This reservoir was built in 1906 as an extension of the New Croton aqueduct as part of the New York City water supply system. After being closed and reopened, in November 2015 the Department of Environmental Protection started offering public tours of the perimeter and the central walkway.
Unfortunately, there isn't much to do, here. We were told that this is the last place drinking water gets before going through the purification system, so it's heavily guarded and thoroughly fenced. NYPD officers patrol the whole perimeter of the reservoir, some on SUVs, some on bikes, some on foot. A double set of high fences rings the body of water, with cameras and mini control towers checking the situation.
On set dates, open houses allow visitors to walk along the walkway passing through the middle of the reservoir, but you must leave bags along with phones with (rude) employees, who tell you to drop them on the grass, and clarify that they "are not responsible for them". No photography is allowed inside the reservoir.
Quite frankly, it's not worth. Unless you go inside, there's only one spot from the southern end that gives you a somehow open view of the reservoir, and it's nothing special.
If you are passionate about the water system in New York City, and want to get an idea of where the water we drink is temporarily stored, this might be an interesting spot to visit. However, if you are coming here looking for scenery, don't even bother, because the path around the reservoir offers almost no view of the water. read more
