This view of Unit #1 in Powerhouse #1 shows how each generator was flanked by two Pelton waterwheels. This was done to equalize the tremendous forces placed on the common shaft joining the waterwheels to the generator. At this time, Big Creek's two powerhouses employed the largest Pelton-style waterwheels ever built.
