Andfiskvatnet

Andfiskvatnet is a lake in Rana Municipality in Nordland county, Norway. The lake lies about southeast of the village of Hauknes and about south of the town of Mo i Rana. The lake flows out into the river Andfiskåga, which flows into the Ranfjorden.

The lake contributes to regional water management, having served as the main source of raw water for the Åga and Haukness waterworks until their closure in 2020, when operations shifted to the Mo i Rana waterworks. Since then, Andfiskvatnet has functioned as a backup source, supplying drinking water to nearby communities and suburbs. It also provides water to the Mo Industrial Park waterworks, supporting industrial activities through a system that channels water from upstream sources to maintain consistent supply levels.
