Search 33 U.S.C. § 594 : US Code - Section 594: When immediate possession of land may be taken

Whenever the Secretary of the Army, in pursuance of authority
conferred on him by law, causes proceedings to be instituted in the
name of the United States for the acquirement by condemnation of
any lands, easements, or rights of way needed for a work of river
and harbor improvements duly authorized by Congress, the United
States, upon the filing of the petition in any such proceedings,
shall have the right to take immediate possession of said lands,
easements, or rights-of-way, to the extent of the interest to be
acquired, and proceed with such public works thereon as have been
authorized by Congress: Provided, That certain and adequate
provision shall have been made for the payment of just compensation
to the party or parties entitled thereto, either by previous
appropriation by the United States or by the deposit of moneys or
other form of security in such amount and form as shall be approved
by the court in which such proceedings shall be instituted. The
respondent or respondents may move at any time in the court to
increase or change the amounts or securities, and the court shall
make such order as shall be just in the premises and as shall
adequately protect the respondents. In every case the proceedings
in condemnation shall be diligently prosecuted on the part of the
United States in order that such compensation may be promptly
ascertained and paid.
