NHDES Releases Updated New Hampshire Lake Information Mapper

The New Hampshire Department of Environmental Services (NHDES) has updated its interactive surface water quality map, the New Hampshire Lake Information Mapper. In addition to providing links to historical and current lake trophic survey reports, current volunteer lake assessment program reports, and exotic aquatic species distribution information, the Mapper now includes links to Total Maximum Daily Load (TMDL) reports, Diagnostic Feasibility Studies, and Watershed Based Plans. Known ice cover information and cyanobacteria bloom history is also provided. More than 1,700 reports covering more than 1,000 waterbodies from 1975 to 2018 are available via this map.

This interactive map allows the user to zoom in and click on a lake of interest and access a pop up menu that displays the lake name, waterbody ID, trophic status, reports by year, and other information.
