 The majority of present-day North Richmond was territory of the Karkin tribe (or "Carquinez") however the land lies on what was a border area with the Chocheño tribe and likely had influences of both groups.The tribes made great use of the salmon and trout runs on the rivers.However, today, culverting and damming has decimated the habitat for these species and they are rarely present ever at the opening of the watercourse.
