Science Summary
Record Amounts of Rainwater Flow off the Land into Chesapeake Bay
As the Mid-Atlantic states' super-soaker summer draws to a close, record amounts of rainwater have flowed off the land and into Chesapeake Bay, with potential consequences for the nation's largest estuary. USGS measurements show freshwater flows into the bay in August 2018 were the highest ever recorded for that month by a wide margin. River flows into the bay have been unusually high since...
Streamflow in the Watershed and Entering the Chesapeake Bay
The health of the Chesapeake Bay, and streams in the watershed, are affected by changes in surface-water flows. Runoff from storms carries pollutants, such as nutrients, sediments, and toxic contaminants, into streams throughout the 64,000 square-mile watershed, which drain to the Bay. The changes of stream flow, and associated pollutant loads, influence habitat conditions for fisheries and...
USGS data is foundation for new dissolved oxygen forecast
USGS data is the foundation for the new dissolved oxygen forecast. A large summer ‘dead zone’ is forecast for the Chesapeake Bay after a wet winter and spring.
