Lake Sunapee Protective Association



Lake science (limnology) began in earnest on Lake Sunapee in the 1950s, with water quality measurements. These resulted in Lake Sunapee being classified as “A” or adequate as drinking water. Since that time, many studies have been done on Lake Sunapee, the surrounding lakes and the watershed.
