The Pomo people are Indigenous to northern California and formed about 21 autonomous communities, speaking seven Pomoan languages.

The tribe's reservation is the Dry Creek Rancheria, situated near the town of Geyserville in Sonoma County, California.

Much of the original reservation lands were inundated by the waters of Lake Sonoma after the construction of the Warm Springs Dam.

Members of the tribe, without notice, attempted to recall and replace the government (Tribal Board of Directors).
