Crescent Lake, as Halfmoon was known, circa 1940

On the Alton-Barnstead line, Halfmoon Lake is a 280 acre natural body of water with a maximum depth of 29 feet and at an elevation of 640 feet. This glacial formed lake, just off Route 28, has a substrate of 75% sand and 25% rock, and a 90% wooded and 10% marsh shoreline. Halfmoon boasts good availability of large- and smallmouth bass, yellow and white perch, hornpout, and also a summer abundance of pumpkinseed and bluegill sunfish. Ice-out is usually expected by late April, though often earlier.

The above image of Halfmoon Lake, previously know as Crescent Lake, is from a double postcard dated 1940, though it is probably of a photograph taken at an earlier period.
