Site details

A clear 240-acre glacial lake at about 1,480 feet elevation beneath Mount Monadnock, popular with regional divers and training classes. Shore access points along the northeastern shore off Route 101 lead to a bottom that slopes steeply to about 60 feet past glacial boulder fields before flattening into silt that reaches 90-110 feet. Visibility averages over 30 feet, unusually good for a New England lake; altitude diving procedures apply.
