What happened

The episode as NWS FSD wrote it up.

Snowmelt resultant flooding from April continued through May and into June along the very slowly draining James River in South Dakota. While flood levels continued to decrease from their crest in April, minor flooding persisted into June in some locations, slowly falling through the month. This flooding mainly impacted agricultural land.
