Storavan is a lake which, like Hornavan, is part of the Skellefteå river system. In the spring Storavan has always been a valuable land for many migratory birds, but it grew again for some time. By pumping water, removing scrub and grazing cows, the valuable habitat has been restored for roosting and breeding birds and today swans, ducks and many other species of birds can be found breeding around the lake.
