This recording of a public webinar highlights new features of Water Data for the Nation (WDFN) and the NWISWeb decommissioning effort.

This recorded webinar demonstrates how to access and use new modeled water data delivered through the National Water Availability Assessment Data Companion (NWDC). The NWDC is a centralized website providing USGS model-derived water availability, supply, and use information that underlies the National Water Availability Assessment Report.

This is an animation showing the changing conditions relative to the historic record of USGS streamgages from October 1, 2024 - September 30, 2025. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.   

This is an animation showing the changing conditions relative to the historic record of USGS streamgages from July 1, 2025, to September 30, 2025. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.   

The USGS and D.C.’s DOEE have been working together to monitor water quality in the Anacostia, in support of the District's goal of expanding access to the water for local communities. DOEE relies on data and continuous monitoring from USGS to support important decisions about public safety and the accessibility of the area’s natural resources.

Discover what a career in science with the U.S. Geological Survey looks like. The Maryland-Delaware-DC Water Science Center is home to skilled scientists of many disciplines: hydrologists, geomorphologists, geographers, data scientists, statisticians, biologists, technicians, and more. You name it, we need it.

For over 15 years, the USGS has provided machine-readable and automated access to water data via the WaterServices family of APIs.

Westernport, Maryland was one of the hardest hit towns during the mid-May flooding in Western Maryland, where Georges Creek flooded an elementary school in Westernport, MD, prompting the emergency rescue of schoolchildren.

This is an animation showing the changing conditions relative to the historic record of USGS streamgages from January 1, 2025 to March 31, 2025. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.   

This National Map training video will demonstrate how to use QGIS, a free and open-source GIS software, to import and visualize lidar point cloud data from the USGS 3D Elevation Program (3DEP). 

This video gives a step-by-step explanation of how to show daily values vs continuous data from the Location Monitoring Pages in Water Data for the Nation.

This video gives a step-by-step explanation of how to make a current conditions table from the new state pages and My Favorites List in Water Data for the Nation.
