delivered the opinion of the Court.
In this case the Court is asked to decide whether the compensation which the United States is constitutionally required to pay when it condemns riparian land includes the land’s value as a port site. Respondents owned land
The Commerce Clause confers a unique position upon the Government in connection with navigable waters. “The power to regulate commerce comprehends the control for that purpose, and to the extent necessary, of all
The navigational servitude of the United States does not extend beyond the high-water mark. Consequently, when fast lands are taken by the Government, just compensation must be paid. But “just as the navigational privilege permits the Government to reduce the value of riparian lands by denying the riparian owner access to the stream without compensation for his loss, ... it also permits the Government to disregard the value arising from this same fact of riparian location in compensating

v.
Twin City Power Co.,
We are asked to distinguish between the value of land as a power site and its value as a port site. In the power cases, the stream is used as a source of power to generate electricity. In this case, for the property to have value as a port, vessels must be able to arrive and depart by water, meanwhile using the waterside facilities of the port. In both cases, special value arises from access to,

v.
United States,
Finally, respondents urge that the Government’s position subverts the policy of the Submerged Lands Act, 3 which confirmed and vested in the States title to the lands beneath navigable waters within their boundaries and to natural resources within such lands and waters, together with the right and power to manage, develop, and use such lands and natural resources. However, reliance on that Act is misplaced, for it expressly recognized that the United States retained “all its navigational servitude and rights in and powers of regulation and control of said lands and navigable waters for the constitutional purposes of commerce, navigation, national defense, and international affairs, all of which shall be paramount to, but shall not be deemed to include, proprietary rights of ownership . 4 Nothing in the Act was to be construed “as the release or relinquishment of any rights of the United States arising under the constitutional authority of Congress to regulate or improve navigation, or to provide for flood control, or the production of power.” 5 The Act left congressional power over commerce and the dominant navigational servitude of the United States precisely where it found them.
For the foregoing reasons, the judgment of the Court of Appeals is reversed and the case remanded with direction to reinstate the judgment, of the District Court.
Reversed and remanded.
