Hornavan [′hu|rna|van] is a lake in northern Sweden. It is located in Arjeplog Municipality in the province of Swedish Lapland, administratively known as Norrbotten County.

Geography

It is situated among the Scandinavian mountain range, at a height of 425 meters. The town Arjeplog is located by its south-western shore. The lake then extends 70 kilometers northwest up to the town of Jäckvik, containing about 400 islets, many of which have distinguishable floras and faunas. Research on the ecosystems comparing larger islands with smaller islets in Hornavan and Uddjaur are popular due to their unpolluted environment, and have given rewarding results. An international study was published in Nature entitled "Effects of species and functional group loss on island ecosystem properties."

On its southern end, the lake attaches with the lake Uddjaure.

The surface area fluctuates between 220 and 283 km², but some sources give it as constant 251 km²; in any case, it is the eighth largest lake in Sweden. With a largest depth of 221 meters it is also the deepest.

The lake has been cultivated for water power. All lakes in Arjeplog Municipality have drinkable water.

Fishing

Animalwise, it has 5 native kinds of whitefish: "Coregonus pallasii, Coreganus megalops, Coreganus maxillaris, Coregoni nilssoni" and "Coreganus widegreni" (the latter known under the name Valaam). , with a sixth, "Coreganus maraena", planted in the 1940s.

The most popular sport-fishing catches are otherwise trouts, which is best done trolling.
