Shoreland Jurisdiction - Lakes and Ponds

This dataset maps lakes and ponds greater than 10 acres in New Hampshire that are subject to regulation under the Shoreland Water Quality Protection Act (RSA 483-B). Derived from the National Hydrography Dataset (NHD) and refined by the New Hampshire Department of Environmental Services (NHDES), it provides a statewide reference for identifying shoreland jurisdictional areas for permitting, planning, and environmental protection. The data includes both open waterbodies and vegetated or shallow systems and should be used as a general guide, not a definitive legal boundary.
