Description: This dataset was derrived from the National Hydrography Dataset (NHD) and represents NH lakes and ponds greater than 10 acres in size. Lakes and ponds greater than 10 acres in size are subject to the Shoreland permitting process under RSA 483-B, the Shoreland Water Quality Protection Act (SWQPA). Due to the limitations of the original dataset, this shapefile may include shallow, vegetated, waterbodies, as well as open-water systems.
