LSPA has been collecting and recording water quality data from tributaries, lakes and ponds within the Lake Sunapee Watershed since 1986. Ice out dates have been observed and recorded since 1869. This data is primarily used by LSPA, the NH Department of Environmental Services, scientists, and students to track short and long-term trends. This information is useful for understanding change in water quality conditions in regional lakes, ponds and streams. Long term data trends help guide LSPA in our efforts to inform and educate the public about the need to be good watershed stewards if we are to maintain or improve our high-quality waters.
