About the map
This map shows major rivers, reservoirs and lakes of Iowa like Des Moines River, Iowa River and Rathbun Lake. In general, rivers in Iowa flow into the Gulf of Mexico.
Lake Red Rock, Big Spirit Lake and Rathbun Lake are the largest lakes in Iowa. All three lakes exceed 10,000 acres in area.
Iowa is a bit unique because rivers delineate its west and east boundary. On the west of Iowa, it’s the Missouri River that borders South Dakota and Nebraska. Then, on the east side of Iowa, it’s the Mississippi River that marks its border with Illinois and Wisconsin. Des Moines River is another key watercourse because it flows through the capital city – as shown in this map of Des Moines.
