Dams and locks are used to facilitate the transport of goods and materials. The U.S. Army Corps of Engineers maintains navigation projects in 41 states to support the transport of freight on inland waterways, including 275 locks and 926 harbors.
“A navigation dam is similar to most other dams in that its intended purpose is to impound water. However, it is usually designed so that the water surface upstream of the dam is of such elevation that there will be sufficient depth for navigating a relatively long distance upstream from the dam without having to go through another lock or to dredge excessively”.[1]
