Chestnut Hillock Reservoir

The Chestnut Hillock Reservoir is a location in the Commonwealth in Fallout 4. It is a lake located on the South-Western Outskirts of Boston.

Layout
The reservoir is a very small lake surrounded by a few decrepit houses, one of which can be entered (SW corner). There are multiple docks around the lake and an over-turned 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 (Fallout 4) on the ground, and a third is in a bathtub with a Nuka Cola Quantum (Fallout 4).

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".

Notable Loot

 * Edwin's journal holotape can be found in the terminal in the decrepit house.
 * 1 Nuka Cola Quantum held by a skeleton located in a bathtub on the east shore by a building with a fire escape.
 * 1 Master-locked safe located in the decrepit house. The key for the safe is located in the middle of the lake, in a cooler, under the capsized boat. (Upon acquiring the key, two bloatfly will immediately attack the player. Since fighting cannot be done when submerged, running away is recommended.)
 * Annika's locket Found in the right hand of skeletal Edwins remains underwater. (No use but it's a named locket)
 * Edwin's Key underwater in a Cooler container, right below the over-turned boat. If you have accessed the Edwin's journal, when you loot the Cooler of First Aid container next to it there is a very high chance of a scripted Legendary Bloatfly to spawn + generic Bloatfly + Stingwing. Save before you dive to get a legendary item with a desirable effect.
