Doug Moyer is the Associate Director for Studies and a Supervisory Hydrologist with the U.S. Geological Survey's Virginia and West Virginia Water Science Center in Richmond, VA.
Doug has been involved with a wide variety of USGS water-resources investigations throughout the Chesapeake Bay region since 1998. A primary focus of his work has been on monitoring and modeling the fate and transport of nutrients and suspended sediment across multiple watershed scales throughout Virginia and the Chesapeake Bay watershed.

USGS revises 2020 nontidal load and trend results
Issue: The USGS has revised loads and trends through 2020 from monitoring stations in the Chesapeake Bay Program (CBP) Nontidal Network (NTN). The original release of the results was in July 2022. During a process to implement a new software package for the next update of NTN data, the USGS discovered some questionable data values. Most of the questionable values were related to a coding...
Tracking Status and Trends in Seven Key Indicators of River and Stream Condition in the Chesapeake Bay Watershed
Identifying and tracking the status of, and trends in, stream health within the Chesapeake Bay watershed is essential to understanding the past, present, and future trajectory of the watershed’s resources and ecological condition. A team of USGS ecosystem scientists is meeting this need with an initiative to track the status of, and trends in, key indicators of the health of non-tidal freshwater...
Updated 2020 Nutrient and Suspended-Sediment Trends for the Nine Major Rivers Entering the Chesapeake Bay
Issue: The amount of nutrients and suspended sediment entering the Chesapeake Bay affect water-quality conditions in tidal waters. Excess nutrients contribute to algal blooms that lower the oxygen levels in tidal waters that are important for fish and shellfish. The algal blooms, along with suspended sediment, also decrease visibility in shallow waters for submerged aquatic grasses. The grasses...
USGS develops tool to further examine nutrient and sediment trends in the Chesapeake Bay Watershed
The U.S. Geological Survey (USGS) has developed the nontidal network mapper to share the short-term (2009-2018) water-year nutrient and suspended-sediment load and trend results for the Chesapeake Bay Program’s (CBP) non-tidal network (NTN). The network is a cooperative effort by USGS, the U.S. Environmental Protection Agency (USEPA), and agencies in the states of the Chesapeake watershed and the...
USGS updates trends for nutrients and sediment in the Chesapeake Bay Watershed
Issue: The Chesapeake Bay Program (CBP) nontidal network (NTN) consists of more than 100 stations throughout the Chesapeake Bay watershed. Monitoring of nutrients, sediment, and flow is conducted to provide estimates of loads and trends in the watershed. The CBP uses the results to focus restoration strategies and track progress towards meeting nutrients and suspended-sediment reduction goals.
Chesapeake Bay Estimated Streamflow: WEBSITE HISTORY
by Brad Garner, Hydrologist USGSThis website originated as a dynamic web application (hereafter, simply webapp). That is, content such as data and graphs, were generated "on-the-fly" as requests were made by web-browser clients. This was made possible by automating the methods of Bue (1968), and by using dynamic web-content software technology.Beginning in 2019 the original dynamic web application...
Freshwater Flow into Chesapeake Bay
Explore resources here describing estimates of freshwater flow entering Chesapeake Bay. The health of the Chesapeake Bay is greatly affected by freshwater flow from rivers draining its watershed. The amount of freshwater flow (also called streamflow) will: • Change salinity levels in the Bay, which affect oysters, crabs, and finfish. • Influence the amounts of nutrients, sediment, and contaminants...
Chesapeake Bay Estimated Streamflow: METHODS
Methods for Estimating Streamflow to Chesapeake BayThe following is a description of how data presented on the website "Chesapeake Bay Estimated Streamflow" are computed.Essentially, the methodology was published more than 51 years ago, and has been adapted for use in modern automated computing systems. Approaches for summarizing data and describing it using statistics follow standard practices...
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 safe...
Monitoring High-Priority Stream Crossings Along Proposed Natural Gas Pipeline Routes
The U.S. Geological Survey (USGS), in cooperation with the Virginia Department of Environmental Quality (DEQ), is monitoring the water quality of multiple high-priority streams where natural gas pipeline crossings have been proposed. The purpose of the monitoring effort is to collect baseline water-quality data and, if the pipeline construction is approved, to monitor water quality in these...
Chesapeake Bay Water-Quality Loads and Trends
Explore resources here describing water-quality load and trend results for nontidal rivers of the Chesapeake Bay watershed. The health of the Chesapeake Bay is largely driven by changes in streamflow and the amount of pollution it contains. Runoff in the Chesapeake Bay watershed carries pollutants, such as nutrients and sediments, to rivers and streams that drain to the Bay. Scientists use...
