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.

Sysendammen

Dale power station

In 1923 Bergenshalvøens Kommunale Kraftselskap (BKK) expropriated large areas for power plants and development of hydropower started soon afterwards. Dale power station with the two first aggregates, each of 14 MW was put into operation on 17 November 1927. In the supply reservoir in Storefossen 5152 cubic metres of concrete were cast, and a modern and well-equipped power station was built.

Eksingedalen- hydropower development

Water discharge at the outlet of the Ekso into Eidsfjord was halved after the big hydropower development in the mountainous area between Modalen and Eksingedalen and further southward toward Evanger in the 1960s, 70s and 80s. In an attempt to amend the changed environmental conditions in the waterway the developer built 35 small dams in the river.

Straume- maritime environment

Gåssand

The 28th November 1914 was a day to remember for the Os inhabitants. This was the day they could turn the switch on the wall and have electric light in their houses. It was like opening the door on the future when the power station at Gåssand was put into operation.

Lyse chapel

The small white-painted chapel with the red brick tiled roof just south of the monastery ruins at Lyse was built in 1663 as a local chapel for the monastery estate, following the takeover of the property by the District Recorder (Stiftskriver) Niels Hanssøn Schmidt two years previously. The chapel, with its harmonic proportions, lies in the cultural landscape beside the grand monastery estate, witness to a time gone by. But even today, there is a tradition of high mass on the 2nd day of Ascension in Lyse Chapel.

Lysekloster- The monks and nature

Lysekloster was the largest agricultural property in the country when it was phased out during the Reformation in 1537. In its prime this cloister encompassed two-thirds of all the farms in Os. The monks introduced and cultivated new plant species and it was probably they who stocked the waters with fish not indigenous to the area. This legacy from the Middle Ages has left a lasting mark.

Oselva

Oselvo is the biggest waterway on the Bergen peninsula, with sources in Gullfjellet and Sveningen. There is a fall of only 60 metres along the entire stretch from Samdalsvatnet Lake to the sandbank in Fusafjorden. It is rare to see a river like this in western Norway. There is salmon along this entire section of the Oselvo river.
