Description: <div>The National Hydrography Dataset Plus (NHDplus) maps the<span> lakes, ponds, streams, rivers and other surface waters of the United States. Created by the</span> <a href='https://www.epa.gov/waterdata/basic-information' rel='nofollow ugc' target='_blank'>US EPA Office of Water</a> and the <a href='https://www.usgs.gov/core-science-systems/ngp/national-hydrography' rel='nofollow ugc' target='_blank'>US Geological Survey</a>, the NHDPlus provides mean annual and monthly flow estimates for rivers and streams.
