Iceland has more than 20 lakes that are over 10 square km in size and about 40 lakes that have a size ranging between 2.5 and 10 square km. Some of the lakes in Iceland vary considerably in size between seasons and years. The largest lakes in Iceland include both natural lakes and reservoirs created by damming rivers. Natural lakes in Iceland usually have a glacial or volcanic origin. Here we provide a list of the lakes in Iceland that are over 10 square km in size and describe the five biggest lakes among them.
5. Lagarfljót (Lögurinn)
Lagarfljót, the fifth biggest Icelandic lake, is located near Egilsstaðir in eastern Iceland. The lake measures 53 square km and has a maximum depth of 112 m. The River Lagarfljót flows through the Lagarfljót. The 118 m tall Hengifoss, one of the tallest waterfalls in Iceland, and the Hallormsstaðaskógur, Iceland’s biggest forest are both located near the lake. According to locals, a cryptid serpent called Lagarfljótsormurinn is said to live in the lake.
Blöndulón is the fourth biggest lake in Iceland. It is located in the highlands of Iceland near the Kjölur highland road. The lake encompasses an area of 57 square km and was established as a reservoir between 1984 and 1991. The depth of the Blöndulón is 39 m. The reservoir serves the needs of the Blönduvirkjun power plant.
The third biggest lake in Iceland is the Hálslón Reservoir. It is located on the Jökulsá á Dal River in Eastern Iceland. The reservoir stores water for the generation of hydroelectric power by the Kárahnjúkar Hydropower Plant. The lake is separated from the river by the Kárahnjúkastífla Dam. It is 193 m tall and 730 m long. The construction of the dam was completed between 2003 and 2006.
Þingvallavatn is a rift valley lake located in southwestern Iceland. With a surface area of 84 square km, the lake is the largest natural lake in the country. The maximum depth of the lake is 114 m. The national parliament of Iceland was founded at the northern shore of the lake at Þingvellir and is called the Alþingi. The lake is a part of the Þingvellir National Park. The volcanic origin of the lake is clearly visible from the volcanic features of its islands and the surrounding landscape.
Þórisvatn is Iceland’s largest lake and is located at the southern end of the highland road of Sprengisandur in the highlands of Iceland. The lake is actually a reservoir with an area of about 88 square km. A power station associated with the reservoir harnesses the energy of the Þjórsá river as it flows down from the glacier Hofsjökull. The energy is used to produce hydroelectric power. The lake has a stark green color like most other lakes in the region.
