This datalayer contains polygons representing Massachusetts ponds, lakes, reservoirs, and rivers.
MassGIS has adapted and modified the U.S. Geological Survey 1:100,000 Hydrography Digital Line Graph (DLG) quadrangle files to produce two layers: Hydrography (1:100,000) Polygons - ponds and lakes, Hydrography (1:100,000) Arcs - streams and rivers.
