Traditionally, the tribe spoke the Wintun/Patwin language, a Wintuan language of the Penutian language family. The Colusa Indian Community Council published a language book and are working on language CDs and DVDs to help foster language preservation.
The traditional language spoken by Wintun (Patwin) people was not Wintu, but Patwin or Wintun. Wintu was a Penutian language spoken by the Wintu people of lands north of Cottonwood Creek in the area of Redding, California. 
The tribe owns and operates the Colusa Casino Resort, Seasons Buffet, Wintun Dinnerhouse, and Jack's Lounge, all located in Colusa.
The Cachil Dehe Band of Wintun Indians, with 45 original members, ratified their constitution and by-laws on November 23, 1941. In 1969 the tribe built a traditional roundhouse and refurbished it in 1993.ɨI was present during construction of the new roundhouse in 1977, not 1969. Ira Heinrich
