The Elem Indian Colony reservation was originally formed under the name Sulfur Bank Rancheria (39°00′31″N 122°40′13″W / 39.00861°N 122.67028°W) in 1949. The reservation lies between Clearlake Oaks to its north, and Clearlake to its south.
The tribe was organized in 1936 and has a population of about 100[when?]. Currently[when?] they are attempting to regain ownership of Rattlesnake Island near their reservation, where they had held ceremonies for centuries.
The colony is served by the Konocti Unified School District.
