Fluvius Innominatus (Latin for "unnamed river") or Central Creek^[1] is a stream in Richmond and El Cerrito, California, in western Contra Costa County. There is one main source and a secondary unnamed tributary. The creek drains into Hoffman Marsh and then flows into the bay through Point Isabel Regional Shoreline's Hoffman Channel.^[2] However, before the area was developed and as early as 1899 the creek had as many as 11 sources which stretched far higher into the Berkeley Hills.^[3]
