Project
Information
Lock and Dam 5, like all navigation facilities on the Allegheny
River, consists of a single lock chamber and a fixed crest dam.
This type of dam is basically a concrete weir or wall across the
river which keeps the river channel upriver of the project deep
enough for navigation -- about 9 feet or more. Water which flows
over this type of dam cannot be controlled locally. Consequently,
it cannot provide any control over flood waters. An incidental benefit
derived from the pool formed by the dam is the availability of a
source of municipal and industrial water.
