The Chestnut Hillock Reservoir is a location in the Commonwealth in 2287.


The reservoir is a very small lake located southwest of Boston, surrounded by a few decrepit houses; the one in the southwest corner can be entered. There are multiple docks around the lake and a capsized boat in the middle of the water. Multiple skeletons can be found on the north side: one in a patio chair has a cooler on the ground near it (there is also a hidden toolbox in the water under this skeleton), another is in a wheelchair with Buffout on the ground and a third is in a bathtub with a Nuka-Cola Quantum.

In the decrepit house, there is a circuit breaker above the terminal that powers a makeshift bug-zapper on the porch.

Ashes the cat can also be found by the Nuka-Cola Quantum. Interact with it to start the quest Here Kitty, Kitty, if this has not been started by speaking to Erin Combes.

Notable lootEdit

  • Edwin's journal holotape can be found in the terminal in the decrepit house.
  • One Nuka-Cola Quantum held by a skeleton located in a bathtub on the east shore by a building with a fire escape.
  • Edwin's key is located in the middle of the lake, in a cooler, under the capsized boat. Two bloatflies will appear and attack upon opening the cooler. The key will unlock the safe in the decrepit house.
  • Annika's locket can be found in the right hand of Edwin's skeletal remains underwater.
  • Two overdue books can be found in a nearby subway station northeast of the lake, including a Vault-Tec lunchbox.


The Chestnut Hillock Reservoir appears only in Fallout 4.
