Chickamauga Dam and powerhouse. View of generator hall, looking towards reception room end. Upper row of three large windows is overlook for reception room. Three windows beneath are those of control room (compare with K 2313). Balcony for communication and view in front of control room windows. Roof is carried by rigid steel arches which spring from crane rail level; steel purlins, exposed precast concrete slab. Windows of hall are glass brick for insulation. Translucent plastic discs suspended from standard highboy lighting units conceal view or direct reflection of filaments and reflect spill light onto ceiling, thus generally brightening the space. Floor is ceramic tile; walls, glazed structural tile up to crame rail, exposed concrete above

Chickamauga Dam and powerhouse. Main control room and partial view of balcony in front of it (compare with end wall in K 2304). Large glass panels permit observation by visitors and view of plant by control room operators. Ceiling of control room is assymmetric barrel vault with acoustic tile surface; all light is indirect from reflectors above low soffit along front of room. In more recent installations, control equipment is gray instead of black to reduce eye fatigue by lessening contrast

Chickamauga Dam and powerhouse. Hall off reception room which gives access to a good view of the tailrace through a window, thus making it possible for visitors to observe all essential parts of the project (generator hall, switchyard, reservoir, tailrace) from either the reception room or the hall. It also gives access to the elevator, the main stair, toilets, and to a promenade roof deck over the lower electrical bay of the powerhouse (foor at end). The decreasing height of the ceiling was necessitated by structural considerations ad was exploited for effect. Floor is terrazzo; walls, glazed structural tile; ceiling, plaster

Chickamauga Dam and powerhouse. Reception room, looking upstream. Glass wall at end of room overlooks reservoir; platform raised two steps for better view across deck of dam. Glass wall at left overlooks generator hall; doors at right offer view of switchyard. Niche beyond set of doors, empty at the time photograph was taken, has since been filled in with the graphic display for which it was intended. Floor is terrazzo in large squares; lower part of wall, marble from nearby quarries; everything above is plaster

label_outline Explore Three Windows, Control Room, Chickamauga Dam

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

Power and conservation. Chickamauga Dam, Tennessee Valley Authority (TVA). Insulators and bus wires in the switchyard of the TVA's Chickamauga Dam, located near Chattanooga, 471 miles above the mouth of the Tennessee River. The dam has an authorized power installation of 81,000 kilowatts, which can be increased to a possible ultimate of 108,000 kilowatts. The reservoir at the dam adds 377,000 acre feet of water to controlled storage on the Tennessee River system. The power that passes through this switchyard serves many useful domestic, agricultural and industrial uses
