Geography

Geographical location

Iowa is located in the Midwest of the USA. The state borders Minnesota to the north, Nebraska and South Dakota to the west, Missouri to the south, and Wisconsin and Illinois to the east.

The Mississippi River forms the eastern border of the state. In the west, river courses also form the state border - south of Sioux City it is the Missouri River, north of it the Big Sioux River. The topography of the state is characterized by rolling plains. Loess uplands are found along the western border, some several hundred feet thick. Among the few naturally formed lakes are the so-called Iowa Great Lakes - namely Big Spirit Lake, East Okoboji Lake, and West Okoboji Lake, among others. They are located in the northwestern part of the state, close to the Minnesota border.

Iowa's annual rainfall decreases toward the northwest. The more forested areas of the south and east transition to the tallgrass prairie of the Great Plains to the north and west.

The lowest point is the Mississippi River at Keokuk in southeastern Iowa (175 m); the highest point is Hawkeye Point (509 m). In relation to the area, the differences in altitude are small.

With a total area of 145,743 km², Iowa ranks 26th in the middle of all US states by area size. 1,042 km² (0.71 percent) of the state are water areas.
