Krækkjavassdraget

Few other animal species on Hardangervidda have been as much the focus of scientific research as the spotted trout. The spotted trout is considered to be a genetic variant of brown trout. It lives in parts of the Krækkjav water system. Otherwise, on a world scale, this species is only found in a small area in Kaukasus, and possibly also in a lake in Rondane.

Granvinsvassdraget

After the ice age, Granvin Fjord reached all the way up under Skjervsfjossen waterfall. Just a thousand years later, as a result of the rising of the land after the ice melted, this whole inner part of the fjord freed itself of the sea and became Granvinsvatnet lake. In spite of this rise in elevation, this waterway is still navigable for fish: Sea trout have wandered into Granvinsvatnet in more recent times and evolved to become freshwater trout. And salmon and sea trout made the journey 13 kilometres up the Storelvi river.

Lure Fjord

Both Lure Fjord and Lindåsosane to the inside give good living conditions for rare marine organisms: jellyfish, shellfish and fish. These include animals that migrated in after last the Ice Age, when the sea level was higher. Eventually, as the land rose, some of these populations became isolated.

Rylandvassdraget

There is a lot of trout and a large char population in Lake Rylandsvatnet. The lake was stocked with char, probably in 1907. The promoters of the project were the family Ameln, who owned eight mills in Rylandsvågen and parts of the Ryland farm.

Salhusfjorden

When the debate about building a pontoon bridge over Salhus Fjord was raging, some were afraid that the bridge would disrupt the ecology of the fjord system inside. The worst predictions did not prove true, but it is easy to see that there was a change: the Puffins have gotten a new food platter after the Nordhordaland bridge was built. Its favourite meal, mussels, thrive on the pontoons that are the foundation for the bridge.

Hellandsfossen

Lonelva

It is said that the salmon populations with the largest and the smallest salmon in the world both come from the waters that run out into the fjord system around Osterøy. Vosso is supposed to have the largest spawning salmon to be found in any river, whereas Lonelva is said to have the smallest.

Mjøsvågen

Around Mjøsvågen here is still a compact marine use area. Some of the buildings are common boathouses, but most of them also house small enterprises and workshops. This is where the farmers from Øvsthus, Mjøs, Hole and other farms have supplemented their meagre incomes as smiths, brass moulders, clog makers, chest builders and decorative painters.

Berge

Down by the fjord on the farm Berge in Tørvikbygd, is Stekkavika – a sheltered eastward facing harbour, protected against the fjord by headlands and rocks, even manifest in the name. Here is also a comprehensive milieu of coastal industry, with boathouses and sea-sheds that belong to the farms Berge, Heradstveit and Halleråker. Belonging to the farm Berge there is also a mill-house, circular saw, workshop for sloop building, and – a little further up into the woods – the old water-powered sash-saw.
