New Croton Dam Construction, circa 1902

We recently acquired a great set of photographs showing the New Croton Dam under construction. The images are particularly exciting because they include some rare views of the construction site and one of the soon-to-be submerged Old Croton Dam. Based on the state of completion of the dam we think these were taken circa 1902.1

The images appear to document a visit to the site by “Mr. John Fish,” who can be seen in several photographs. Who was Mr. Fish and why was his visit photographed? Why were the photos laboriously labelled on the negatives when a simple inscription on the back of the print or on a scrapbook page would have sufficed?2

We don’t know. We speculate that Fish may have been involved in the construction as a subcontractor but so far a search of online and offline sources has turned up nothing. If you have any information please send us an email.

The scanned images below have been adjusted in Photoshop to increase contrast and bring out details. The actual prints are lighter, either due to age, overexposure when the photos were taken or printed—or both. We have cropped and enlarged sections of the images to bring out glorious details.

  1. Many thanks to Tom Tarnowsky, Friends of the Old Croton Aqueduct, and Carl Oechsner, Croton Friends of History, for their help in analyzing these photographs. ↩︎
  2. The text labels in the photos were added to the negatives in the darkroom so they would appear on every print. To be readable when the images were printed the labels needed to be written or applied in reverse—a tricky thing to do in a darkroom—which is why some of the letters are incorrectly reversed on the prints. Because the text labels in several of the photos are cut off it appears these prints were trimmed down, though it could also have been a mistake when the images were printed. None of the prints have inscriptions on the back and the seller was unable to provide any additional information. ↩︎

Here’s a nice view of the nearly-completed New Croton Dam (also known as the Cornell Dam) circa 1907. We can roughly date the image from the state of construction and the card itself because it’s an “undivided back” postcard, issued during the period from 1901 to 1907. Until 1907 only the mailing address could be written on the back of the card.

This card was published by William Terhune in “Ossining on Hudson” and printed in Germany.
