Akkajaure (from lule sami Áhkájávrre) is one of the largest reservoirs in Sweden.[1] It lies at the headwaters of the Lule River in Norrbotten County, in Swedish Lappland, within the Stora Sjöfallet national park. The lake formed after the construction of the first Suorva dam in 1913–1923.[1] The rim of the current dam is at an elevation of 453 m (1,486 ft).[1] When full, the lake's maximum depth is 92 m (302 ft), and its mean depth is about 30 m (98 ft).[1] Because it is used for power generation, the lake depth fluctuates by up to 30 m (98 ft).[1]
