Big Creek is a stream in southern Madison and northeastern Wayne counties the U.S. state of Missouri. It is a tributary of the Castor River.[1]
The stream headwaters are at the confluence of the East Fork Big Creek and Middle Fork Big Creek just south of Buckhorn in Madison County at 37.3342°N -90.2931°W. The stream flows southeast parallel to Missouri Route M into Wayne County. The stream flows past the communities of Cascade and Gravelton where it turns easterly to enter the Castor River one half mile from the Wayne-Bollinger county line at 37.2897°N -90.2275°W.[1] [2]
Big Creek was named so because it is large relative to other nearby creeks.[3]
