Originates way up in Montclair. Flows into Temescal Lake, where it's joined by the branch from the Tunnel Road area (which also drains the BART tunnel). From there it's culverted under Highway 24. The Grandview Branch (also called Vicente Creek) drains the Claremont Heights area and joins the culvert near Chabot School. A religious college has a nice open creek segment in its large back yard. Harwood Creek (a.k.a. Claremont Creek) joins in from the north. Below there it's culverted to the outflow in Emeryville, except for one peculiarity: a fake creek segment near Claremont and Telegraph, where part of the flow is diverted above-ground.
