Stripped of frivolous issues, this is a dispute between neighbors over the level of Duck lake in Oakland county. The parties to .the instant suit own adjoining lands. Plaintiffs’ property lies to the south of defendants’ property.

If the normal level of Duck lake is 1,014.63 feet 1 above sea level, or less, as claimed by the plaintiffs, the northernmost lake waters would not touch the defendants’ land in the area known as the bay, and. consequently the defendants would have no littoral *701 rights 2 in this area. However, if the normal height of the lake is 1,016.63 feet as contended by the defendants, the waters of Duck lake would touch defendants’ land in the bay area, rendering those lands littoral in character. 3

A rough diagram of the land holdings of the parties may contribute to the reader’s understanding of this case.

The trial judge found that a fence which the plaintiffs were in the process of erecting on their own land would have interfered with the defendants’ riparian rights. As shown in the diagram, this fence was to run in an easterly direction through the bay area. The trial court concluded that defendant John Naimish was justified in pulling'up the posts of this fence. Plaintiffs challenge this ruling on appeal.

In addition to plaintiffs’ allegations that the defendants destroyed the fence under construction, the plaintiffs made the following allegations against the defendants: '■ ■'

That the defendants destroyed portions of an old boundary line fence, which had become, through mutual acquiescence, the lawfuPboundary;

That the defendants moved and relocated fence posts of the old''boundary line fence to the south of their proper position;

That the defendants cut down- a large willow tree, 3 feet "in diameter, which stood' partly on the plaintiffs’ land;

That the defendants removed other trees and other vegetation from the plaintiffs’ property ;

*702

*703 That the defendants dng ont and lowered land near the mutual boundary line in the bay area in order to cause the lake to reach the defendants’ property.

The trial judge found against the plaintiffs on each of these allegations, and his findings are well supported by the evidence. We affirm such findings without further discussion.

We return now to the issue concerning the fence, the lake level and the littoral rights of the defendants. Among the rights of a littoral owner is the right to use his upland property to gain access to the lake waters; the right to put out in a boat or on foot from his upland property where it touches the lake waters; the right, after so embarking, to go boating, swimming, water skiing, fishing, ice skating or sledding or to engage in other aquatic; sports, in or upon the lake waters; and the right to use the entire surface and subsurface lake waters for such purposes. Burt v. Munger (1946), 314 Mich 659; Manney v. Prouse (1929), 248 Mich 655; Kerley v. Wolfe (1957), 349 Mich 350. Each littoral owner shares such rights with all other littoral owners and none may interfere, unreasonably, with like rights, of the others. Beach v. Hayner (1919), 207 Mich 93.

In a small inland lake, like this one, which is not navigable in any important commercial sense, the owner of uplands holds title to the submerged extension thereof to the center of the lake bed, apportioned, with other littoral owners, where indicated by the configuration of the lake and abutting land parcels. Ottawa Shores Home Owners Association, Inc., v. Lechlak (1955), 344 Mich 366; Bauman v. Barendregt (1930), 251 Mich 67; Moore v. Provost (1919), 205 Mich 687. 4

*704 On the facts in this case, it is clear that the plaintiffs’ fence was being constructed upon lands owned by them whether or not such lands were submerged. Ottawa Shores Home Owners Association, Inc., v. Lechlak, supra.

Nevertheless, if the defendants’ lands in the bay area were littoral, and the plaintiffs’ projected fence interfered with the defendants’ exercise of any of the previously described littoral rights, the defendants would be privileged to prevent construction of the fence or to demolish it during construction or thereafter, and the defendants would not need permission of a court to do so. Manney v. Prouse, supra.

With the lake level at 1,016.63 feet the defendants would be able to enter the lake from their own uplands in the bay area, but the way to deeper waters would be barred by the Rices’ new fence. Such a barrier, even though it was on the Rices’ own property, would violate the Naimishes’ littoral rights. Kerley v. Wolfe, supra.

On four separate occasions in the recent past, of which this is the latest, courts of competent jurisdiction have held that the usual, normal, and lawful level of Duck lake is 1,016.63 feet. These determinations were all made in cases in which one or both of the plaintiffs were parties.

The first such determination was made by the Oakland circuit court in a case (No. 027821) brought by the Naimishes against Norman Rice and his vendor , under land contract. The circuit court held, inter alia, that, with the lake at 1,016.63 feet, the Naimishes had riparian rights in the bay area. The trial court’s decision was affirmed by the Supreme Court, Naimish v. Wardlow (1961), 362 Mich 198, and Norman Rice’s motion for rehearing was denied by the Supreme Court on February 28, 1961.

*705 Three months later, Muriel Rice brought a mandamus action in Oakland circuit court (No. L52373) to compel the Oakland county drain commissioner to lower the level of Duck lake to 1,013.56 feet. Norman Rice was added as a party and he adopted the position of his plaintiff wife. In July of 1962, the circuit court denied the Rices’ mandamus petition on the ground that it was bound by the lake level determination which earlier had been made by the circuit court and affirmed by the Supreme Court. No appeal was taken.

In still another suit (No. L54394) the Oakland county board of supervisors sought a judicial determination of the lawful level of Duck lake. The Rices and John Naimish appeared and participated in this lawsuit. Ultimately, after contested hearings, this case was disposed of by an order on June 18, 1962, which established the normal and lawful elevation of Duck lake at 1,016.63 feet. No appeal was taken.

Under these circumstances, the trial judge was correct in placing upon the plaintiffs the burden of proving any lake level less than 1,016.63 feet.. ;

Further, the trial judge was correct in the legal conclusion, implicit in his decision, that the existence or nonexistence of littoral rights is to be determined with the lake waters in their usual and normal condition. A temporary departure from this condition does not alter the littoral character of lands or. the littoral rights of owners of such lands. Troska v. Brecht (1918), 140 Minn 233 (167 NW 1042); Tucker v. Mortenson (1914), 126 Minn 214 (148 NW 60). Also, see Kerley v. Wolfe, supra; Burt v. Munger (1946), 314 Mich 659; and Ruggles v. Dandison (1938), 284 Mich 338, suggesting that it is' the natural and normal, rather than any temporary, condi *706 tion of a lake, which determines the littoral char, acter of land.

We are reviewing a chancery ease. We do so de novo on the record, giving considerable weight to the findings of the trial court. Christine Building Company v. City of Troy (1962), 367 Mich 508. The record is replete with evidence showing that the level of Duck lake is subject to temporary fluctuations depending upon the degree of precipitation. The evidence clearly demonstrates that the usual, natural, ordinary, and normal level of the lake is 1.016.63 feet. The record is uncontradicted that the lake temporarily falls below this level in periods of unusual drought, but returns to the height of 1,016.63 feet in periods of normal precipitation. Similarly the evidence shows that the lake is higher than 1.016.63 feet in periods of abnormally heavy precipitation, but returns to this level in periods when precipitation is normal. The record is virtually devoid of evidence of any permanent dropping of the lake level below 1,016.63 feet.

There is an issue of fact as to whether the waters of Duck lake touched the defendants’ land in the bay area at the time when plaintiffs’ fence was being built. Evidently the trial judge believed that they did. Whether he was correct in his belief is immaterial, because the fence would interfere with the Naimishes’ littoral rights with the lake in its usual, ordinary, and natural condition.

In summary, with the lake level at 1,016.63 feet, the waters of Duck lake touch the defendants’ land in the bay area. After the plaintiffs lost a series of lawsuits which established the level of Duck lake at 1,016.63 feet, it was incumbent upon them to prove that the high and dry nature of the Naimishes’ bay area lands was more than a temporary, fleeting condition. This they clearly failed to do. Much *707 to the contrary, the evidence demonstrates that if the lake level was below 1,016.63 feet at the time of the Bices’ fence project, its restoration to that level was, in all probability, imminent and inevitable. Thus, the fence under construction offended the Naimishes’ littoral rights and the trial judge properly found that John Naimish was privileged to destroy it.

This is the fourth full dress lawsuit in recent years over the level of Duck lake. There have been at least as many summary proceedings ancillary to the plenary lawsuits. The Bices have lost all of the legal battles to date. This should be the last in the series.

In one of the many legal skirmishes, Norman Bice was adjudged in contempt of a permanent injunction which restrained him from filling in lake waters near the Naimishes’ lands. Even this did not stop the Bices from waging their legal wars over the lake level. Seemingly, the Bices cannot accept defeat. One of the reasons is not hard to find. With the lake at 1,016.63 feet the bay extends north over the Bices’ property onto the Naimish tract, dividing the Bices’ property into two parcels. The Bices have tried to unite the divided parcels by building a road or causeway through the bay area. In periods of drought, they have tried to raise their lands in the bay area so high that Duck lake waters would never again lap over upon the Naimishes’ property. Uniting the parcels separated by the bay seems to have become an obsession with the Bices. The Naimishes, on the other hand, are equally determined not to lose their bay area littoral rights. They have had to defend these rights time and again. Each time the Naimishes have prevailed. Four times is more than enough.

Should the Bices attempt for a fifth time to litigate the lake level, we commend to the tria,! court’s *708 consideration a requirement that the Rices post security for costs, including the actual costs of preparation and trial, together with actual attorney’s fees not to exceed a reasonable amount, G-CR •1963, 109.

We have considered imposing costs for vexatious appeal, but have, not done so, because there is a dearth of clear-cut Michigan authority regarding the effect of a temporary recession of lake waters upon the rights of littoral owners.

Affirmed, with costs to the appellees.
