This 1922 map shows the proposed ultimate development of the Big Creek Project to a size even larger than that first envisioned by John Eastwood. Still later plans added more powerhouses on the South Fork of the San Joaquin, but none were built before the depression ended work. Today, the Balsam Meadows Plant is near the site of old Powerhouse #5. Pg. 103.

This view of Unit #1 in Powerhouse #1 shows how each generator was flanked by two Pelton waterwheels
Visual Materials
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.
