Located in Arjeplog Municipality in the province of Swedish Lapland, administratively known as Norrbotten County, it is the deepest lake in Sweden. GeographyIt is situated among the Scandinavian mountain range, at a height of {{convert|425|m}}. The town of Arjeplog is located on its south-western shore. The lake then extends {{convert|70|km2|abbr=on}} northwest up to the town of Jäckvik, containing about 400 islets, many of which have distinguishable flora and fauna. Research on the ecosystems comparing the larger islands with smaller islets in Hornavan and Uddjaur are popular due to their unpolluted environment, and have yielded {{clarify|date=January 2017|text=rewarding results}}. In June 2005 an international study was published in Nature entitled Effects of species and functional group loss on island ecosystem properties.[1] On its southern end, the lake attaches with the lake Uddjaure. The surface area fluctuates between {{convert|220|and|283|km2|abbr=on}}, but some sources give it as constant {{convert|251|km2|abbr=on}}; in any case, it is the eighth largest lake in Sweden. With a largest depth of {{convert|221|m}} it is also the deepest. The lake has been cultivated for water power. Hornavan, like all lakes in Arjeplog Municipality, has drinkable water. FishingIn terms of animal life, it has 5 native species of whitefish: Coregonus pallasii, Coregonus megalops, Coregonus maxillaris, Coregonus nelssonii and Coregonus widegreni (the latter known under the name Valaam), with a sixth, Coregonus maraena, introduced in the 1940s. The most popular sport-fishing catches are otherwise trouts, which is best done by trolling. Sources
