The lake lies in the Merrimack River watershed. Its outlet, Cascade Brook, flows south over ledges and waterfalls to the Pemigewasset River near "The Basin" in Franconia Notch. The Pemigewasset in turn flows south to the Merrimack River, which reaches the Atlantic Ocean at Newburyport, Massachusetts.
Lonesome Lake is part of Franconia Notch State Park. The Appalachian Trail passes the lake at its outlet. Additional hiking trails travel north to Cannon Mountain.
The lake is classified as a coldwater fishery and contains brook trout.
