Lake Quannapowitt

Lake Quannapowitt is a location in the Commonwealth in 2287.

Background
Lake Quannapowitt was a tourist location in the pre-War Commonwealth, which was contaminated by toxic waste dump to a highly dangerous level. The scientists at the local monitoring station had serious concerns about allowing the Lake Quannapowitt bass fishing tournament to continue, to the point they recommended canceling the event.

Due to the scientists' concerns at the site, a sample was sent to the Nahant Oceanological Society for independent testing. The test confirmed the rapid increase in radiation levels and supported the recommendation of closing the lake to the public altogether.

Layout
The lake is small and littered with hostile creatures. On the west bank, there is a Department of Water building guarded by some mirelurks. Inside there is a terminal which indicates that the lake is highly irradiated and has been so since before the Great War. The northeast edge of the lake has a small boat ramp and a couple of picnic tables, where a fishing tournament ad can be found. To the north is a bridge, where random encounters may occur. A pair of streams feed into the east side of the lake and host many bloodleaf plants.

One of the streams leads to a nest of mirelurk eggs inside the sewage pipe underneath the truck with the partially overturned boat. 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. At the center of the lake, there are numerous barrels of radioactive waste. Along the perimeter are several boats and ski-doos, indicating that the water level in the lake was higher in the past. The lake also hides several containers below the surface.

Notable loot

 * Fishing tournament ad - On a picnic table at the boat launch near the green glowing mushrooms on the northern shore.
 * A legal notice and another fishing tournament ad on the desk inside of the monitoring station on the northwest shore.

Appearances
Lake Quannapowitt appears only in Fallout 4.

Behind the scenes
There is a real Lake Quannapowitt located in Wakefield, Massachusetts, a suburban town to the north of Boston. The toxic waste dump echoes a real problem with pollution the lake has faced historically.
