A Century in Contrast: Then & Now at the Conowingo Dam
As part of our ongoing “Then & Now” series, we’re journeying through time using photographs from Lewis Reed’s remarkable photo collection. These powerful comparisons highlight how much, and sometimes how little, the world around us has changed. In this installment, we turn our lens to the Conowingo Dam, where echoes of the past still linger in the present. Step back in time and see how this historic site has evolved over the past 100 years.
Conowingo Dam (THEN): The Conowingo Dam, completed in 1928, is a large hydroelectric dam on the Susquehanna River in Maryland, known for its role in power generation and its impact on the Chesapeake Bay. When completed, it was the second-largest hydroelectric project by power output in the United States, after Niagara Falls.

Conowingo Dam (NOW): Today, the Conowingo Dam is operated by the Susquehanna Electric Company, a part of Constellation Energy. The dam is one of the most popular destinations in the United States for seeing bald eagles. While the surrounding area is home to dozens of the eagles year-round, upwards of 200 more will migrate from places like New York and Canada, where lakes and rivers freeze over in the winter and limit fishing opportunities. Their numbers typically peak from November to January, with the eagles taking advantage of the dam’s turbines stunning fish swimming downriver to make for easy hunting. Once a fish is caught, eagles will often battle midair for it, and the spectacle attracts bird photographers from all over the world.
