Chestnut Hillock Reservoir

Chestnut Hillock Reservoir is a lake within the neighborhood of Brighton, Boston.

Background
This reservoir was created in 1870 on existing marshes and meadowland to supplement the city of Boston's water needs. It is surrounded by Chestnut Hill, once an affluent village of Newton. Unlike most Massachusetts villages, Chestnut Hill encompassed parts of three separate municipalities, each located in a different county: the neighborhoods of Brighton and West Roxbury, the town of Brookline in Norfolk County, and the city of Newton in Middlesex County. The reservoir, though, is located entirely within the city of Boston.

Of particular note is the cabin on the south shore; it was once the home of Edwin and Annika. They met when he stumbled upon her, she leveling her shotgun at his head. Instead of pulling the trigger, they fell in love; spending their lazy nights stargazing from the porch. It may have been years, decades even since they were there.

Since then the cabin became a raider camp before being abandoned. Edwin vagabonded, only returning here three years after Annika passed, seeking solace in the place where they met and began their life together. He and his brahmin Bess arrived at sundown, September 7, 2287. They settled in and enjoyed their time off the road.

Since he was last there the cabin's north half had sunk more into the shore – he planned to return in the spring to sure up the foundation – and the waters themselves became a breeding ground for insects. In the mean time, it took about a week to clean the raider detritus out of the cabin; to compensate for the local fauna, he built the electric zapper out of parts from an old generator and attached it to the porch roof.

While out fishing on September 17, a large swarm of insects attacked him. He got a few good shots at them, however the scuffle upset the boat and it flipped over. After swimming to shore he made it back to the cabin. With the danger more apparent and his brahmin spooked, he decided to leave in the morning should the bugs not let up.

The following morning he realized that he lost Annika's locket – the only thing he has to remember her by. Nearly hysterical he swam out into the middle of the lake to find it. It was there he would die, clutching the last physical reminder of his deceased love. Bess, left unattended, was attacked and killed. His skeleton lies at the bottom of the lake, beneath the overturned rowboat, and Bess' corpse is in the process of being consumed by the insects.

Layout
A once picturesque pond on the edge of the Fens, this swampy landscape is now infested with bloodbugs, bloatflies, and stingwings. A small dilapidated house rests on the shoreline. Inside is a desk with Edwin's terminal in one corner, and a bed and safe (master locked) tucked into another.

Notable loot

 * Annika's locket, next to Edwin's skeleton at the bottom of the lake, beneath the under capsized rowboat.
 * Edwin's key is in the cooler underwater, directly beneath the flipped boat in front of the pier. It unlocks the master locked safe in the cabin.
 * On the northeast end of the pond is a skeleton in a bathtub clutching a Nuka-Cola Quantum.
