What happened

The episode as NWS FGF wrote it up.

The Maple River at Mapleton crested around 908.8 feet MSL on June 15th. Major flooding occurs at this point when the river stage rises above 907 feet MSL. The Maple River was reported to be one-quarter to one mile wide in spots. The flooding river cut off the access road to the Maple River Golf Course, which shut down the course. Many holes on the golf course were flooded.
