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.

Knarrevik

Having passed well over the bridge across to Sotra you pass an industrial plant surrounded by a budding community; the mineral mill of A/S Norwegian Talc. Some of the buildings seem to have been erected in the early part of the 20th century. They are remnants of a grand industrial plant from the former boom time in the country – the economic upswing after WWI.

Tysse

As early as 1862 Svein L.Røsseland started a country store and lodging house at Ytre Tysse, and later on he became steamship agent and the first post office manager in Samnanger. However, the decisive change came when F.Mathiessen started A/S Samnanger Uldvarfabrik (woollen factory) in 1886.

Glesvær

He wondered, surely, the fisherman who in 1769 found a 3.3 metre-long silvery shining sea creature at Glesvær. Perhaps he hadn't heard the legend about the sea snake. If so, he must have thought that that was what he had found, for the sea creature resembled more a fantasy figure of a sea snake than any fish he had ever seen.

The industrial settlement Bjørsvik

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.

Matre- Salmon spot

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.

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.
