It consists of two lakes, ''Northern Dellen'' and ''Southern Dellen'', appreciated among fly-fishermen for their distinct population of [[brown trout]]. Southern Dellen has a surface area of 52 km² and a water volume of 1,226 million m³. Northern Dellen has an area of 82 km² and a water volume of 1,489 million m³. The two lakes are only united by a short channel so it is disputed whether they should be counted as one or two lakes. If counted together, it would have a total area of 130 km², making it the 18th largest [[Lakes of Sweden|Swedish lake]]. The vaguely circular lake system was formed by a [[meteorite]] [[impact crater|impact]] 89.0 ± 2.7 [[million]] [[year]]s ago placing it in the Upper [[Cretaceous]]. The resulting impact crater measures about 19 [[kilometre]]s in diameter. It has resulted in the area containing the rock [[Dellenite]], which has become the provincial rock of the province. [[Asteroid]] [[7704 Dellen]] was named after it. == Source == * [http://www.dellenbygden.nu/dellenbygden.htm Dellen Information and map] Dellenbygden.nu; in Swedish only ==External links== *[http://www.unb.ca/passc/ImpactDatabase/ Earth Impact Database] [[Category:Craters of Sweden]] [[Category:Cretaceous craters]] [[Category:Lakes of Sweden]] [[Category:Hälsingland]] [[de:Dellen]] [[eo:Dellen]] [[lt:Delenas]] [[sv:Dellensjöarna]]
