waters. If navigable in fact the stream is navigable in law. Navigability has been defined: “ The true rule is, that the public have a right of way in every stream which is capable, in its natural state .and its ordinary volume of water, of transporting, in a condition fit for market, the products of the forests or mines, or of the tillage of the soil upon its banks. It is not essential to the right that the property to be transported should be carried in vessels, or in some other mode, whereby it can be guided by the agency of man, provided it can ordinarily bo carried safely without such guidance. Nor is it necessary that the stream should be capable of being thus navigated against its current, as well as in the direction of its current. If it is so far navigable or floatable, in its natural state and its ordinary capacity, as to be of public use in the transportation of property, the public claim to such use ought to be liberally supported. Nor is it essential to the easement that the capacity of the stream, as above defined, should be continuous, or, in other words, that its ordinary state,
at all seasons of the year, should be such as to make it navigable. If it is ordinarily subject to periodical fluctuations in the volume and height of its water, attributable to natural causes, and recurring as regularly as the seasons, and if its periods of high water or navigable capacity ordinarily continue a sufficient length of time to make it useful as a highway, it is subject to the public easement.”
(Morgan v. King, 35 N. Y. 454 , 459.) And again: “ The capability of use by the public for purposes of transportation and commerce affords the true criterion of the navigability of a river, rather than the extent and manner of that use. If it be capable in its natural state of being used for purposes of commerce, no matter in what mode the commerce may be conducted, it is navigable in fact, and becomes in law a public river or highway.”
(Economy Light Co. v.
United States, 256 U. S. 113 , 122.) The fact that the bed of the stream to its center is privately owned, or owned by the carrier assessed, does not affect its navigability or its character as a public highway; navigability rests upon the water, not on the underlying lands. The title to the lands within rural highways is generally privately held and a railroad company cannot avoid a special franchise tax at its crossing by purchasing title to the lands under its crossing. Also the fact that there are dams in the Genesee river, over which boats of any size, and logs even, cannot pass, is not germane to the question of navigability. These dams only occasion a present condition; and, if this is a public stream and the dam is an obstruction to navigation and commerce, the State, under its power to improve the stream for purposes of navigation and commerce, can require its removal or modification in such manner as to permit navigation without incurring on the part of the State liability to the riparian owner, or the owner of the dam.
(Fulton L., H. & P. Co. v.
State, 200 N. Y. 400 .) In determining navigability we consider the stream in its natural state and not as changed by artificial conditions. We pass then to the real issue: What is the actual condition of this stream as to its capacity for navigation? The referee says in his opinion: “ Assuming the stream to have been navigable at one time and not navigable at the times
in question, does the change to a stream not navigable in fact extinguish the public right or interest? There can be little question from the record in this case, that the Genesee river at one time was 1 navigable ’ within the construction put by the courts upon the term.” And the referee finds that, though navigable at one time, it is not at present a navigable stream. This conclusion is due, not to the fact that the capacity of the stream has lessened since the earlier .days, but to
