This is an animation showing the changing conditions relative to the historic record of USGS streamgages from April 1, 2025 to June 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.   

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 recorded webinar details the significance and finding of the National Water Availability Assessment Release. 

This is an animation showing the changing conditions relative to the historic record of USGS streamgages from October 1, 2024 to December 31, 2024. 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 recorded webinar covers what to expect during Campaign One of the NWISWeb Decommissioning, which will occur over 2025.

The sixth and final webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on satellite observations of lake surface water dynamics. John W. Jones of the USGS Hydrologic Remote Sensing Branch introduces the surface water and wetland remote sensing component of the Integrated Water Availability Assessment.

This is an animation showing the changing conditions relative to the historic record of USGS streamgages from October 1, 2023 - September 30, 2024. 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.   

Did you know the USGS is involved in understanding how PFAS travel through the environment?

The fifth webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on waterbird prey availability in Great Basin terminal lakes.

The fourth webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on movement of bird species associated with Great Basin terminal lake ecosystems. Cory Overton of the Western Ecological Research Center gives an overview of the USGS bird movement monitoring strategy and presents results from the 2024 field season.

The third webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on water-quality monitoring of Great Basin terminal lake ecosystems. Christine Rumsey of the Utah Water Science Center and Casie Smith of the Oregon Water Science Center give an overview of the USGS water-quality monitoring strategy and present results from the 2024 field season.

Are you afraid of the dark?

Not this scientist. He is using a special technique to examine sediment samples that can help scientists study historical hurricanes.

The second webinar in the Saline Lake Ecosystems IWAA Fall 2024 Webinar Series is on physical and chemical monitoring in support of water budgets of select Great Basin saline lakes.
