Spotlight on sediments: How is the Chesapeake Bay affected by storm flows from the Conowingo Reservoir?
Looks can be deceiving. Whether you’re standing by the dam watching the brown roaring water rush into Chesapeake Bay or recounting salellite images of the massive sediment plume churned up by Tropical Storm Lee in 2011, you’re all but certain of one thing: sediment flowing over Maryland’s Conowingo Dam—the Susquehanna River’s last stop before Chesapeake Bay—has to be the cause of recent declines in Bay water quality. But results from a three-year feasibility study of sediment moving through the Lower Susquehanna watershed and Conowingo Reservoir suggest that nutrients—mainly nitrogen and phosphorous—from upstream of the Conowingo are the real problem, not the clay and sand washing into the Bay.
