Gravois Creek is a stream in south central Morgan County, Missouri. [1] It is a tributary of the Osage River within the Lake of the Ozarks. [2]
The stream headwaters arise along the east side of Missouri Route 135 approximately 3.5 miles south of Stover [2] at 38°23′26″N 92°59′28″W / 38.39056°N 92.99111°W [1] at an elevation of approximately 1100 feet. [3] The stream flows east to southeast passing under Missouri Route 5 to enter the waters of the Lake of the Ozarks at Gravois Mills [2] at 38°19′13″N 92°49′38″W / 38.32028°N 92.82722°W and an elevation of 663 feet. [1] Prior to the impoundment of the lake the stream confluence with the Osage River was at approximately 38°13′16″N 92°44′10″W / 38.22111°N 92.73611°W and an elevation of 490 feet (150 m) on the Morgan- Camden county line approximately eight miles southeast of Gravois Mills.

The stream was named for the large quantity of gravel in its streambed from the French "gravois" rubbish or gravel. [5]
