What happened
The episode as NWS ABR wrote it up.
A wet April and early May, including heavy rain producing thunderstorms on May 6th, resulted in the North Fork Whetstone River briefly rising to above flood stage during the evening of May 7th into the morning of May 8th. The nearby Milbank COOP observer recorded 3.37 inches of rain in April and an additional 1.33 inches of rain during the first week of May. The river peaked at 1056.55 feet, or 0.55 feet above flood stage. These high river levels resulted in inundation of agricultural fields, and topped the low water crossing on 479th Ave.
