Røssvatnet

Røssvatnet is a large freshwater lake in Nordland county, Norway. It lies in the northern part of the country, within the Helgeland region. It is one of Nordland's largest lakes by surface area and is a notable geographic feature in the inland valley systems.

The lake's waters are fed by several mountain streams and small rivers, receiving meltwater from the surrounding peaks. It drains through rivers and channels that connect to the regional watershed, forming part of a broader hydrographic network in Helgeland. The landscape around Røssvatnet comprises forests, wetlands, and alpine terrain.

The natural environment supports Nordic freshwater species. Anglers visit for fishing for species such as Arctic char and trout. The shores host a mix of cabins, farms, and small settlements, with popular activities including boating, swimming, and hiking along established paths.

The name Røssvatnet derives from local place names; the lake has long been part of local livelihoods, including forestry and grazing. It has also been considered in regional discussions on water resources and recreation.
