Mahlon Pitney United States v. Cress — Opinion of the Court

In Kentucky, and in other states that have rejected the common-law test of tidal flow and adopted the test of navigability in fact, while recognizing private ownership of the beds of navigable streams, numerous cases have arisen where it has been necessary to draw the line between public and private right in waters alleged to be navigable; and by an unbroken current of authorities it has become well established that the test of navigability in fact is to be applied to the stream in its natural condition, not as artificially raised by dams or similar structures

Mahlon Pitney United States v. Cress — Opinion of the Court

The findings make it clear that the dams in question, constructed by the government in the Cumberland and Kentucky rivers, respectively, are for raising the level of those streams along certain stretches by means of backwater, so as to render them, to the extent of the raising, artificial canals instead of natural waterways. In the language of engineering, the government has 'canalized' the rivers. We intimate no doubt of the power of the United States to carry out this kind of improvement.
