Congrats all go to just Elisa this time, for providing the correct answer to yesterday’s quiz.
Yes, this is one of the few visible sections of the Washington Aqueduct system, which can be seen in and around the C&O Canal path from Great Falls, Maryland, down to Old Angler’s Inn. The section I showcased in yesterday’s post and this one is about a mile north of the parking lot near Old Angler’s Inn, and on the trail to the east of the canal proper — not the towpath itself. Because of this isolation, only 5-10 percent of the total pedestrian traffic through the general area ever passes this structure, and fewer even realize it’s something different from the C&O Canal infrastructure.
Sadly, this structure is being ravaged by time. The concrete and metal access steps on both sides of it have disintegrated; just the metal supports remain. The concrete of the main structure is gradually eroding with each freeze and thaw cycle, and doesn’t look like it’s been maintained in decades. Yet it still produces some 300 million gallons of filtered water every day and serves over 1 million customers throughout the Washington, DC, region.
