Located south of the Grandchester Mystery Mansion, the lake is shallow and has some pockets of radioactivity emitting approximately 10 rads per second. It is occupied by around half a dozen mirelurks, including a submerged queen in the center of the lake. Several bloodleaf, silt bean, and tarberry plants are in the area.
Two explosives boxes are on the northern shore, one next to a red car, and the other next to a shipping container. Behind the queen, to the south by a broken tree, is a skeleton sitting next to a steamer trunk, an ammo box, a minigun, and some loose ammo (which may include a fusion core).
