Elem Indian Colony

The Elem Indian Colony of Pomo Indians (also known as the Elem Band of Pomo and Sulfur Bank Band of Pomo Indians) are a Native American band of Pomo based on 50 acres (200,000 m²) near Clearlake Oaks, California on the Eastern shore of Clear Lake. The Elem Indian Colony reservation was originally formed under the name Sulfur Bank Rancheria (39°00′31″N 122°40′13″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. Currently they are attempting to regain ownership of Rattlesnake Island near their reservation, where they had held ceremonies for centuries.
