The Alkali Lake Indian Band, also known as the Esketemc First Nation, is a First Nations government of the Secwepemc (Shuswap) people, located at Alkali Lake in the Cariboo region of the Central Interior of the Canadian province of British Columbia. It was created when the government of the then-Colony of British Columbia established an Indian Reserve system in the 1860s. It is one of three Secwepemc bands that is not a member of either the Shuswap Nation Tribal Council or the Northern Shuswap Tribal Council.
In the Shuswap language, the people of Alkali Lake are the Esketemc ("people of Esket").
Indian Reserves under the administration of the Esketemc First Nation are:
In Canada, an Indian band or band, sometimes styled as a First Nation band or simply a First Nation, is the basic unit of government for those peoples subject to the Indian Act (i.e. Status Indians or First Nations). Bands are typically small groups of people: the largest in the country, the Six Nations of the Grand River First Nation had 22,294 members in September 2005, and many have a membership below 100 persons. Each First Nation is typically represented by a band council chaired by an elected chief, and sometimes also a hereditary chief. As of 2013 there were 614 bands in Canada. Membership in a band is controlled in one of two ways: for most bands, membership is obtained by becoming listed on the Indian Register maintained by the government. As of 2013 there were 253 First Nations which had their own membership criteria, so that not all Status Indians are members of a band.
A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality (in other words, a pH value above 7, typically between 9 - 12). They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity. In addition, many soda lakes also contain high concentrations of sodium chloride and other dissolved salts, making them saline- or hypersaline lakes as well. High pH and salinity often coincide, because of how soda lakes develop (see "Geology, geochemistry and genesis"). The resulting hypersaline and highly alkalic soda lakes are considered some of the most extreme aquatic environments on Earth.
In spite of their apparent inhospitability, soda lakes are often highly productive ecosystems, compared to their (pH-neutral) freshwater counterparts. Gross primary production (photosynthesis) rates above 10 g C m−2 day−1 (grams carbon per square meter per day), over 16 times the global average for lakes and streams (0.6 g C m−2 day−1), have been measured. This makes them the most productive aquatic environments on Earth. An important reason for the high productivity is the virtually unlimited availability of dissolved carbon dioxide.

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 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.
Plants known to occur in the dunes immediately north of the lake include:
