 At this point the channel becomes better defined and also deep enough for kayaking during the winter months.Kayakers access the creek here by means of an unpaved boat launch road that is reachable from Marsh Road.The lower reach of the creek flows westward past the small community of Bloomfield, paralleling Valley Ford Road, and passes under State Route 1, known locally as "Highway 1" or "the Shoreline Highway", at which point it begins to define the Sonoma-Marin county line.
