trend.[1] Notable features include dissolved alkaline salts averaging 10% of total brine weight[2] in its seasonal waters and a nearby chemical disaster, Alkali Lake Chemical Waste Dump.

Plants[edit]

Plants known to occur in the dunes immediately north of the lake include:[3]

Climate[edit]

According to the Köppen Climate Classification system, Alkali Lake has a steppe climate, abbreviated "BSk" on climate maps.
