1. The appellant was organized to build and operate a railway from the north line of the city of Stillwater to the south line of the town of Baytown, in Washington county, the principal object of which was to connect by railway the different railroads now terminating in the city of Stillwater, viz., those whose depot is in the lower or southern, and those whose depot is in the upper or northern, end of the city, appellant’s road being designed as a transfer road between them. The appellant had instituted proceedings to condemn, for the purposes of their road, the property of respondents. Upon the trial of an appeal from the award of the commissioners, the only matter in issue being the value of the property, the court, under the. objection and exception of the railway company, allowed the follow*299ing question to be asked of a witness on the part of the land-owners: “Is there any other route by which connections can be made between the lower depot and the upper depot, except across this land?” — to which the answer was: “Not that I know of. There is a high ledge of rocks extending north of the lower depot, and the upper depot is situated near the lake shore, on a line direct from the lower to the upper depot. The main street is full of business blocks.” We think this was error. This evidence did not fairly tend to show the market value of the property, or even its general fitness for railroad purposes. The manifest purpose of it was to show that the railway company had got to have it, and therefore to make their necessities, rather than the market value of the property, the measure of the landowners’ compensation. The idea that a jury would naturally get from the admission of such evidence would be that the petitioner should be made to pay all they could afford to pay rather than do without the property, without reference to what it was fairly worth. In determining the actual value, everything, of course, which enhances its present worth should be taken into consideration; not, however, the fact that it is necessary or indispensable for the public use for which it is proposed to be taken.
Suppose the public were laying out a highway of great public importance and necessity, through a narrow ravine, would it be competent to show that this was the only practicable or possible route, so as to make the public pay for the land what they might be willing to pay under compulsion rather than do without the highway? Or suppose a railroad was intended to be built through some canyon or mountain pass, the soil of which was of little or no practical value, would it be competent to permit the owner to show that it furnished the only possible route for the road? We apprehend not. These are extreme cases, but not different in principle from the one under consideration. Stinson v. Chicago, St. P. & M. Ry. Co., 27 Minn. 284; Virginia & T. R. Co. v. Elliott, 5 Nev. 358, (296.) The error in admitting this evidence was afterwards emphasized by the court’s refusing to instruct the jury that, in estimating the value of the property, they were not to consider the necessity of the petitioner.
2. On the trial much evidence was introduced as to the value of *300the property in consideration of its supposed fitness for various uses, such as that of a site for warehouses, or coal-yards, and the like, which would naturally depend somewhat on its railroad facilities. The court refused the request of'the petitioner to instruct the jury: “In estimating the market value of this property, the jury cannot include any increase in value to the same that they may think will accrue to it from the construction of the contemplated railroad.” We think the petitioner -was fairly entitled to this instruction. . It is true, the court did instruct the jury generally that they were to estimate the value of the property as of the time it was taken, but we think that, under the circumstances, the petitioner was entitled to a more specific instruction, to the effect that in estimating this value they were not to include any mere prospective or future increase of value, to result from the completion of the proposed improvement. Of course, any increase in value which the property had already experienced by reason of the commencement or public exxiectation of the improvement would properly be considered, because that had already affected its present market value. But the purpose of the request was to prevent the jury from taking into account any supposed future increase of value that might thereafter occur.
3. The property in question was situated upon the shore of the navigable waters of Lake St. Croix; hence, the case presents some important questions as to the extent and nature of the rights of the 'respondents as riparian owners. At common law, the king, as representative of the nation, held in trust for them all navigable waters, and the title to the soil under them. This was a sovereign or prerogative, and not a proprietary right. At the revolution the people of each state became sovereign, and in that.capacity held all these navigable waters and the soil under them for their common use, subject only to the rights since surrendered to the general government. Martin v. Waddell, 16 Pet. 367; Mumford v. Wardell, 6 Wall. 436. New states, since admitted, have the same rights in these navigable waters as the original states. Upon the admission of a new state, this right of eminent domain in them, which was temporarily held by the United States, passes to the state. The patent from the United States of land on a navigable stream conveys to the patentee no title to the *301bed of the stream. This vests in the state as a sovereign right. Pollard v. Hagan, 3 How. 212, 222; Mumford v. Wardell, supra.
In some states it is held (following the analogy of the common-law rule applicable to waters where the tide ebbs and flows) that a riparian owner on a navigable stream has the fee only to ordinary high water. Such seems to be the tenor of the decisions of the federal courts. But, as it is wholly a matter for the state to determine the extent of its own rights, they follow on this question the decisions of the state courts.
In this state it is the settled doctrine that the riparian owner has-the fee to low-water mark. Schurmeier v. St. Paul & Pac. R. Co., 10 Minn. 59, (82;) Brisbine v. St. Paul & Sioux City R. Co., 23 Minn. 114. But while he only has the fee to low-water mark, he has certain riparian rights incident to the ownership of real estate bordering upon a navigable stream. Among these are the right to enjoy free communication between his abutting premises and the navigable channel of the river, to build and maintain suitable landings, piers, and wharves, on and in front of his land, and to extend the same therefrom into the river to the point of navigability, even beyond low-water mark, and, to- this extent, exclusively to occupy for such and like purposes the bed of the stream, subordinate only to the paramount public right of navigation. Dutton v. Strong, 1 Black, 22; Railroad Co. v. Schurmeir, 7 Wall. 272; Yates v. Milwaukee, 10 Wall. 497, supra; Rippe v. Chicago, D. & M. R. Co., 23 Minn. 18; Brisbine v. St. Paul & Sioux City R. Co., supra. These riparian rights are property, and cannot be taken away without paying just compensation therefor. The state could not do it or authorize anyone else to do it. Yates v. Milwaukee, supra; Lyon v. Fishmongers' Co., L. R. 1 App. Cas. 662; Brisbine v. St. Paul & Sioux City R. Co., supra.
The term “point of navigability,” as used in the cases referred to, is not, perhaps, capable of a fixed definition. Its meaning and application must vary with and depend upon circumstances. It is not to be understood in the narrow sense of being limited to that point ■where the waters of the stream may be navigable for some purposes-at certain stages of water. When it said that a riparian owner may construct landings, etc., “to the point of navigability,” it must be *302understood as giving him the right to do so to the extent necessary to make his abutting property reasonably available at any ordinary stage of water, for any kind of navigation for which the stream is used, and for which it is adapted, provided, of course, it does not obstruct the paramount rights of the public. It must have reference not only to an ordinarily low stage of water, but also the size and kind of vessels which navigate the stream, and the kind of business done upon it. The right would be of little value if it did not permit this to be done. Neither is it material whether, in exercising these riparian rights; the property is made available and useful by building piers and landings of wood or other material, or, as is the usual, and often the only practical, way on the Mississippi and its tributaries, by reclaiming the land by artificial filling with earth out to the requisite depth of water. Whether the fee in this “made land” would be in the state or in the riparian owner — that is, whether it partakes of the nature of the bed of the stream upon which it is made, or of the shore to which it is added — may be a question of speculative interest, but it is not one of any practical importance. If the fee be in the riparian owner, yet, of course, it must be a qualified fee; that is, subject to the paramount right of public navigation. But if it be in the state, the riparian owner still has, subject to this same public right, the exclusive right of possession and the entire beneficial interest. Hence, the determination of the question one way or the other would not affect the value of the riparian owner’s interest in the property, or the amount of compensation he is entitled to.
Suppose, however, a riparian owner has unlawfully intruded into the water beyond the point of navigability, as above defined, and filled up the bed of the stream beyond that point, for the sole purpose of extending his possessions, and so as to obstruct and interfere with the public right of navigation. This would constitute a purpresture. The public would have a right to abate it as a public nuisance. It would give no rights to the person who made it. It would not forfeit or destroy his riparian rights as they existed before, but he could claim no additional rights on account of it. When it is proposed to take Ills property for public use by the exercise of eminent domain, he can claim no additional compensation by reason of it. When con*303•demned or taken, tbe corporation which acquired it would presumably have to remove it, — at least, there is no presumption that it would be allowed to remain, — and therefore there is no reason why the party condemning the property should pay more for it on account of his unlawful encroachment upon public rights. The mere chance that it might be allowed to remain, cannot be made the basis of compensation to the person who made it.
In the present ease, while there is evidence tending to prove that a part of these premises is “made land” situate beyond the original low-water mark, made partly by natural alluvions or washings from the neighboring shore, and partly by artificial fillings, yet we find nothing in the case tending to show that land has been reclaimed by artificial means beyond the point of navigability, as we have defined that term; and, in the absence of evidence, the presumption is the other way. Dutton v. Strong, supra; Carli v. Stillwater, etc., Ry. Co., 28 Minn. 373. Hence, by examination of the requests refused, and of the instructions actually given by the court upon questions touching the riparian rights of the respondents, it will be seen that, although they may not in all respects conform to the views we have expressed, .yet, under the evidence, they involved no error prejudicial to the appellant.
It also follows that the act of the legislature (Sp. Laws 1881, (Ex. Sess.) c. 101,) by which they assumed to authorize the appellant, by and with the consent of the city of Stillwater, to use and occupy with its structures that part of Lake St. Croix in front of the city of Still-water between low-water mark and the centre of the lake, cannot affect the rights of the respondents as riparian owners, and hence cuts no figure in this case.
Whether, in view of the fact that the rights of the state to the stream and its bed are sovereign and not proprietary, and are held by it in trust for the public as a highway, and the further fact that congress has, in the act authorizing a state government, expressly provided that the Mississippi river and the waters leading into the same shall be common highways and forever free to the inhabitants of the state, and all other citizens of the United States, the legislature has the power to divert the bed of the St. Croix from the trust for which *304it was vested in the state, and destroy the public use of it as a publiehighway, is a question not here involved and which we do not consider. It is sufficient to say that they cannot by any such grant impair or take away the riparian rights of the respondents without compensation. But, for the errors occurring at the trial, already pointed out, the order appealed from must be reversed, and a new trial ordered.
Ordered accordingly.
