Frøland
Much rain, a steep drop and nearness to Bergen meant that the power-making potential of the Samnanger water system was exploited early. Samnanger was thus one of the first power-producing municipalities in western Norway. With its subsequent expansion and new power stations, about 400 gigawatts of electricity per hour were produced on average each year. This is enough to meet the energy needs of 25,000 households.
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.
Veafjorden
Some decades ago, Veafjord and the currents in toward the bigger rivers were the most likely places to see harbour seals in Hordaland. In the summer flocks lay on the beach and waited for the salmon to trickle in. Sometimes they also followed the fish a little way up the river.
Lønaøyane
The Strandaelvi river is forever protected from the development of hydropower. The Lønaøyane islands – which comprise the delta furthest north in Lake Lønavatnet - are a part of this water system. In 1995 the level of protection for the Lønaøyne islands was strengthened to that of a nature preserve because of the rich birdlife in this wetland.
