Samsjøen is a lake in Trøndelag county, Norway. The 10km2 lake sits on the border of the municipalities of Midtre Gauldal and Melhus. Most of the lake lies in Midtre Gauldal, about north of the village of Singsås. The lake has a dam at the northwest end, which is used for hydroelectric power production. The water flows out of the lake and into the Lundesokna river which flows into the river Gaula.[1]
