Our Science

LSPA Water Quality Buoy

The buoy is located in Lake Sunapee near Loon Island Lighthouse from May through early November annually. During the winter months, the buoy is tethered in Sunapee Harbor and continues to collect and transmit some data.

Water Quality Monitoring

LSPA has been collecting and recording water quality data from tributaries, lakes, and ponds within the Lake Sunapee Watershed since 1986, tracking short and long-term changes. Long-term data trends help guide LSPA in our efforts to inform and educate the public about the need to be good watershed stewards to maintain or improve our high-quality waters.

Ice in/Ice out Data

Ice Out data has been collected since 1869, and recently LSPA started collecting ice in data as well to keep track of regional climate changes. 

Local Weather Data

LSPA has four weather stations on Lake Sunapee located in Sunapee Harbor, Georges Mills, Herrick Cove and south of the Fells.
