A flurry of legal judgments, company statements, and legal presses have actually assembled on the concern of where anglers and hunters can enter Huge Sky Nation– and the response depends upon who you ask.
Montana’s long-simmering battle over public land and water gain access to boiled over in February, driven by parallel advancements that highlight how objected to the state’s outside landscape has actually ended up being. In quick succession, 2 Montana lawmakers revealed a restored push to legislate corner crossing, the Montana Supreme Court bied far a water rights choice on a chronically dewatered trout stream, and Wyoming advanced a costs to codify corner crossing into state law.
For fly fishers preparing a season on Montana’s blue ribbon waters, the message appears: the legal ground below your wading boots is moving.
FWP Holds the Line on Corner Crossing
The driver for much of the present friction is Montana Fish, Wildlife & Parks’ repeated declaration that corner crossing– stepping from one parcel of public land to another at a checkerboard corner without touching personal soil– stays illegal in the state. FWP Director Christy Clark reaffirmed the position in November 2025, weeks after the U.S. Supreme Court declined to hear an appeal from Wyoming’s Iron Bar Holdings v. Cape case. That rejection left undamaged a 10th Circuit judgment that corner crossing is legal– however just in the 6 states within that circuit: Wyoming, Colorado, Utah, Oklahoma, Kansas, and New Mexico. Montana, which beings in the 9th Circuit, was untouched.
FWP’s position has actually drawn continual pushback from Backcountry Hunters & Anglers. Jake Schwaller, now chair of BHA’s Montana chapter, told Montana Free Press in October 2025 that while the 10th Circuit judgment brings “convincing authority” in Montana, the state still requires to solve the concern by itself terms. In a 2024 visitor column in the Bozeman Daily Chronicle, Schwaller– then BHA’s Eastern Montana preservation leader– composed that FWP’s statement was “both factually inaccurate and incorrect,” keeping in mind that no Montana statute or case law makes corner crossing either legal or prohibited. The practice exists in a gray location, he argued, one the executive branch has no authority to solve by fiat.
On the other side, the United Residential Or Commercial Property Owners of Montana has consistently argued that any crossing of a checkerboard corner makes up trespass, no matter whether a boot touches personal ground. UPOM’s position rests on airspace teaching and the property that broadening gain access to total up to a taking of personal property rights.
The stakes are concrete. According to OnX mapping data, approximately 871,000 acres of Montana public land are corner-locked– parcels of federal or state ground that can just be reached at the point where 2 checkerboard corners of public land fulfill. That figure is a subset of some 3 million acres of Montana public land obstructed by surrounding personal holdings.
Lawmakers Promote Clearness
In mid-February 2026, 2 Montana legislators stepped straight into the breach. Sen. Ellie Boldman, D-Missoula, and Rep. Josh Seckinger, D-Bozeman– co-chairs of the Montana Legal Sportsmen’s Caucus–announced their intent to push corner-crossing legislation, composing that they have actually reestablished a costs to clarify that moving from public land to public land at a shared corner, without touching personal property or triggering damage, is not criminal trespass. Montana’s legislature satisfies in routine session just in odd-numbered years, so the effort is targeted at the 2027 session or a possible interim committee action.
Seckinger, a Bozeman fly fishing guide, framed the problem in terms his customers comprehend. Gain access to identifies chance, he composed, and chance drives both involvement and preservation financing. When gain access to diminishes, whatever downstream diminishes with it.
Boldman brought the very first significant effort to legislate corner crossing in 2013 with HB 235. That expense drew busloads of blaze-orange-clad sportspersons to the Capitol however failed, getting simply 45 votes in the 100-member Home– 15 shy of the 60 required to advance. The gain access to issue, she and Seckinger composed, did not disappear.
On The Other Hand, Wyoming is even more along. The Wyoming Home passed HB 19 in February to codify the 10th Circuit’s judgment into state statute. A Senate committee forwarded the bill to the complete chamber on February 26, though ranching groups pressed back on its scope. Oregon is pursuing similar legislation of its own.
Water Rights Judgment Intensifies
On February 24, the Montana Supreme Court provided its choice in Petrich Household Limited Collaboration v. Trout Unlimited (2026 MT 34), a case rooted in the decades-old adjudication of water rights on Mill Creek in Park County.
Mill Creek is an essential tributary of the Yellowstone River and a source of generating environment for Yellowstone aggressive trout ( Oncorhynchus clarkii bouvieri). It is likewise, according to FWP, chronically dewatered– a stream where watering declares currently go beyond physically offered supply. The case fixated whether landowners might broaden the duration of usage for water rights initially decreed as “flood water” claims, restricted to the Might 1 through July 15 window when high circulations make excess water offered.
Trout Unlimited had actually challenged the claims throughout Montana’s basic water adjudication, arguing that creating brand-new “suggested” water rights to extend usage beyond the decreed duration would increase the concern on a currently over-appropriated stream. The Clark Fork Union submitted an amicus quick supporting TU’s position, cautioning that the Water Court’s technique to suggested claims might set a precedent enabling irrigators throughout the state to broaden their diversions at the cost of instream circulations.
The case is technically a water adjudication conflict, however its ramifications ripple outside. For anglers who fish Mill Creek or the Yellowstone River mainstem listed below it, the concern of just how much water remains in the channel throughout late summertime straight identifies whether aggressive trout can generate, rear, and relocation in between tributaries and the river.
What It Suggests for Anglers
These advancements sit at the crossway of 2 pillars that specify Montana fly fishing: stream gain access to and water. Montana’s Stream Access Law of 1985 stays amongst the greatest in the country, ensuring leisure usage of all surface area water listed below the common high-water mark. Corner crossing is, in lots of methods, stream gain access to’s landlocked cousin– the concern of whether the general public can physically reach the water it currently can utilize.
The useful outcome for anybody preparing a 2026 season: corner crossing in Montana stays lawfully dirty. FWP wardens will continue referring believed cases to county lawyers, though no corner-crossing prosecution has actually gone to trial in current memory– charges originating from a 2021 incident involving a Townsend bowhunter were dropped in 2023 simply as the case was headed to a jury. Anglers and hunters who pick to cross at checkerboard corners do so at their own danger, and the danger differs county by county.
On the water side, Mill Creek and streams like it throughout the Yellowstone basin face continued pressure from farming withdrawals, and the Petrich judgment might form how strongly those claims broaden. Trout Unlimited’s water program, which has actually pursued settlements on Mill Creek water rights considering that 2019, will likely weigh the choice’s ramifications before identifying next actions.
Something is clear: the stress in between public gain access to and personal property rights in Montana is not fixing itself. Whether the response originates from the legislature, the courts, or some mix of the 2, the result will identify what Montana’s public waters appear like for a generation.
