The reservoir is a very small lake 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.
