Jim Woodruff Dam - Chattahoochee, Florida, USA - Hydroelectric Power Stations on Waymarking.com

Jim Woodruff Dam is a hydroelectric dam on the Apalachicola River, about 1,000 feet (300 m) south of that river's origin at the confluence of the Flint and Chattahoochee Rivers.

The dam impounds Lake Seminole on the common border of Florida and Georgia. The dam is named in honor of James W. Woodruff, Sr., a Georgia businessman who spearheaded the development of the Apalachicola-Chattahoochee-Flint Project.

Normal pool for Lake Seminole is 77 feet MSL, and the lake covers 37,500 acres at that level. The GA/FL state line crosses the eastern side of the dam. The lock is 82 feet wide by 450 feet long, with a maximum lift of 33 feet. The ACF (Apalachicola-Chattahoochee-Flint) system is navigable to Columbus on the Chattahoochee River and to Bainbridge on the Flint River. The powerhouse has three units rated at a total of 36 Megawatts at normal head of 30.5 feet, or 6 Megawatts at minimum head of 9 feet. Hydraulic capacity is 18,300 cfs at normal levels. This dam does not have Tainter gates. These are called Vertical lift split leaf gates; there are 16 of them and they are 40 feet wide by 30.5 feet high. There are two gantry cranes to operate the gates; and one of those is also used to operate the intake gates to the powerhouse as well.

Besides the gated spillway at 766 feet long, there is a fixed crest spillway (elev 79 feet) for another 1634 feet, and an earthen overflow dike (elev 85 feet) at 2,130 feet. According to the pertinent data, the 100 year flood puts the lock underwater, the "biblical" flood puts the whole project under water. The "spillway design flood" has the tailwater elevation at 96.73 feet, and the headwater elevation at 96.1 feet.

The groundbreaking ceremony took place on October 1, 1947, it was dedicated on March 22, 1957.
