The 21-square-kilometre (8.1 sq mi) lake would have been part of the saltwater Larviksfjorden, had it not been dammed by an end moraine left by the latest ice age. That moraine is about 1 kilometre (0.62 mi) wide, separating the lake from the sea. There is a short river that runs through the moraine which drains the lake into the fjord. The lake Farris is a drinking water reservoir for about 170,000 people in the region.^[2]

The largest island in the lake is Bjørnøya, located just east of the village of Kjose. The mineral water brand Farris is named after the lake.
