Lake Eloise is a former fishing destination with a number of small islands inside of it. Facing northeast towards the nearby Fissure site Gamma, there is a section of the shore that has been split by the water, though the land is connected by a short wooden bridge. Further southeast is a decorated dock that leads out to a ruined house, which may be occupied by a scavenger.
- Little girl's note - Note, in a destroyed house on the east bank of the lake.
- Potential magazine - In the far northeast part of the wilderness area (northeast of the fissure site), inside the gaming enthusiasts' camp, on the TV behind the woodblocks spelling "CHEATER," on the rocks.
Lake Eloise appears only in Fallout 76.
