Provides bathymetric depth contours in feet for New Hampshire lakes surveyed by the New Hampshire Department of
Environmental Services since 2000 and New Hampshire Fish and Game.
This dataset was created to calculate lake volume for lake trophic classification and to provide lake
stakeholders with a bathymetric map. USE THIS DATA AT YOUR OWN RISK

The points were plotted over USGS topographic quads and reviewed for positional accuracy as well as thoroughness of coverage for the water body being mapped.
Data submitted by New Hampshire Fish and Game was assigned the appropriate AUIDs and incorporated into the rest of the bathymetry. Data that overlapped with existing bathymetry was not used.
