Stege Marsh, also known as theSouth Richmond Marshes,[1] is a tidal marshland wetlands area inRichmond, California in westernContra Costa County.[2]
The marsh is the delta at the mouth ofBaxter or Stege Creek, which drains from a watershed extending into theBerkeley Hills inEl Cerrito. The marsh is oppositeMeeker Slough from whereMeeker Slough Creek drains intoCampus Bay, which is a part of theRichmond Inner Harbor of theSan Francisco Bay.
