The mining of uranium and gold on the northern shore led to the emergence of the village of Uranium City, in which miners and their families settled. Extraction ceased in the 1980s , but the northern coast is still adversely affected by pollution.
The sand dunes adjacent to the south coast are the largest mobile sand dunes in the world north of 58 °. In 1992, the dunes were named "Provincial Wildlife Park."
23 species of fish live in Lake Athabasca, including northern pike , pikeperch , Arctic char , and lake trout [2] ; in 1961, trout with a record weight of 46.3 kg was caught here with the help of a branchial net from the depths.
