Dams under construction. Watts Bar Dam, shown here under construction, has a semi-outdoors type powerhouse with an enormous gantry crane (to the right of the picture) for installation and removal of units. The project is further distinguished by a control building which is entirely removed from the hydro plant, being located some 120 feet higher on top of a steep cliff and with direct connection to the switchyard behind. The windowless left wing of the control building houses the control room; the tower-like structure in the back accomodates air conditioning, restrooms, etc. The glass wall, upper level, contains the reception room with a broad semi-circular overlook terrace, the story below the terrace devoted to offices
Dams under construction. This rather curiously shaped stairway give access from the control building of the Cherokee hydro plant ot the switchyard which is high up on the steep hillside. The stair was laid out in a V-shape to gain additional length for the total rise. Grading and planting are unfinished
