Pelton Water Wheel at Nisqually Dam (ca. 1942)

s-l1600As I write this, the image here is for sale on Ebay. The information on the photo reads: “Photograph shows a workman standing next to a Pelton water wheel case for La Grande Dam on the Nisqually River in Washington.”

To see how one of Lester Pelton’s water wheels operates, you can check out this YouTube video. 

Lester Pelton, known by some as the father of hydroelectric power, died in 1908, so he didn’t get a chance to see this particular water wheel in operation.
