Geography

Fillmore County is on Minnesota's border with Iowa. The Root River drains the county, flowing eastward. The North Branch and the Middle Branch combine east of Shady Creek, while the South Branch meets their combined flow at Preston. Bear Creek drains the lower part of the county, discharging into the Root in the eastern part of the county. Willow Creek also drains a portion of the lower county, discharging into the Root at Preston. The Upper Iowa River flows eastward, mostly in adjoining Iowa counties, but briefly enters Fillmore County near the midpoint of its southern border.

The county's terrain consists of rolling hills, carved by gullies and drainages, with the available area dedicated to agriculture.^[6] The terrain slopes to the east; its highest point is on the lower western border, at 1,378 ft (420 m) ASL.^[7] The county has a total area of 862 square miles (2,230 km²), of which 861 square miles (2,230 km²) is land and 0.8 square miles (2.1 km²) (0.09%) is water.^[8]
