Event narrative (NOAA)
Heavy rain on top of frozen ground, rivers and streams led to historical runoff on the Niobrara River downstream of the Norden river crossing. At 6:46 AM CDT Holt County Dispatch reported the failure of Spencer Dam. A series of ice jams that developed upstream broke loose that led to a wall of water, large blocks of ice and debris that moved downstream to destroy the dam structure with flood waters to destroy the south bridge abutment on U.S. Highway 281 and the campground, bar and home immediately downstream of the dam. The flood caused one fatality.
