Once a recreational area on the outskirts of Lewisburg, Lake Reynolds was closed down and abandoned before the Great War due to the mounting pollution from The Ash Heap. Now it's little more than a stopover point. After the Great War, the lake was used as a camp by the Responders. The corpses of some of their members can still be found in the location.
Lake Reynolds sits to the southwest of the Lewisburg station. In its immediate vicinity are a small building, a campsite, a playground and a few dilapidated fairground rides from the pre-War era. The building has posters in its windows advertising the attractions in the area - a Ferris wheel, paddle boats, and "Twister." There is a weapons workbench outside the building but the building itself is boarded up and inaccessible.
A Responder corpse lies next to a truck parked between the building and a small campsite with a tent. Further to the west of the lake is what remains of the advertised Ferris wheel and another ride with swings - presumably the "Twister." The lake itself has little of note, though there are patches of land running through the middle of it that make crossing the water easier.
A number of wood piles and logs can be found here, making it a good source for gathering wood.
Lake Reynolds appears only in Fallout 76.
