About the little sioux river


The Little Sioux River flows through Iowa, Minnesota, and South Dakota, covering a length of approximately 250 miles. The river is named after the Sioux Native American tribe, who were the primary inhabitants of the area. The river is a tributary of the Missouri River and is crucial for the agricultural industry in the region, providing irrigation water for crops such as corn and soybeans. The river is also home to several species of fish, including walleye, catfish, and smallmouth bass. The river is impounded by several dams, including the Saylorville Dam and the Little Sioux Dam, which provide flood control and hydroelectric power. There are also several recreational opportunities along the river, including camping, fishing, and canoeing.
