The Washington Aqueduct, carrying drinking water to the nation’s capital but running mostly through Montgomery County from Great Falls, was a technological marvel when completed 160 years ago in 1864. After all that time of continuous service, it is currently undergoing a major rehabilitation. Through current and historical photos, Ralph Buglass will relate the fascinating history of this project, now a National Landmark, and look at its equally fascinating chief engineer, Montgomery Meigs, who was also Quartermaster General of the U.S. Army during the Civil War. In charge of all the troop logistics, Meigs has been described as “second only to General Ulysses Grant” in winning the war for the Union.
