The extent and validity of federal power under the Wilderness Act of 1964 and the Michigan Wilderness Act of 1987 form the central issues of this appeal. Plaintiffs are possessors of surface rights to a lake, held in common with the United States. They challenge certain United States Forest Service restrictions on activities on the lake, claiming that they are beyond the Forest Service’s statutory and constitutional authority. The district court upheld the restrictions, finding them to be within the power granted by the Property Clause of Article IV, Section 3, Clause 2, and finding that plaintiffs’ property rights were subject to reasonable regulation under Michigan law. Because we conclude that the Property Clause gives Congress the power to regulate the lake, that Congress has delegated authority to the Forest Service to regulate the lake, and that regulation of the lake does not exceed the wilderness acts’ express limitations deferring to state law property rights, we affirm.
Plaintiffs own land on the northern shore of Crooked Lake, in Michigan’s Upper Peninsula near the Wisconsin border. Because of their ownership, plaintiffs possess “riparian,” or “littoral,” rights under Michigan law — i.e., common property interests in Crooked Lake’s surface.
At issue are certain management prescriptions of the Forest Service relating to the portion of Crooked Lake lying within the Sylvania Wilderness Area. Amendment No. 1, adopted by the Forest Service in 1992 to amend its national forest land and resource management plan governing the Sylvania Wilderness, prohibits, among other things, the use of “sail-powered watercraft,” “watercraft designed for or used as floating living quarters,” and “[njonburnable disposable food and beverage containers” in the wilderness. (Admin.Rec.36, 38.) Land and resource management plans are prepared under the guidelines of 16 U.S.C. § 1604 and 36 C.F.R. § 219, which provide for notice and opportunity to comment on proposed plans and amendments, and Amendment No. 1 was properly adopted pursuant to this framework. Notably, Amendment No. 1 has no effect on the small bay outside the wilderness area on which plaintiffs’ properties lie. But because plaintiffs have riparian rights in the whole surface of Crooked Lake, they claim that Amendment No. l’s restrictions on sailboats, houseboats, and food containers are an unauthorized infringement of their rights to unrestricted use of the entire lake. According to plaintiffs, both the Wilderness Act of 1964 (“Wilderness Act”), 16 U.S.C. §§ 1131-1136, which established the National Wilderness Preservation System, and the Michigan Wilderness Act of 1987 (“MWA”), Pub.L. No. 100-184, 101 Stat. 1274, which specifically established the Sylvania Wilderness, expressly limit the power of the federal government to regulate in the face of private property rights. The Wilderness Act states:
Except as specifically provided for in this chapter, and subject to existing private rights, there shall be no commercial enterprise and no permanent road within any wilderness area designated by this chapter and, except as necessary to meet minimum requirements for the administration of the area for the purpose of this chapter ... there shall be no temporary road, no use of motor vehicles, motorized equipment or motorboats, no landing of aircraft, no other form of mechanical transport, and no structure or installation within any such area.
16 U.S.C. § 1133(c) (emphasis added). The MWA, incorporating the Wilderness Act by reference, states:
Subject to valid existing rights, each wilderness area designated by this Act shall be administered by the Secretary of Agriculture in accordance with the provisions of the Wilderness Act of 1964 governing areas designated by that Act as wilderness areas....
Pub.L. No. 100-184, § 5, 101 Stat. 1274, 1275-76 (1987) (emphasis added). Because
Plaintiff Kathy Stupak-Thrall initially challenged the promulgation of Amendment No. 1 with the Forest Service, in accordance with the appeal procedures of 36 C.F.R. § 217. The Regional Forester denied Thrall’s first-level appeal, finding that “valid existing rights” in the MWA referred only to mineral rights in a different Michigan wilderness.

We review a district court’s award of summary judgment de novo. City Management Corp. v. U.S. Chemical Co.,
The Forest Service’s authority is grounded in Congress’s authority under the Property Clause, which declares that “The Congress shall have Power to dispose of and make all
Camfield holds that the Property Clause is broad enough to permit federal regulation of fences built on private land adjoining public land when the regulation is for the protection of federal property. Camfield contains no suggestion of any limitation on Congress’ power over conduct on its own property; its sole message is that the power granted by the Property Clause is broad enough to reach beyond territorial limits.
Kleppe itself held that Congress may regulate wild animals on public land under the Property Clause. In the actual controversy before the Court, wild burros had been seized directly on the federal land, but the statute at issue also provided for regulation of “protected horses or burros [which] ‘stray from public lands onto privately owned land.’ ” Id. at 531-32,
The Eighth and Ninth Circuits have applied Camfield, Alford, and Kleppe in analogous circumstances to the instant case. In United States v. Lindsey,
In two Minnesota cases, the Eighth Circuit held that the Property Clause would permit congressional regulation in factual situations very similar to our own. The court in United States v. Brown,
Block and Brown involved federal regulation of state-owned waters (or arguably state-owned waters in the case of Brown). The present action, however, involves shared ownership of the surface waters between the federal government and private citizens. If
There can be little question that Congress has the power to regulate Crooked Lake in the manner described by Amendment No. l’s management prescriptions. The Property Clause gives Congress broad authority to decide what are “needful” regulations “respecting” federal property. Kleppe instructs: “[W]e must remain mindful that, while courts must eventually pass upon them, determinations under the Property Clause are entrusted primarily to the judgment of Congress.”
Ill
Once we determine that Congress has the authority to prohibit sailboats, houseboats, and certain food containers on Crooked Lake, the remaining question is whether the Forest Service may do the same. One factor that sets the instant action apart from all of the foregoing cases is the provision by Congress in each of the wilderness acts making any regulation “subject to” already “existing” property rights. This specific statutory limitation on the Forest Service’s actions requires that we examine exactly what those “existing” rights are, and we do so in part IV below. First, however, we address plaintiffs’ contention that Congress has not authorized the Forest Service to regulate under the Property Clause at all. Essentially, plaintiffs argue that the Forest Service cannot point to any statute that might give it the power to make “needful Rules and Regulations respecting” government property. According to plaintiffs, only “Congress” is named in the Property Clause and therefore only Congress may regulate, absent a specific legislative delegation.
Plaintiffs claim that the Forest Service cannot regulate Crooked Lake pursuant to the Organic Act because the Wilderness Act provides that federal land may only be “designated as ‘wilderness areas’ ” under the Wilderness Act itself or “a subsequent act,” and the Organic Act is not a subsequent act. 16 U.S.C. § 1131(a). This argument confuses “designation” or establishment of wilderness areas with simple management or regulation. The Sylvania Wilderness Area was designated by “a subsequent act” — the MWA — in
Plaintiffs also make two other claims based on fundamental misreadings of text. First, they assert that Amendment No. 1 is inconsistent with a portion of the Weeks Act which states that the establishment of national forests will not deprive inhabitants of the forest area of “their rights and privileges as citizens.” 16 U.S.C. § 480. What plaintiffs seem to ignore is that this language, taken completely out of context, has no substantive bearing on their property rights under state law. Section 480 merely provides that both the state and the United States shall have general concurrent jurisdiction over individual citizens in forest areas. The “rights and privileges” and “duties” mentioned in the statute are those that attach to individuals “as citizens ” of the state — those that pertain to the state’s exercise of jurisdiction over its citizens. No authority exists for the proposition that this jurisdictional provision somehow shields plaintiffs from regulation by either sovereign.
Second, plaintiffs contend that the Forest Service itself admitted in its 1979 Final Environmental Statement, before the designation of the Sylvania Wilderness Area, that it had no authority to restrict activity on partially federal/partially private property. See Department of Agriculture, Forest Service, Final Environmental Statement: Roadless Area Review and Evaluation (RARE II), FS-325 at 73 (Jan. 1979). Plaintiffs are simply incorrect in their interpretation of RARE II. When the Forest Service states that “non-federal lands included within” wilderness areas “are not themselves classified” as wilderness, such a statement concerns classification only and has nothing to do with the Forest Service’s regulatory authority. It is not an “acknowledgment” that the Forest Service cannot impose restrictions on wilderness that might affect land not “classified” as wilderness.
In short, we hold that Congress has authorized the Forest Service to regulate the Syl-vania Wilderness, and that when the Forest Service acts to preserve “wilderness character” under the Wilderness Act, the scope of authority — except to the extent that Congress may expressly limit it — is coextensive with Congress’s own authority under the Property Clause.
IV
What distinguishes this case from others applying the Property Clause is that the statutory scheme for the federal wilderness areas appears to make explicit room for state law.
As indicated earlier, riparian rights are not absolute. Michigan law divides riparian uses into uses for “natural purposes,” which are “those absolutely necessary for the existence of the riparian proprietor,” and uses related to “artificial purposes,” which are “those which merely increase one’s comfort and prosperity.” Thompson v. Em,
We do not agree that the “reasonable use” doctrine governs the federal government’s actions in this ease. Although the Thompson decision is important here because it shows that the riparian rights of private citizens are not absolute under Michigan law, the “reasonable use” doctrine itself only makes sense when one riparian owner challenges another’s use as unreasonable and the court makes a subsequent determination of reasonableness. It is inapplicable when one riparian proprietor unilaterally decides to ban certain uses of others, whether or not the uses themselves are unreasonable, and whether or not the banning proprietor actually has the power to do so. Indeed, the federal government’s ability to impose restrictions does not stem from its status as a fellow riparian proprietor; it stems from its status as a sovereign. Its authority to regulate cannot come from a state law doctrine that merely balances the property rights of private owners vis-a-vis one another. See Duncan Energy Company v. United States Forest Service,
Instead, we find that Amendment No. l’s management prescriptions are permissible because they constitute a legitimate exercise of the sovereign’s police power. The Michigan Supreme Court has explicitly held that local governments may regulate their citizens’ riparian rights pursuant to their inherent police powers. In Miller v. Fabius Township Board,
Thus, the Forest Service possesses a power delegated to it by Congress that is “analogous to the police power,” and its exercise of this federal power does not violate Congress’s express limitation deferring to “existing” state law rights in the wilderness acts, so long as it does not exceed the bounds of permissible police power regulation under state law. The management prescriptions of Amendment No. 1 are clearly valid restrictions within the state law police power. According to Square Lake Hills, validity depends upon reasonableness, which in turn “depends upon the particular facts of each case.”
If sailboats and houseboats have indeed never been used on Crooked Lake, one could justifiably ask why this action was even brought in the first place. The answer, it appears, is that plaintiffs are going after a bigger fish — Amendment No. 5, which regulates motorboat use on wilderness lakes. The Forest Service had not issued Amendment No. 5 when this case was originally filed, and the amendment does not go into effect until April 1996. Nevertheless, at various points in their brief, plaintiffs intertwine the Amendment No. 5 issue with their discussion of Amendment No. 1, and they use a significant amount of space to attack the merits of the motorboat restrictions. We decline plaintiffs’ invitation to decide the motorboat issue, as it has not been properly presented in this court. Plaintiffs cannot short-circuit the administrative process by challenging Forest Service regulations here, before they have been decided upon in the appropriate agency proceedings. See Lavapies v. Bowen,
V
As a final matter, we note that plaintiffs moved for a stay pending appeal in this court on September 11, 1995.
For the foregoing reasons, plaintiffs’ motion for a stay pending appeal is DENIED, and the district court’s summary judgment in favor of the United States is AFFIRMED.
Notes
. We are told that "littoral” properly refers to property along a lake, whereas "riparian” refers to property along a river. Nevertheless, the word "riparian” may often be “used to describe both types of land and will be so used in this opinion.” Thies v. Howland,
. We follow plaintiffs’ self-designation and refer to Kathy Stupak-Thrall as "Thrall.”
. The United States, while reluctant to accept the district court's interpretation of "valid existing rights” in the MWA, has not appealed this determination. The government concedes also that plaintiffs’ riparian rights are probably protected anyway under the Wilderness Act’s provision regarding "existing private rights,” which is incorporated by reference into the MWA. We therefore proceed under the assumption that riparian rights may be protected under either of the phrases "valid existing rights” or "existing private rights.” Because we ultimately affirm on the ground that Amendment No. l’s restrictions would be a permissible exercise of the police power regardless of whether one or both phrases make an express reservation for riparian rights, we do not and need not decide the definitive interpretation of these terms. See infra part IV.
. As the United States points out, "mechanical transport” in 16 U.S.C. i 1133(c) is defined by the Forest Service as "any contrivance which travels over ground, snow, or water on wheels, tracks, skids, or by floatation and is propelled by a nonliving power source contained or carried on or within the device.” 36 C.F.R. 293.6(a). By adopting Amendment No. 1, the Forest Service has apparently further interpreted "nonliving power source contained or carried on or within the device” to include the wind that propels sailboats.
. No authority exists to support plaintiffs’ implication that whereas the Property Clause might grant Congress broad regulatory powers, Congress's grant to the Forest Service is necessarily less extensive and can only reach property that is exclusively federal. Just the opposite is true. In United States v. Lindsey,
. In addition, plaintiffs fail to demonstrate why mixed federal/private property such as Crooked Lake should necessarily count as "non-federal,” as opposed to "non-private.”
. Again, as explained in note 4, supra, the precise contours of the phrases "valid existing rights” and "existing private rights” need not be decided here.
. Plaintiffs properly moved first for a stay in the district court, which was denied on August 21, 1995.
