Capacity
Chickamauga Dam is a concrete gravity-type dam 5,800 feet (1,800 m) long and 129 feet (39 m) high. Its hydroelectric generating capacity is 160 megawatts. The dam has 18 spillway bays with a combined discharge of 470,000 cubic feet per second (13,000 m3/s).
A 60-by-360-foot (18 by 110 m) navigation lock allows barges and other boats to travel past the dam, raising or lowering vessels 53 feet (16 m) between Chickamauga and Nickajack reservoirs. Because the concrete of the original lock has deteriorated due to "concrete growth" caused by chemical reactions between its constituent cement and rock aggregate, a $375 million project to replace the lock began in 2003. The new 110-by-660-foot (34 by 200 m) lock was scheduled to be completed by 2014.

Famous quotes containing the word capacity:
“The frequent failure of men to cultivate their capacity for listening has a profound impact on their capacity for parenting, for it is mothers more than fathers who are most likely to still their own voices so they may hear and draw out the voices of their children.”
—Mary Field Belenky (20th century)
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“The capacity to give one’s attention to a sufferer is a very rare and difficult thing; it is almost a miracle; it is a miracle. Nearly all those who think they have this capacity do not possess it. Warmth of heart, impulsiveness, pity are not enough.”
—Simone Weil (1909–1943)
