About

This is an interactive map of Lake Winnipesaukee water quality monitoring sites. The sites shown on the map are not necessarily all currently monitored, but show both historical and active sites. In most cases, the sites are monitored by volunteers in UNH’s Lakes Lay Monitoring Program; however, there are some stations that the NH Dept. of Environmental Services samples as part of their lake survey data.
