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 m) 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 in 1949. 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.'
