Chesapeake Bay Activities
Assessing Effects of Sea-level Rise on Upstream Ecosystem Conditions
A synthesis addresses what is known about the ecosystem consequences of freshwater tides extending upstream into formerly nontidal rivers.Science Summary
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. See our Science page to learn about our themes and topics being addressed.

Bay Journal - Karl Blankenship - 1/7/2019
For the Chesapeake, 2018 was a year of mud, trash, and sewage as unrelenting rainfall washed across its vast watershed, sending unusually high amounts of freshwater runoff into the Bay month after month.

Controls of the spatial variability of denitrification potential in nontidal floodplains of the Chesapeake Bay watershed, USA
Identifying floodplains with high rates of denitrification will help prioritize restoration projects for the removal of nitrogen. Currently, relationships of denitrification with hydrogeomorphic, physiographic, and climate (i.e., largescale) characteristics of floodplains are relatively unknown, even though these...Korol, Alicia R.; Noe, Gregory B.; Ahn, Changwoo
Agricultural conservation practice implementation in the Chesapeake Bay watershed supported by the U.S. Department of Agriculture
The U.S. Department of Agriculture (USDA) provides cost-share funding and technical assistance to support the implementation of agricultural conservation practices on farms throughout the Chesapeake Bay watershed. Conservation implementation has been substantial in the time period for which digital records are available (from 2007 through 2017)....Hively, W. Dean; Devereux, Olivia H.; Keisman, Jennifer L.D.
Bank‐derived material dominates fluvial sediment in a suburban Chesapeake Bay watershed
Excess fine sediment is a leading cause of ecological degradation within the Chesapeake Bay watershed. To effectively target sediment mitigation measures, it is necessary to identify and quantify the delivery of sediment sources to local waterbodies.This study examines the contributions of sediment sources within Upper Difficult Run, a...Cashman, Matthew J.; Gellis, Allen; Gorman Sanisaca, Lillian; Noe, Gregory B.; Cogliandro, Vanessa; Baker, Anna
