## Geography

[edit | edit source]

The Missouri River flows southward along the county's west boundary line. Swan Creek flows west-northwest through the county's SW corner, discharging into the Missouri. The county's terrain consists of semi-arid rolling hills, carved by drainages and gullies. Most of the area is devoted to agriculture.[5] The terrain slopes to the south and east, although the western portion of the county drops westward into the Missouri River valley. The county's highest point is on the eastern portion of its north boundary line, at 1,982' (604m) ASL.[6] The county has a total area of 745 square miles (1,930 km2), of which 709 square miles (1,840 km2) is land and 36 square miles (93 km2) (4.8%) is water.[7]
