On October 27, 2021, we drove to the Croton Gorge to view the dam. Considering the very heavy rain we had over the prior two days, we expected a voluminous amount of water going over the dam.

Our guess was correct!

About a quarter of a mile before we reached the dam, we could hear a thundrous noise. As we approached the bridge, the noise of rushing water was very loud and the spray was like rain.

Note the small tree on the dam's spillway.

The New York City Department of Environmental Protection closed the public walkway atop New Croton Dam for five days earlier this month, creating a safe work zone for an inspection of the dam.

The closure allowed a team of rope-access technicians to rappell down the face of the dam and inspect the stones that were used to build the structure 115 years ago. It was the largest dam in the world when it was completed in 1905.
