MD-DE-DC WSC Surface Water Capabilities

As an integrated part of the WSC, the Surface Water Team monitors and conducts investigative research to describe and improve our region's understanding of extreme hydrologic events - droughts, floods and flood hazards, and coastal or bay storm surge and inundation. They also facilitate measurement stream stages, streamflow, and computes daily streamflow at locations in Maryland, Delaware, and...

Characterization of Streamflow, Suspended Sediment, and Nutrients in the Upper Yampa River Basin

The Upper Yampa River Basin (UYRB) drains approximately 1,800 square miles west of the Continental Divide in northwestern Colorado. In 2019, the USGS, in cooperation with local stakeholders in the UYRB water community, initiated a study to characterize streamflow, suspended sediment, and nutrients using historic and recently acquired water-quality data from a long-term monitoring program...

Denali National Park Geohazards Geologic Mapping

Denali National Park (DENA) is a major draw for tourism and recreation and a major economic engine for central Alaska. However, the geologic forces that created the steep landscape of DENA also make it prone to geologic hazards (geohazards) like landslides, debris flows, and earthquakes. DENA has only one major road, called the ‘Park Road’, that serves nearly all of its infrastructure.

Pixel by Pixel: How the USGS, U.S. Forest Service Checked the Work of a Computerized Landsat Mapping Project

About a year ago, scientist Bruce Pengra sat at his desk with a conundrum.

As part of the team working on the reference dataset for the USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative’s land cover mapping project, Pengra was staring at a single speck of satellite data, a nondescript blotch of color representing a 30-meter plot of ground in Washington state....

Kansas River Time of Travel Study

The Kansas River provides drinking water for multiple cities in northeastern Kansas and is used for recreational purposes. Thus, improving the scientific knowledge of streamflow velocities and traveltimes will greatly aid in water-treatment plans and response to critical events and threats to water supplies. Dye-tracer studies are usually done to enhance knowledge of transport characteristics...

Offshore Faults along Central and Northern California

From Point Conception to Cape Mendocino, seafloor faults have been, in the past, mapped in varying ways and without enough detail to assess their earthquake potential. To provide this important information, USGS uses advanced technology to image offshore faults that could trigger devastating earthquakes near densely populated areas and a nuclear power plant.

Lake Koocanusa Water Quality

Lake Koocanusa is a transboundary reservoir located in southeastern British Columbia and northwestern Montana. The reservoir was officially impounded in 1972 after construction of Libby Dam, which began in 1966. The dam was constructed as part of a treaty between the United States and Canada to cooperatively develop the water resources of the Columbia River drainage basin. The reservoir has a...
