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 ”
