Storofsen is a flood disaster that strikes…
July 1789 CE
Sixty-three persons perish, thousands of houses are totally damaged, and thousands of livestock drowned.
The rivers Glomma and Gudbrandsdalslågen overflood, and the water level of Mjøsa, Norway's largest lake, rises to ten meters above its normal level.
The Kvikne Copper Works are extensively damaged by the flood, and this virtually ends the operation of the mines.
