Minor flooding occurred along Box Elder Creek south of highway 14/16, due to melting snow. Water was over 155th, 156th, and 159th Avenues. A bridge at 164th Avenue two miles east-southeast of New Underwood partially collapsed when its supports broke. On March 26, a breach was reported at Quinn Dam; it failed slowly and did not result in any flooding.

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.
