Search 16 U.S.C. § 805 : US Code - Section 805: Participation by Government in costs of locks, etc.

Whenever application is filed for a project hereunder involving
navigable waters of the United States, and the commission shall
find upon investigation that the needs of navigation require the
construction of a lock or locks or other navigation structures, and
that such structures cannot, consistent with a reasonable
investment cost to the applicant, be provided in the manner
specified in subsection (a) of section 804 of this title, the
commission may grant the application with the provision to be
expressed in the license that the licensee will install the
necessary navigation structures if the Government fails to make
provision therefor within a time to be fixed in the license and
cause a report upon such project to be prepared, with estimates of
cost of the power development and of the navigation structures, and
shall submit such report to Congress with such recommendations as
it deems appropriate concerning the participation of the United
States in the cost of construction of such navigation structures.
