Nutrient pollution in Bay’s 3 largest rivers trending downward
"The Chesapeake Bay’s three largest rivers — the Susquehanna, Potomac and James — are showing long-term reductions in nutrient pollution, according to data recently released by the U.S. Geological Survey.
The trends are particularly notable in the Susquehanna, where USGS monitoring has shown steady improvements in recent years — despite concerns about the impact of Conowingo Dam and complaints that Pennsylvania, which holds most of the river’s watershed, is not doing enough to help the Bay. USGS scientists say they are working to better understand the reasons for that trend."
The USGS summary of these results can be found at Updated 2020 Nutrient and Sediment Trends for the Nine Major Rivers Entering the Chesapeake Bay.
