As part of taking inventory of park water resources, the I&M Program and the NPS Water Resources Division (WRD) partnered with the U.S. Geological Survey, states, and other agencies to create the National Hydrography Dataset. This dataset includes information on surface waters such as watersheds, glaciers, streams, rivers, canals, reservoirs, and more.
