Information about Þjórsá

 

The majestic Thjorsa is Iceland‘s longest and second-most volumnous river. The 230 meter long river has its source at the glacier Hofsjokull and has several tributaries, the two largest being Tungnaa, and Kaldakvisl, which both have their origins by Vatnajokull glacier. Thjorsa river also divides the counties Rangarvallasysla and Arnessysla.

Sights & activities

On its way southward, Thorsa passes a lava field named after the river, Thjorsarhraun, covering some 26 km2. This lava flowed some 7800 years ago and was one of the greatest postglacial holocene fows in the world,

Many beautiful waterfalls are found in the river, i.e. Kjalkaversfoss, Dynkur, Gljufurleitarfoss, Budafoss, Hestfoss and Urridafoss. Additonally, there are Trollkonuhlaup, Minna-Nups Fludir and Thjofafoss, but these waterfalls have been affected by irrigations in the river.The river also has several small islets, the largest being Hagaey and Arnes, wherefrom Arnessysla county takes its name.

At Arnes you can see the ruins of an ancient local parliament, Arnesthing. Also notable on the island is the hill Thingholl (‚Parliament hill‘) and the hanging rocks known as Galgaklettar (‚Gallows Rocks‘). The name suggests that this place was used for executions in former times.

Also notable is the islet Videy, as it is naturally preserved due to its rich birchwood and for featuring over 70 species of vascular plant. Two of these are particularly rare in Iceland.   

Thjorsa offers great opportunities for fishing. Salmon, trout, tar, salmon trout, stickleback, eel and the European Flounder are all found in the river. Indeed, Thjorsa and its tributaries are among the most abundant salmon rivers in the country. Seals are also found in the river and have long been hunted there. Last, but not least, rafting on Thjorsa is a popular and exhilarating experience.

Crossing the river

The river can be crossed by two bridges, the older, by Thrjotandi, originally built in the 19th century and reconstructed a bit lower in the river in 1949, and the younger by Sandafell, slightly below the Sultartangi power station. 

Power stations

The river has five hydropower stations, built by Landsvirkjun. These are Burfellsstod, Sultartangastod, Hrauneyjafossastod, Sigoldustod and Vatnsfellstod. The Budarhals powerstation is set to be completed in December 2013 and there are plans for three more, in the lower part of Thjorsa; Hvammsvirkjun, Holtavirkjun and Urridafossvirkjun.
