Museums To-Go: The Croton Aqueduct

This lithograph of the D reservoir in Carmel was taken as part of a progress report on the Croton Aqueduct and would be presented to the Aqueduct Commissioners between 1887 and 1895.

The Croton Aqueduct was designed to bring fresh water from the Croton River to the citizens of New York City, who had been suffering epidemics of Cholera and Yellow Fever due in part to lack of access to fresh water. Some of New York City’s wealthier residents would have fresh water delivered to them by a company now known as Chase Manhattan. The rest of the city’s population, however, would have to rely on dangerous, polluted water.

On June 22, 1842, after five years of construction, the Croton Aqueduct brought fresh water into New York City for the first time. It took a total of 22 hours to bring the water 41 miles from the Croton River into Manhattan. The new freshwater source drastically improved public hygiene. Baths and running water were being built in the private homes of wealthy New Yorkers, and public bathing facilities were constructed for the masses.

Although this aqueduct is not in use today, its successor, the New Croton Aqueduct which was put into service in 1890, still serves 10% of Manhattan’s population.

WARNING! Be careful about using the Friends of the Old Croton Aqueduct online store. On August 2, 2021 I purchased two maps from the Friends of the Old Croton Aqueduct website. Never received them!
Today, walking the trail between Irvington and Lyndhurst, I found a small brass(?) plate. If you believe it is yours, please describe. Of course, I will return the plate upon receiving a matching description. The plate does not appear to be antique or of much value, but I expect it would be a nuisance to replace.
I just realized I am working on( fiber art piece that has) Ventilator shaft # 8 ( on the Aqueduct trail)
Chat Conversation Start 1.7K people like this Park 11:21 AM What can we do about the littering on the OCA trails? Now that more people are home and with many discovering the trails I have seen more trash on the trails then usual. The ventilator #19 is located behind my backyard and people leave trash near and on it daily. The Untermeyer park is about a 5min walk from me and they have a trash can behind the welcome sign easy to reach from the gate even if the doors are locked. Last year one home south of mine off the trail fence caught on fire due to a cigarette.😔😥
Thank YOU to Sara and Pete, from the Guides Association Of New York City Our visit to the New Dam and the 1842 Tunnel was part of a great day. You are both top notch guides. All the way home and on social media, the members are still taking about our day. It was wonderful, educational and a pleasure to visit
A Thank you to Pete and Sara, at Friends of the Old Croton Aqueduct That is from the Guides Association Of New York City. We enjoyed our visit, with 37 enthusiastic members. We visited the Ossining Weir and the Croton Dam. Pete and Sara were great!
With 60+ degree weather in NYC this weekend, my brother, his girls and I made a wonderful decision to visit the Old Croton Aqueduct Historic State Park in Dobbs Ferry, NY on Saturday. It's a main access point to an easy 26-mile scenic walking/hiking/biking trail atop the Old Croton Aqueduct. We parked and started at the 1857-built Keeper's House which is free, open to the public, where Mavis Cain, President of Friends of the Old Croton Aqueduct taught us much about the history of the Old Croton Aqueduct, which went off-line and stopped supplying water to NYC in 1955. Constructed from 1837 to 1842 to supply Manhattan with fresh water, the Old Croton Aqueduct lies buried in a man-made sloping dirt berm. So, the trail runs right on top of the berm and therefore, the old aqueduct. The scenic trail runs atop the northernmost 26-miles, although the aqueduct itself is 41 miles long, and carried water by gravity from the source (Croton River) to Manhattan. The height of the gravity-fed aqueduct drops 1/4" per 100' (13 inches per mile), taking 22 hours for gravity to move the water down the 41 miles at a speed of 1.86 miles per hour to reach Manhattan. It was built because local water sources for Manhattan had become polluted and inadequate for the growing population – which was just 319,000 people living in Manhattan at the time (1842). There was no plumbing for fresh water, no wastewater or sewer systems. Wealthy people had water delivered to them by the Manhattan Company, a water company which eventually became Chase Manhattan bank. Much of the above info is from Wikipedia. We walked the trail about 3 miles. Many empty bird nests and squirrels in the trees along the way. A good day was had by all. We hope to return again once spring has sprung!
We loved the nature, history & unique facts about Ossining & stories about the aqueduct past & present that was exceptionally led by Friends of the Old Croton Aqueduct Star ⭐️ tour guide Leslie! It was called Weirs to Beers 🍻 & ended with Sing Sing Kills brewery stop in Ossining! We will definitely go again. I couldn’t believe how three hours in Ossining could be so great & free activity!
Does anyone have a gpx file or map of the section of the rtoue in NYC? Trying to plan a run of the whole 41 miles.
