interests furnish within that time satisfactory assurances that
such cooperation will be furnished.1"
PLANNING FOR CONSTRUCTION PROGRAM.-In recent Flood
Control Acts, Congress has regularly authorized use of any avail-
able flood-control funds for "plans, specifications, and pre-
liminary work" to enable "rapid inauguration of a construction
SERVICES OF OTHER AGENCIES.-The Secretary is authorized
to cooperate with institutions, organizations, and individuals,
and to utilize the services of federal, state, and other public
agencies in carrying out the purposes of the 1936 Flood Con-
trol Act, as amended and supplemented.10 To this end, he
may pay by check to the cooperating agency, either in advance
or upon the furnishing or performance of the services, all or
part of their estimated or actual cost.1"
WEATHEa BUREm .-In 1938, provision was made for the
establishment, operation, and maintenance by the Weather
Bureau of a current information service on precipitation, flood
forecasts, and warnings, whenever in the opinion of the Chief
of Engineers and the Chief of the Weather Bureau such service
is advisable in connection with either preliminary examina-
tions and surveys or works of improvement authorized by law
for flood-control purposes.1 An expenditure of not to exceed
$375,000 per annum, from flood-control appropriations, is au-
thorized, and the Chief of Engineers may allot to the Weather
Bureau funds for such expenditure."w
Prosecution of Projects
In connection with laws relating to authorization of proj-
ects, we summarized those concerning evacuation, insufficient

authorization, water supply, school facilities, and railroad

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." 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-
ber22, 1944, which relate to the use of dams and reservoirs for
navigation, power, water supply, irrigation, and recreation.11
Similarly, reference was there made to the provisions of
1946 legislation concerning wildlife resources.' So also as to
the provisions of the Act of July 29, 1946, regarding the possible
use of dams as foundations for bridges.5 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.11
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."' This law does
not apply to the Tennessee Valley Authority, except that in
case of danger from floods on the lower Ohio and Mississippi
