Welcome to the Minnesota River Basin Exhibit!


The MN River Basin Exhibit shows 335 miles of the river, all tributaries, and the 12 major watersheds. The river basin-which covers 16,770 sq. mi.-is made up of all or parts of 37 counties in MN, six counties in SD, and three in Iowa.

Eagles soared over the Minnesota River since it first formed 12,000 years ago when glacial Lake Agassiz drained through the River Warren. The warming climate changed the vegetation and the kinds of animals that lived in the area.
Wooly mammoths, musk oxen, and giant beavers died out, while bison, elk, and white tailed deer thrived. Today domestic animals like cattle, hogs, and horses dominate the landscape.
