A great place to live!
Washington County lies on the east side of Minnesota. Its east border abuts the west border of the state of Wisconsin (across the St. Croix River). The Mississippi River flows south-southeastward west of Washington County, and forms the southwest border of the county as it flows toward its confluence with the St. Croix (at the county's southernmost point). Washington County terrain consists of low rolling hills, sloping to the south and east, with its highest point on the lower west border at 1,053' (321m) ASL. The county has a total area of 423 square miles (1,100 km2), of which 384 square miles (990 km2) is land and 38 square miles (98 km2) (9.1%) is water. It is the fourth-smallest county in Minnesota by land area and fifth-smallest by total area.
