Grab our data (and see where we work)
We operate and maintain extensive monitoring networks and conduct hydrologic investigations to quantify each component of the hydrologic cycle.
Northeast region drought streamflow probabilities
Explore drought probabilities for select streams estimated using maximum likelihood regression. Winter streamflows are used to estimate the chance of hydrologic drought during summer months 5 to 11 months in advance.

Explore our scientific and data-driven web tools that include data visualizations, digital repositories, and interactive maps with data access and data analysis capabilities.
Loads and trends in the Chesapeake Bay nontidal monitoring network
Access tools for exploring primary findings for short-term nutrient and sediment trends from the Chesapeake Bay Program’s 123 nontidal network stations.
Featured science: Hydrological Drought Probabilities
Climate change raises concern that risks of hydrological drought may be increasing. We estimate hydrological drought probabilities for rivers and streams in the United States using maximum likelihood logistic regression.
Virginia and West Virginia Water Science Center
We operate streamgages, observation wells, and monitoring stations that provide reliable scientific information needed to make informed decisions. We use advanced science and analytical methods to investigate and understand our natural world.
