10 Forgotten Reservoirs and Aqueducts for Urban Explorers to Discover

With the advancement of technology and infrastructure, many reservoirs and aqueducts built in the past have been forgotten. These structures were once used to supply water to cities, towns, and farmlands but now remain abandoned. Here are ten forgotten reservoirs and aqueducts that urban explorers can discover.
1. The Catskill Aqueduct – This 120-mile-long aqueduct was built in 1917 to bring drinking water from the Catskill Mountains to New York City. Today, parts of it have been abandoned and are accessible for exploration.
2. The Old Croton Aqueduct – Built-in 1842, this aqueduct brought fresh water to New York City until it was decommissioned in 1955. Today, sections of it are open for walking tours.
3. Hetch Hetchy Reservoir – Located within Yosemite National Park in California, this reservoir was created by damming the Tuolumne River in 1923. It supplies drinking water to San Francisco but is also a popular hiking destination.
4. Ashokan Reservoir – Another Catskill Mountain reservoir that supplies drinking water to New York City, this one has a scenic walkway on top of its dam that offers stunning views of the surrounding mountains.
5. Devil’s Gate Dam and Reservoir – Located in Pasadena, California, this dam was completed in 1920 and provided local residents with drinking water for over fifty years before being decommissioned.

While these forgotten reservoirs and aqueducts are no longer serving their original purpose, they offer a glimpse into our past infrastructure and history. Urban explorers can discover some amazing sights while also learning about how we have managed our precious water resources over time.
