authorization, water supply, school facilities, and railroad
bridges altered at federal expense.m In addition to author-
izing particular types of work, these laws also govern the
related aspects of prosecution of projects. Also applicable
here are the pre-1917 laws relating to the prosecution of
navigation improvements, already discussed.a Apart from
these two groups of statutes, Congress has enacted no legisla-
tion specifically governing the prosecution of flood-control
Operation of Projects
In the discussion of laws affecting the operation of naviga-
tion projects, we summarized those parts of the Act of Decem-
ber'22, 1944, which relate to the use of dams and reservoirs for
navigation, power, water supply, iirigation, and recreation.13
Similarly, reference was there made to the provisions of
1946 legislation concerning wildlife resourcesn"' So also as to
the provisions of the Act of July 29,1946, regarding the possible
use of dams as foundations for bridges.u All of those pro-
visions apply with like force to the operation of flood-control
projects. Moreover, with respect to specified flood-control
projects in the West, Congress in recent authorizations has ex-
pressly subordinated navigation use of waters to beneficial con-
sumptive use,. exactly as in the case of navigation projects."
Congress has provided that the Secretary shall prescribe reg-
ulations for the use of storage allocated for flood control,
just as in the case of navigation, at all reservoirs con-
structed wholly or in part with federal funds."7 This law does
not apply to the Tennessee Valley Authority, except that in
case of danger rom floods on the lower Ohio and Mississippi

1ere as there, significance attaches t the duties, responsibil-
ities, and jurisdiction of the International Joint Commission.';
Similarly pertinent iere are the-daties, responsibilities, and
jurisdiction of the International Boundary and Water Com-
mission, United States and Mexico.i" The Convention of Feb-
ruary 1, 1933, provides for rectification by the Commiosion
of the Rio Grande between El Paso and Fort Quitman, Texas,
for flood protection and for the stabilization of the intemra
tiorial boundary." Likewise, the Secretary of State-, actg
through the American Commissioner, is authorized to conduct
investigations relating to flood control anong other things,
upon the boundary between the United States and Mexico.12
And the President has authority over construction, operation,
and maintenance of any project provided for in a treaty with
Mexico." Also, Congress has authorized the .United States
Section of the Commission to con;truct the Rio Grande Canali-
zation Project, designed primarily for flood control ando facil-
itate compliance with the Water Conventioin of lfay 21, 1906."
