Patwin has two (excl. Southern Patwin) or three (incl. Southern Patwin) dialects: "River Patwin (or Valley Patwin) was traditionally spoken along the Sacramento River in Colusa County ... Hill Patwin, was spoken in the plains and foothills to the west."[4][5]
Southern Patwin became extinct shortly after contact. It is very poorly attested, and may be a separate Southern Wintuan language (Mithun 1999).
As of 2012, the Tewe Kewe Cultural Center of the Yocha Dehe Wintun Nation has "a California Indian Library Collection and an extensive Patwin language and history research section."[6]
