Editing Port Deposit, Maryland (section)

===Damming the Susquehanna===
The Susquehanna River drops {{convert|167|ft|m}} as it passes through the region above Port Deposit, as it cuts through the hard rock of the region. This characteristic, which had long been good for Port Deposit, also attracted power companies in the boom period after [[World War I]]. The [[Conowingo Dam]], built in 1927, permanently changed the character of the town by terminating all river traffic and decimating what was left of the shad and herring fishery which was once found there. Port Deposit benefited from the dam as well; destructive accumulations of ice (referred to as ice gouges) no longer accumulated in the Conowingo Rapids or passed through Port Deposit,<ref name="B" /> as it had to terrible effect in 1907.
