Summary
Description
This map layer contains waterbodies and wetlands of the United States, Puerto Rico, and the U.S. Virgin Islands. The map layer was produced primarily from the Medium-Resolution and High-Resolution National Hydrography Dataset NHDWaterbody feature classes, through feature selection and cartographic generalization based on reference to published small-scale ancillary data sets. This is a revised version of the July 2012 map layer.
