Flood, Tripp

When: March 14, 11:45 PM CST to March 30, 8:45 PM CST
Where: Tripp County, 12.99 mi NW of Hamill to 12.79 mi NW of Ideal
Cause: Ice Jam
Reported by: River/Stream Gage
Coordinates: 43.720, -99.880

A large ice jam formed along the White River around the SD Highway 47 bridge. Water backed up behind the ice, causing flooding of hundreds of acres of agricultural land. The high water inundated several outbuildings and approached a home along Highway 47. The river crested just below 25 feet on March 19. With continued snowmelt, additional rises were recorded, resulting in a second crest of 20.5 feet and a flow around 37,900 cfs on March 25, which was the third highest flow of record at this location.

What these are

Flood: Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.

After NWS Directive 10-1605, the rules offices file Storm Data by.
