Streams and Environmental Change
Streams and Environmental Change
Climate change and variability, along with adjacent land use, can affect stream conditions and health. The USGS is providing science on changes in stream flows and temperatures on habitats important for fisheries. The findings will help address the Chesapeake Bay Program (CBP) Goals for fisheries, habitat, and water quality.

New information on chemical and physical characteristics of streams and floodplains across the Chesapeake Bay and Delaware River watersheds
Issue: Improving stream health is an important outcome of the Chesapeake Bay Program partnership. Stream conditions are important for recreational fisheries, and mitigating the amount of nutrients, sediment, and contaminants delivered to the Bay.
New dataset available on stream and floodplain geometry to inform restoration decisions
Issue: The need for stream mapping The physical shape of streams and floodplains can provide information about how water, sediment, and other matter moves through the landscape. Streams can have deep channels (tall streambanks) disconnected from the floodplain or wide shallow channels that easily spill over the banks into the floodplain during high flows. Mapping where streams fall along this...
Projecting stream conditions under future land-use and climate scenarios
Issue: Global change, particularly changes in land use and climate, is dramatically altering stream conditions throughout the world. Healthy streams are important for freshwater fisheries, wildlife, and public recreation. The Chesapeake Bay Program (CBP) has a goal of improving the health of streams throughout the Chesapeake Bay watershed, which includes an outcome of improving the condition of 10...
Tripod-palooza—USGS Collaborates with Federal, State, and Academic Partners to Support Coastal Resiliency in the Wider Chesapeake Bay Area
In the Chesapeake Bay area, the Virginia and West Virginia Water Science Center is partnering with over a dozen organizations in a pilot project this fall, resulting in the establishment of a baseline reference for an ongoing effort in monitoring coastal subsidence.

USGS results used to help develop climate indicators
The USGS stream-water-temperature trends in the Chesapeake Bay region are used for the National Climate Change indicator report released by U.S. Environmental Protection Agency (EPA) entitled Climate Change Indicators in the United States, 2016.
