Botsvatn

Botsvatn or Bossvatn is a lake in the municipality of Bykle in Agder county, Norway. The long, narrow reservoir is located just to the southeast of the large lake Blåsjø and northeast of the lake Ytre Storevatnet. The lake holds water for the Brokke Hydroelectric Power Station, located in nearby Valle municipality. The water from the lake can flow out into the nearby river Otra, but only when water is released from the dam.

The village of Nordbygdi is located on the north shore of the lake, and the village of Bykle is located about to the east of the lake along the Norwegian National Road 9. The mountain Steinheii lies on the south shore of the lake and the mountain Strondefjell lies on the north side of the lake.
