Montana’s Access Wars Heat Up as Corner Crossing, Water Rights Collide

A flurry of authorized rulings, company declarations, and legislative pushes have converged on the query of the place anglers and hunters can go in Huge Sky Nation—and the reply will depend on who you ask.

Montana’s long-simmering struggle over public land and water entry boiled over in February, pushed by parallel developments that underscore how contested the state’s outside panorama has change into. In speedy succession, two Montana legislators introduced a renewed push to legalize nook crossing, the Montana Supreme Courtroom handed down a water rights choice on a chronically dewatered trout stream, and Wyoming superior a invoice to codify nook crossing into state legislation.

For fly fishers planning a season on Montana’s blue ribbon waters, the message is obvious: the authorized floor beneath your wading boots is shifting.

FWP Holds the Line on Nook Crossing

The catalyst for a lot of the present friction is Montana Fish, Wildlife & Parks’ repeated declaration that nook crossing—stepping from one parcel of public land to a different at a checkerboard nook with out touching personal soil—stays illegal within the state. FWP Director Christy Clark reaffirmed the position in November 2025, weeks after the U.S. Supreme Courtroom declined to hear an enchantment from Wyoming’s Iron Bar Holdings v. Cape case. That refusal left intact a tenth Circuit ruling that nook crossing is authorized—however solely within the six states inside that circuit: Wyoming, Colorado, Utah, Oklahoma, Kansas, and New Mexico. Montana, which sits within the ninth Circuit, was unaffected.

FWP’s stance has drawn sustained pushback from Backcountry Hunters & Anglers. Jake Schwaller, now chair of BHA’s Montana chapter, told Montana Free Press in October 2025 that whereas the tenth Circuit ruling carries “persuasive authority” in Montana, the state nonetheless must resolve the query by itself phrases. In a 2024 visitor column within the Bozeman Daily Chronicle, Schwaller — then BHA’s Japanese Montana conservation chief—wrote that FWP’s declaration was “each factually incorrect and false,” noting that no Montana statute or case legislation makes nook crossing both authorized or unlawful. The apply exists in a grey space, he argued, one the chief department has no authority to resolve by fiat.

On the opposite facet, the United Property Homeowners of Montana has consistently argued that any crossing of a checkerboard nook constitutes trespass, no matter whether or not a boot touches personal floor. UPOM’s place rests on airspace doctrine and the premise that increasing entry quantities to a taking of personal property rights.

The stakes are concrete. In keeping with OnX mapping data, roughly 871,000 acres of Montana public land are corner-locked — parcels of federal or state floor that may solely be reached on the level the place two checkerboard corners of public land meet. That determine is a subset of some three million acres of Montana public land blocked by surrounding personal holdings.

Legislators Push for Readability

In mid-February 2026, two Montana lawmakers stepped immediately into the breach. Sen. Ellie Boldman, D-Missoula, and Rep. Josh Seckinger, D-Bozeman—co-chairs of the Montana Legislative Sportsmen’s Caucus—announced their intent to push corner-crossing legislation, writing that they’ve reintroduced a invoice to make clear that transferring from public land to public land at a shared nook, with out touching personal property or inflicting harm, is just not prison trespass. Montana’s legislature meets in common session solely in odd-numbered years, so the trouble is aimed on the 2027 session or a possible interim committee motion.

Seckinger, a Bozeman fly fishing information, framed the problem in phrases his shoppers perceive. Entry determines alternative, he wrote, and alternative drives each participation and conservation funding. When entry shrinks, every part downstream shrinks with it.

Boldman carried the primary main try and legalize nook crossing in 2013 with HB 235. That invoice drew busloads of blaze-orange-clad sportsmen to the Capitol however fell brief, receiving simply 45 votes within the 100-member Home—15 shy of the 60 wanted to advance. The entry drawback, she and Seckinger wrote, didn’t go away.

In the meantime, Wyoming is additional alongside. The Wyoming Home handed HB 19 in February to codify the tenth Circuit’s ruling into state statute. A Senate committee forwarded the bill to the complete chamber on February 26, although ranching teams pushed again on its scope. Oregon is pursuing similar legislation of its personal.

Water Rights Ruling Provides Gas

On February 24, the Montana Supreme Courtroom issued its choice in Petrich Household Restricted Partnership v. Trout Limitless (2026 MT 34), a case rooted within the decades-old adjudication of water rights on Mill Creek in Park County.

Mill Creek is a key tributary of the Yellowstone River and a supply of spawning habitat for Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri). Additionally it is, in line with FWP, chronically dewatered—a stream the place irrigation claims already exceed bodily out there provide. The case centered on whether or not landowners might develop the interval of use for water rights initially decreed as “flood water” claims, restricted to the Might 1 by means of July 15 window when excessive flows make extra water out there.

Trout Limitless had objected to the claims throughout Montana’s common water adjudication, arguing that producing new “implied” water rights to increase use past the decreed interval would improve the burden on an already over-appropriated stream. The Clark Fork Coalition filed an amicus temporary supporting TU’s place, warning that the Water Courtroom’s strategy to implied claims might set a precedent permitting irrigators throughout the state to develop their diversions on the expense of instream flows.

The case is technically a water adjudication dispute, however its implications ripple outward. For anglers who fish Mill Creek or the Yellowstone River mainstem beneath it, the query of how a lot water stays within the channel throughout late summer season immediately determines whether or not cutthroat trout can spawn, rear, and transfer between tributaries and the river.

What It Means for Anglers

These developments sit on the intersection of two pillars that outline Montana fly fishing: stream entry and water. Montana’s Stream Access Law of 1985 stays among the many strongest within the nation, guaranteeing leisure use of all floor water beneath the abnormal high-water mark. Nook crossing is, in some ways, stream entry’s landlocked cousin — the query of whether or not the general public can bodily attain the water it already has the best to make use of.

The sensible upshot for anybody planning a 2026 season: nook crossing in Montana stays legally murky. FWP wardens will proceed referring suspected circumstances to county attorneys, although no corner-crossing prosecution has gone to trial in current reminiscence—fees stemming from a 2021 incident involving a Townsend bowhunter have been dropped in 2023 simply because the case was headed to a jury. Anglers and hunters who select to cross at checkerboard corners accomplish that at their very own threat, and the chance varies county by county.

On the water facet, Mill Creek and streams prefer it throughout the Yellowstone basin face continued strain from agricultural withdrawals, and the Petrich ruling could form how aggressively these claims develop. Trout Limitless’s water program, which has pursued settlements on Mill Creek water rights since 2019, will possible weigh the choice’s implications earlier than figuring out subsequent steps.

One factor is evident: the strain between public entry and personal property rights in Montana is just not resolving itself. Whether or not the reply comes from the legislature, the courts, or some mixture of the 2, the result will decide what Montana’s public waters appear to be for a era.
