Bird’s Eye Views of the Croton Aqueduct, 1879-1887

Here are two priceless “bird’s eye” views of the Croton Aqueduct, made eight years apart during the period when New York City was rapidly outgrowing the capacity of what we now call the Old Croton Aqueduct.

These aerial and ground photographs were taken by Jack Boucher in 1978 and are now part of the Historic American Engineering Record collection of the Library of Congress. The collection includes a large number of photographs and plans documenting the original Croton Dam, the New Croton Dam and the entire aqueduct system.

Driving to the Dam, 1912

This is an often photographed view of the New Croton Dam, but this particular image from 1912 captured an automobile driving along the road which once ran across what is now the Old Croton Aqueduct Trail. For an equally romantic image of "driving" out to the Dam, see this earlier post.

New Croton Dam Construction Plan, 1898

By any measure, the New Croton Dam is an engineering marvel. For 14 years (from 1892 to 1906) 1,500 men used more than 500 pieces of heavy machinery, 745,000 barrels of cement, 100,000 tons of coal and an incalculable quantity of locally quarried stone to build the dam.  How did they do it? These images … Continue reading New Croton Dam Construction Plan, 1898
