Döda fallet/1796 Ragunda lake burst disaster
Located in the eastern part of the province of Jämtland in Sweden, Döda fallet (English: dead fall) is a former whitewater rapid in of the river Indalsälven. On 6 June 1796, following an unusually heavy flood, lake water started to leak into the canal. The porous ground beneath the canal could not withstand the force of the water, which at 9 p.m. started to quickly erode deep into the esker and the sediment below it. The lake emptied in four hours and, although it was one of Sweden's largest environmental disasters, no one is believed to have been killed by the event, because it was night and their houses were on high ground.
