form the Fabius River in northeastern Marion County. The natural confluence of the rivers was about upstream of the Fabius River's mouth at the Mississippi River, but the North Fabius River has been re-routed by channelization, and now joins the South Fabius River about upstream of the Mississippi. The Fabius flows into the Mississippi River about three miles downstream of Quincy, Illinois. The Fabius River averages approximately 907 cubic feet per second at the junction of the North and South Fabius rivers. This discharge is obtained by combining the discharges of the North and South forks,(see above), since the Fabius has never been measured by the USGS.
