Isle du Bois Creek is a stream in Jefferson and Ste. Genevieve counties of the U.S. state of Missouri. It is a tributary of the Mississippi River.[1]
The stream headwaters arise at 38.09°N -90.3408°W in southern Jefferson County and it flows to the east-northeast for approximately one-half mile. At this point it becomes the boundary between the two counties and meanders to the east and northeast. The stream passes under I-55 and US Route 61 approximately 1.5 miles south of the community of Danby. The stream continues on to the east-northeast to its confluence with the Mississippi at the south end of Rush Island at 38.1003°N -90.2322°W.[1]
Isle du Bois is a name derived from the French denoting "isle of the woods".[2]
