The Conowingo Dam

The Conowingo Dam

The Conowingo Dam straddles the Susquehanna River near the mouth of the Chesapeake Bay in Maryland, and its hydroelectric plant powers 160,000 homes and businesses. Over nearly a century, sediment and nutrients have built up in the reservoir behind the dam, and now during major storms those pollutants pour into the Chesapeake. Some, including Maryland’s Governor Larry Hogan, believe dredging is the solution; others say that’s a distraction from watershed pollution upriver. We explore the issues.
