Bolstadfjorden
Bolstadfjorden is a 12-kilometre-long fjord in Vestland county, Norway, in the municipalities of Vaksdal and Voss. It is part of the Veafjorden system and continues Vikafjorden. The fjord reaches about 160 metres in depth and has a very shallow entrance of about 1.5 metres, which creates strong tidal currents. It covers about 7.1 square kilometres and has a second threshold at 35 metres that splits two basins, with the outer basin about 4.6 square kilometres.
The Vosso River flows into Bolstadfjorden, bringing freshwater from a catchment of roughly 1,500 square kilometres. Freshwater input peaks in May and June. Freshwater on the surface can hinder the deeper, saltier water from mixing, leaving deep water low in oxygen. In 2006, measurements showed no oxygen below 50 metres. The brackish surface layer was about 5 metres deep in April and about 20 metres in August.
A main road, European route E16, runs along the south shore, connecting Bergen with Voss and Oslo. The Voss Line railway originally ran along the south shore through short tunnels. In 1987 the Bergen Line was moved deeper into the bedrock via the Trollkona tunnel (about 8 kilometres long), and the E16 partly used the old tunnels and tracks along Bolstadfjorden.
