Corey Seppmann of Seppmann Well Drilling (left) and employee, Styles Johnson, monitor a test flow of water from the 300-foot-plus-deep well they had drilled on the west end of Minneopa State Park near the Seppmann Mill this week. The well will provide a water source for a bison herd that is expected to be introduced in the park next September. Seppmann's grandfather, Lewis Seppmann, built the nearby historic mill.
