16 U.S.C. § 804 — Project works affecting navigable waters; requirements insertable in license

If a dam or other project work will be built across, along, or in navigable United States waters, the commission may include one or more of these license requirements when it considers them reasonably necessary for present or future navigation and consistent with a reasonable investment cost to the licensee: (a) The licensee must, as needed to preserve or improve navigation, build all or part of locks, booms, sluices, or other navigation structures connected with the dam, at no cost to the United States, using plans and specifications approved by the Chief of Engineers and the Army Secretary and made part of the license. (b) If the licensee does not build those navigation structures as part of the original construction, then when the United States wants to complete them, the licensee must give the United States, free of charge, the needed land, rights-of-way, and passage through its dams or other structures, and must allow the pool control needed to complete the facilities. (c) The licensee must give the United States, free of charge, power to operate the navigation facilities, whether the licensee or the United States built them.
