In September 1345, there was a landslide just north of the village of [[Støren]]. The landslide was at a very narrow point in the valley and possibly {{convert|45000000|m3|yd3}} of gravel and dirt from the mountainside fell and blocked the valley and [[Gaula (Trøndelag)|Gaula]] river below creating a [[dam]] on the river that was possibly {{convert|30|to|40|m}} high. This tremendous landslide then created a quickly rising lake that began to flood the valley up to {{convert|15|km}} upstream from the dam. This newly formed lake flooded and destroyed 25 upstream farms in the narrow valley. The vast amount of water building up behind the earthen dam from the landslide did not hold long and, when it burst, the water rushed though the dam and caused a major flood downstream, killing about 500 people and destroying another 25 farms as well as several churches. The downstream flash flood continued to just past the village of [[Melhus (village)|Melhus]], not far from the mouth of the river Gaula. This was one of the worst natural disasters ever in Norway.<ref>{{cite journal|title=The 1345 slide and flood disaster in the Gauldalen valley, Mid-Norway|first1=Kåre|last1=Rokoengen|first2=Martin Nørman|last2=Jespersen|first3=Rolf Arne|last3=Kleiv|first4=Einar|last4=Sæterbø|journal=Norsk Geografisk Tidsskrift - Norwegian Journal of Geography|volume=55|issue=2|year=2001|doi=10.1080/00291950121138}}</ref>
