Chesapeake Bay Activities Newsletter November-December 2020
The USGS provides research and monitoring to better understand and restore the Chesapeake Bay and its watershed. Our technical reports and journal articles, which we translate into science summaries, provide the findings used by federal, state, and local decisionmakers to inform restoration and conservation decisions. Here are some recent highlights.

Assessing native fish restoration potential in Catoctin Mountain Park
Biological conservation is a fundamental purpose of the National Park system, and Catoctin Mountain Park (CATO) supports high-quality habitat for native fishes in the headwaters of the Chesapeake Bay watershed in eastern North America. However, native Blue Ridge sculpin (Cottus caeruleomentum) have been extirpated in Big Hunting Creek above Cunningham Falls in CATO. Prior research indicates that i
Meeting the challenge: U.S. Geological Survey North Atlantic and Appalachian Region fiscal year 2020 in review
The utilization, preservation, and conservation of the Nation’s resources requires well-informed management decisions. The North Atlantic and Appalachian Region (NAAR) of the U.S. Geological Survey (USGS) supports science-based decision making for Federal, State, and local policymakers to meet the challenges of today and into the future. The science centers in the NAAR have well-deserved reputatio
Data-sharing agreement renewed to evaluate conservations practices and water quality in the Chesapeake Watershed
Issue: The U.S. Geological Survey (USGS) and the Natural Resources Conservation Service (NRCS) have a mutual interest in meeting the goals of the Chesapeake Bay Watershed Agreement, and in determining the benefits and challenges of agricultural conservation practices on water-quality patterns. Understanding the sources of nutrients and sediment and how these nutrients move into streams and groundwater is critical to design effective nutrient management and erosion control strategies.

Spatial and temporal patterns in streamflow, water chemistry, and aquatic macroinvertebrates of selected streams in Fairfax County, Virginia, 2007–18
Urbanization substantially alters the landscape in ways that can impact stream hydrology, water chemistry, and the health of aquatic communities. Stormwater best management practices (BMPs) are the primary tools used to mitigate the effects of urban stressors such as increased runoff, decreased baseflow, and increased nutrient and sediment transport. To date, Fairfax County Virginia’s stormwater m
