USGS Flood Information

The USGS collects flood data and conducts targeted flood science for Federal, State, and local agencies, decision makers, and the public before, during, and after a flood. Our efforts provide situational awareness, drive predictive models, inform infrastructure design and operation, undergird floodplain mapping, quantify flood constituents and loads, and assess ecological impacts of floods....

Streamgaging Basics

The USGS operates one of the largest streamgaging enterprises in the world. At most gages, continuously measured water levels are used to compute hourly (or more frequent) streamflow from gage-specific rating curves developed using onsite streamflow measurements made by USGS hydrographers. The data are quality assured and made available online.

Nutrients and Eutrophication

Like people, plants need nutrients, but too much of a good thing can be a problem. Nutrients, such as nitrogen and phosphorus, occur naturally, but most of the nutrients in our waterways come from human activities and sources—fertilizers, wastewater, automobile exhaust, animal waste. The USGS investigates the source, transport, and fate of nutrients and their impacts on the world around us....

Urban Land Use and Water Quality

Wherever you live, there’s a creek or stream near you. The eighty percent of Americans who live in metropolitan areas are often unaware of the network of urban creeks—many teeming with life—that weaves through our cities and town.
