What happened

The episode as NWS GRB wrote it up.

The flooding that occurred in early April was a carryover from the excessive precipitation that fell in late March. Four locations along 3 rivers exceeded flood stage during April. Duck Creek in Howard (Brown co.) reached 17.85 feet, just above flood stage, on April 1. The Menominee River at McAllister reached 15.79 feet on the 1st, slightly above the 15 foot flood stage. The Wolf River at Shiocton (Outagamie co.) and New London (Outagamie and Waupaca counties) also exceeded flood stage. Shiocton reached 10.83 feet (estimate) and New London peaked at 9.38 feet, both on April 5.The only significant inconvenience from the floods occurred along the Wolf River. In New London, a few local roads were flooded and closed for a couple of days. The city park along the banks of the river was also flooded. In Shiocton, homes near the river were surrounded by water and the city park adjacent to the river was flooded throughout the event.
