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:
“To succeed in the other trades, capacity must be shown; in the law, concealment of it will do.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.”
—Elaine Heffner (20th century)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
