The Floyd River rises in northwestern O'Brien County near the town of Sanborn and flows generally southwestwardly through Sioux, Plymouth and Woodbury Counties, past the towns of Sheldon, Hospers, Alton, Le Mars and Merill. At Merrill the Floyd collects its largest tributary, the West Branch Floyd River, which is about 40 mi (65 km) long. The West Branch rises near Boyden in northeastern Sioux County and flows generally southward into Plymouth County, past Maurice and Struble. The Floyd enters Woodbury County near the Leeds neighborhood of Sioux City.
The Floyd River has come out of its banks on several occasions, causing distastrous flooding in Sioux City in
1892 and1953 . The river has since been the focus of an intensiveflood control project. The Floyd's lower channel through Sioux City has been straightened, channelized, lined withriprap and banked by a high earthenlevee .The Floyd River is the site of frequent fish kills caused by runoff of massive amounts of animal waste from farm feedlots into the river.fact|date=May 2007
