This photograph of the New Croton Dam was published in the “Rotogravure Picture Section” of the Sunday, December 14, 1919 issue of the New York Times with the caption:
Niagara Falls by Man’s Own Hand: For the first time in fourteen years water is flowing over the huge dam of the Croton Reservoir at the estimated rate of 2,000,000,000 gallons a day, the vast tide dropping to the Croton River, 150 feet below.
The photo was taken by Underwood & Underwood, a pioneer in the field of news bureau photography.

With the help of your website, I have identified four photographs as being taken in the 1890s during construction of the New Croton Dam. How may I post scans of these photos for discussion?
Hi. I’d love to see them. Can you upload them online to a service like Google photos and send me a link? Are these actual prints you own?
