Pilot project planned to dredge Conowingo sediments

Declaring the sediment buildup behind Conowingo Dam a growing threat to the Chesapeake Bay, Maryland Gov. Larry Hogan announced Tuesday a pilot project to dredge up a tiny portion of the accumulated silt and sand.

Speaking at a press conference at the dam, Hogan said the state later this month would issue a request for proposals to dredge 25,000 cubic yards of sediment by next spring from the reservoir upstream of the hydroelectric facility on the Susquehanna River.

The intent, he said, is to pin down what it would cost to dredge massive quantities of sediment from the Conowingo “pond,” as the reservoir is called, and to find out if there are viable markets for reusing the material. He said that he hoped the project would help the state determine whether large-scale dredging is feasible - even though an ealier study concluded that dredging the built-up sediment would be costly and provide little overall benefit to the Bay.

About Energy

Energy production has had a profound influence on the Chesapeake and its tributaries since European settlement. Settlers built thousands of dams across streams and rivers to provide power for mills and industry. More modern dams create hydroelectric power, but dramatically affect river ecosystems and close them to fish migration.

Combustion of fossil fuels is a major source of pollution to the Chesapeake, and activities such as drilling in the Marcellus Shale can affect stream health and permanently alter terrestrial habitats.
