The Takings Clause-'nor shall private property be taken for public use, without just compensation,' U.S. Const., Amdt. 5-applies as fully to the taking of a landowner's riparian rights as it does to the taking of an estate in land. See Yates v. Milwaukee, 10 Wall. 497, 504, 19 L.Ed. 984 (1871). Moreover, though the classic taking is a transfer of property to the State or to another private party by eminent domain, the Takings Clause applies to other state actions that achieve the same thing. Thus, when the government uses its own property in such a way that it destroys private property, it has taken that property. See United States v. Causby, 328 U.S. 256, 261-262, 66 S.Ct. 1062, 90 L.Ed. 1206 (1946); Pumpelly v. Green Bay Co., 13 Wall. 166, 177-178, 20 L.Ed. 557 (1872).
