Located in Southeast Minnesota and Northeast Iowa, the Upper
Iowa 8-Digit Hydrologic Unit Code (HUC) subbasin lies within the Driftless area
and Western Corn Belt Plains Ecoregions of both States.
The watershed is home to the last known native Brook Trout
population in Iowa, boasts 11 streams with evidence of natural trout
reproduction, contains nearly 30 percent of Iowa’s coldwater streams, and has
extensive cave networks, including the National Natural Landmark Coldwater Cave.
Approximately ninety eight percent of the 640,812 acres in this
HUC are privately owned. The remaining acres are state, federal or county lands
or covered by open water. Assessment estimates indicate 1,943 farms in the
watershed. Approximately thirty eight percent of the operations are less than
180 acres in size, fifty five percent are from 180 to 1000 acres in size, and
the remaining farms are greater than 1000 acres in size.
The main resource concerns in the watershed are sediment and
erosion control, stormwater management, drinking and source water protection,
animal waste management, nutrient management and wetland management.
