Blöndulón
At 57 km2, Blöndulón () is one of Iceland's largest lakes. It was created in 1984-1991 as a reservoir for the Blönduvirkjun power plant, and has a depth of 39 m. It is situated near the Kjölur highland road in the Highlands of Iceland. The hot springs of Hveravellir are situated some 25 km to the south.

List Of Lakes Of Iceland
This is a list of lakes of Iceland (partially indicating surface, depth and volume). Iceland has over 20 lakes larger than 10 km² (4 sq mi), and at least 40 others varying between 2.5 and 10 km² (1 to 4 sq mi) in size. This list also includes a few smaller lakes and ponds that are considered notable (for example Tjörnin in Reykjavik). The figures for many of the smaller lakes are unreliable. Also, some larger lakes vary considerably in size between years or seasons or, for the reservoirs, according to the needs of power plants. Some power plant reservoirs may not be present despite being larger than listed lakes.

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Blanda
The Blanda () is a river in Iceland which flows northwards from the northwest side of the Hofsjökull glacier into Húnaflói bay at Blönduós. The Blanda is one of the longest rivers in the country, with a length of about 125 km, and has a catchment area estimated at 2370 km2. Its source is calculated to lie at a height of 800m. The river is one of the main salmon rivers in Iceland and has often yielded a catch of almost 3000 salmon in one summer. Before the river was dammed in 1990, the salmon spawning grounds reached almost to the foot of the glacier. Blanda hydroelectric Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and ... power station uses the drop of the river to generate up to 150 MW of power.

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Landsvirkjun
Landsvirkjun, () the National Power Company of Iceland, is Iceland's largest electricity generator. Landsvirkjun operates 18 power plants in Iceland concentrated on five main areas of operation. History Landsvirkjun was founded on 1 July 1965 by the state of Iceland and the city of Reykjavík. The city of Reykjavík contributed to the company three power stations on the Sog River. Shortly after its founding construction on the Búrfell hydropower station began. From 1965 until 2005 the purpose of Landsvirkjun was to produce and distribute high voltage electricity. The municipality of Akureyri acquired a 5% share in Landsvirkjun in 1983 and became the third owner. Three hydropower stations on the Laxá River previously owned by the municipality of Akureyri were merged into Landsvirkjun. The hydropower stations Búrfell, Sigalda, Hrauneyjafoss, Blanda, Sultartangi, Vatnsfell, and Fljótsdalsstöð were all built by Landsvirkjun. The geothermal power station Krafla came under Lan ...

Route F35 (Iceland)
Kjalvegur () is a highland road in Iceland, crossing Kjölur from north to south. History Formerly, the name referred to a horse-track closer to Langjökull, west of the current road. This track now goes by the name ''Kjalvegur hinn forni'' (Ancient Kjalvegur), and is closed to motorized traffic. Geography The road begins in the south of Iceland near Haukadalur and behind the Gullfoss waterfall, ending in the north near ''Blönduós''. The road traverses the interior between two glaciers, Langjökull and Hofsjökull. It is the second longest of the roads through the Highlands of Iceland. It takes about 5 hours to traverse by car, the road is generally rough, but river crossings are bridged. See also * Route 35 (Iceland) * Sprengisandsleið * Kjölur Kjölur () is a plateau in the highlands of Iceland, roughly defined as the area between the Langjökull and Hofsjökull glaciers.

Highlands Of Iceland
The Highlands of Iceland ( is, hálendið ) are a sparsely inhabited plateau that covers most of the interior of Iceland. They are situated above 400–500 metres (1300–1600 feet) and are mostly an uninhabitable volcanic desert, because the water precipitating as rain or snow infiltrates so quickly into the ground that it is unavailable for plant growth. This results largely in a surface of grey, black or brown earth, lava and volcanic ashes. A few oasis-like areas, such as Herðubreiðarlindir near Askja, are found only in proximity to rivers. Icelanders categorise the Highlands as: * "Háls", meaning a broad mountain ridge between valleys, such as the one near Langavatn north of Borgarnes; or * "Heiði", meaning the real highlands, such as those alongside the Sprengisandur road. Most of the numerous glaciers, such as Vatnajökull, Langjökull and Hofsjökull, are also part of the Icelandic Highlands. Vegetation is only found on the shores of the glacier rivers. There is al ...

Hot Springs
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust. In either case, the ultimate source of the heat is radioactive decay of naturally occurring radioactive elements in the Earth's mantle, the layer beneath the crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its ...

Hveravellir
Hveravellir () is a geothermal field (high temperature field) of the Oddnýjarhnjúkur-Langjökull subglacial volcanic system in the north of Langjökull glacier. Description Hveravellir geothermal area is a small nature reserve and a tourist centre located in 600 m a.s.l. at the Kjölur mountain route between the glaciers Hofsjökull and Langjökull, Central Iceland. It is part of the Oddnýjarhnjúkur-Langjökull volcanic system. The place has been a popular resting place in highland travels since the age of settlement, 1100-1200 years ago. It is frequently mentioned in the old sagas, annals and folklore. Refuge huts have been situated there from the early beginning. The main geothermal activity is at the northern border of the large lava shield Kjalhraun . The main geothermal area covers around 2.5 km². The hot springs are of various types, geysers, fumaroles, solfataras, boiling pits and warm springs with lower temperatures. The currently active geysers only have smal ...
