Lake Quannapowitt

Lake Quannapowitt is a location in the Commonwealth in Fallout 4.

Layout
The lake is small and covered with hostile creatures. On the west bank there is a Department of Water building guarded by some mirelurks. Inside there is a computer that indicates that the lake is highly irradiated and also had been so before the the Great War. To the north a is bridge, where the player character may encounter a battle between super mutants and a glowing mole rat.

There are several boats and ski-doos along the perimeter that may have been in the lake when its water level was higher. To the east is Radio Tower 3SM-U81 which can be accessed by following the road, patrolled heavily by mirelurks. The lake also has a sort of billabong off to the east side.

Appearances
Lake Quannapowitt only appears in Fallout 4.
