The European route E136 highway and the Raumabanen railway line both run along the north side of the lake.

The lake sits on the watershed in the north-western corner of Glomma drainage system that includes large parts of eastern Norway.

The west end of the lake that flows into the Rauma was raised a little when a small stone wall was built.

263 Squadron RAF operated with 18 Gloster Gladiator biplane fighters from a landing strip on the frozen Lesjaskogsvatnet in late April 1940 as part of the Norwegian campaign.

Snow clearing began on 20 April and the same day Norwegian Fokker C.V surveillance planes landed with skis.
