Akkajaure, Hydroelectric reservoir in Stora Sjöfallet National Park, Sweden.
Akkajaure is a reservoir at the headwaters of the Lule River in Norrbotten County, inside Stora Sjöfallet National Park. The Suorva dam holds it at 453 m above sea level; when full it reaches 92 m deep, with a mean depth of about 30 m. Its surface covers between 94 and 260 km², and the water level moves between 423 and 453 m. The mountain Akka lies south of the lake.
The reservoir was created by the construction of the Suorva dam starting in the early 1900s, marking a major industrial development in the region. This project harnessed the river's power for electricity generation and shaped the modern landscape of northern Sweden.
The name comes from the Lule Sami language, reflecting the indigenous roots of this part of Lapland. Local Sami culture remains visible in how people relate to this landscape and its resources.
Water levels change significantly due to hydroelectric operations, affecting fishing conditions and water activities throughout the year. Visitors should check current conditions before planning water-based activities or accessing shoreline areas.
The Suorva dam raised water levels by up to 30 metres, submerging a maze of small lakes, islands and shoreland; before flooding, Gustaf Hallström, Axel Calleberg and Otto Lindgren recorded archaeological finds, Sami place names and local legends in 1922. South of the reservoir lies the mountain Akka.
