Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

The National Hydrography Dataset (NHD) represents surface waters of the United States including, rivers, streams, lakes, and coastal features. The Watershed Boundary Dataset (WBD) is comprised of hierarchical polygons called hydrologic units that represent surface area over which water drains to a point. Both datasets are updated by stewards and are available by subsets of the United States.
