Artifacts made by early Native Americans in the Clear Lake Basin have been carbon-dated to 8,000 years ago, although tribal occupation probably extends back further in time.

[2] Faced with the onslaught on non-Indian settlers in their homelands, four Pomo groups, the Danoxa, Kaiyo-Matuku, Xowalek, and Yobotui, pooled their resources and purchased 90 acres (360,000 m2) of land in 1878 at Xabematolel.

[2] As part of its Termination and Relocation Policy in the interest of assimilating Natives into mainstream society, the US government passed the California Rancheria Act of 1953.

This law enabled the US to terminate relationships with the Habematolel Pomo and break up the lands of the Upper Lake Rancheria into individual allotments.

[4] In 2012, the Tribe entered into the online consumer financial services industry after approving a regulatory ordinance and establishing a separate arm of the Tribal government to regulate its e-commerce entities.

[9] The Tribe began initiating the proceedings to develop a casino on its trust land by first negotiating a Tribal-State Compact with the state of California.

On Memorial Day Weekend 2012, the Habematolel successfully opened Running Creek Casino, a full-service gaming destination in Upper Lake.

[12][13][14][15][16][17][18] California Congressman Mike Thompson named Habematolel Pomo of Upper Lake's Sherry Treppa as Woman of the Year in 2023.
