Where: Jones County, 8 mi W of Okaton to 2.43 mi WSW of Okaton
Cause: Ice Jam
Reported by: River/Stream Gage
Coordinates: 43.880, -101.060

Ice jams, combined with runoff from snow melt, caused moderate flooding along the White River. On March 22nd, the river forced the closure of Highway 83. About a 3/4 mile stretch of Highway 83 was inundated, due to water backing up behind and ice jam downstream. On March 23rd, a record flow of 21,700 cfs was recorded at the site. Records for this location go back 20 years.

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.
