This lakebed is a stretch of dried-up land that separates Clarksburg and Wavy Willard's Water Park, irradiated from chemical dumping and the effects of the Great War. Its point of discovery is within Clarksburg, near an inaccessible Crab Shack. There is a pathway that leads up to the roof of the restaurant, where there is a small survivalist's camp with some loot. There are number of other buildings along the edge of the lake, including a couple of boat houses, one of which is locked and has a red steamer trunk inside. There is also a diner named Lakeside Grill with various junk items. At the center of the lake is a spawn for a large creature such as a mirelurk queen or a Grafton monster.
- Untitled - Note, found on a picnic table on a small wharf, slightly east of the diner.
- Boat house key - In the diner, near a bubblegum bear in a cooking pot. Opens the locked boat house.

The toxic dried lakebed appears only in Fallout 76.
