Chesapeake Bay Activities
The Chesapeake Bay is our Nation’s largest estuary and provides over $100 billion in annual economic value. The USGS works with Federal, State, local, and academic partners to provide research and monitoring and to communicate results to inform management for the Chesapeake and other important landscapes across the Nation.
“Sediment Shadow” in Chesapeake Bay’s Tidal Freshwater Rivers
“Sediment Shadow” in Chesapeake Bay’s Tidal Freshwater Rivers
A new synthesis of existing long-term records of suspended-sediment concentrations suggests that only a limited amount of watershed sediment is currently transported by rivers past the tidal freshwater zone and into saltier waters of the Chesapeake Bay.
Stream-Restoration Practices in an Impaired Agricultural System
Stream-Restoration Practices in an Impaired Agricultural System
A study in Turtle Creek, Pennsylvania, suggests that stream-restoration practices can significantly reduce streambank erosion and enhance floodplain deposition, changes that can reduce in-stream sediment loads and improve habitat for fish and other stream biota.

Long-term predictive modeling of stream condition suggests wide-spread changes within the Chesapeake Bay Watershed, USA Long-term predictive modeling of stream condition suggests wide-spread changes within the Chesapeake Bay Watershed, USA
Stream ecosystems worldwide face ongoing degradation, underscoring the urgent need for conservation and restoration. Regional analyses of stream condition have been limited by sparse spatial and temporal data, particularly at long time scales. To address this gap, we used observed data to predict annual biological condition for 360,893 small, nontidal stream reaches in the Chesapeake Bay...
Sediment response to stream restoration in an agricultural watershed Sediment response to stream restoration in an agricultural watershed
Despite widespread implementation of stream restoration there is limited research of its effectiveness in impaired agricultural settings. To quantify the effects of stream restoration on sediment load, we investigated erosion and deposition along 9 stream reach sites (4 restored, 4 unrestored, and 1 downstream) in Turtle Creek, Pennsylvania, United States - a representative agricultural...
Loss and transformation of coastal wetlands due to global change in the conterminous United States: Past, present, and future Loss and transformation of coastal wetlands due to global change in the conterminous United States: Past, present, and future
Coastal wetlands are being transformed by global change, impacting the ecological and societal benefits provided by these ecosystems. Synthesizing knowledge of historical and expected future transformations in coastal wetlands can help inform forward-looking planning and stewardship efforts. Here, we review anticipated future ecological transformations in coastal wetlands of the...

Connecting Conservation Practices to Local Stream Health in the Chesapeake Bay Watershed
Osprey (Pandion haliaetus) Population and the Availability of Menhaden (Brevoortia tyrannus) as Their Food Source in Chesapeake Bay: Historical and Present-day Comparison
USGS is collaborating with many biologists in analysis of data on osprey ( Pandion haliaetus) and their prey (menhaden, Brevoortia tyrannus, and other species of fish) in the middle and lower Chesapeake Bay and its tributaries. The data compiled and collected will help determine if a lack of menhaden or other environmental factors are affecting osprey reproductive success in portions of the...
Evaluating the Effects of Stream-Restoration Practices in an Impaired Agricultural System
Stream-restoration practices are widely used throughout the Chesapeake Bay watershed to improve stream health and function, but research into their effectiveness is limited in agricultural settings. A study in Turtle Creek, Pennsylvania, suggests that stream-restoration practices can significantly reduce streambank erosion and enhance floodplain deposition, changes that can reduce in-stream...
