Atmospheric river drives flooding in northwest Montana

Warm temperatures and an “atmospheric river” of precipitation that flowed into northwestern Montana this week have generated a state of emergency in Montana’s northwesternmost county, Lincoln, as local waterways run unseasonably high.

Around 12 p.m. Wednesday, the National Weather Service started issuing flooding watches as area snowpack sites reported 24-hour precipitation totals that were approaching record levels. NWS meteorologist Dan Borsum told Montana Free Press Thursday that the “rain-on-snow” nature of the recent precipitation has led to widespread flooding.

Borsum called the weather pattern “unusual” for mid-December, instead likening it to a warm April.

Zach Sherbo, the public health manager for the Lincoln County Health Department, said in a Thursday afternoon phone call that additional precipitation is expected through Thursday evening, so rivers could continue rising into Friday.

The Lincoln County communities of Libby and Troy have been hit the hardest by the deluge, which prompted emergency services personnel to issue a state of emergency Thursday afternoon. Residents are cautioned against unnecessary travel and those served by the Libby city water supply are under a boil-water order as a precaution in the event of water supply contamination. School has also been canceled for students in Libby and Troy, Sherbo said.

The Lincoln County Sheriff’s Department has identified a handful of bridges that have been compromised or are washed out as a result of flooding. It suggests residents looking for information on road closures and bridge conditions review an interactive map that is available online and linked in a press release posted to the Lincoln County Health Department’s Facebook page.

“It’s going to take a long time to recoup from this, just structurally, just with the bridges we’ve lost already and the condition that they’re in and going toward,” Sherbo said. “It’s a pretty big combined local effort right now.”

Justun Juelfs, the Kalispell-area maintenance chief with the Montana Department of Transportation said three stretches of state-managed roadways were closed or under monitoring status as of 4 p.m. Thursday.

An approximately 80-foot section of the Farm to Market Road south of Libby has washed out as Libby Creek carved a new channel. MDT is also monitoring erosion that is occurring along a U.S. Highway 2 bridge southeast of Libby and along a section of Highway 56 near Bull Lake. Juelfs encouraged motorists to review MDT’s road conditions report for up-to-date information on impacts to state highways.

The Army Corps of Engineers is assisting with sandbag-filling and distributing efforts and the Red Cross has set up a shelter for those in need at the Assembly of God Church in Libby, according to Sherbo.

The Montana Disaster and Emergency Services agency is also lending a hand with the flood response. In an email to MTFP, Anette Ordahl with DES wrote that a district field officer and a recovery coordinator are on the ground in Libby to offer assistance.

In a Thursday afternoon press release, Gov. Greg Gianforte noted that Sanders and Flathead counties have also recognized the flooding by issuing emergency or disaster declarations. Up to four inches of additional rainfall are expected across western and south-central Montana, according to a disaster declaration Gianforte’s office included in a 3 p.m. press release.

The National Weather Service reported Thursday morning that the Bear Mountain snowpack monitoring site, located just across the border in Idaho, received 6.5 inches of precipitation as of this morning, making it the third-wettest 24-hour period for the site in its 44-year monitoring history. The six-day precipitation total for Dec. 6-11 is 13 inches.

Borsum, with the National Weather Service, said the recent, unseasonable warm spell in western Montana combined with the “super strong” atmospheric river to melt early season snowpack and drive flooding. A similar rain-on-snow event in early June of 2022 led to widespread flooding in parts of south-central Montana that required extensive repairs to roadways and bridges.

Thursday, the Yaak River near Troy surpassed its official flood stage, running at more than 7,500 cubic feet per second. Its usual volume for this time of the year is about 200 cfs.

The Fisher River near Libby was also nearing flood stage. As of Thursday afternoon, it was running at nearly 4,000 cfs, more than 20 times its usual volume for mid-December.

Apparent AI Glitch in Filing by Montana Public Defender, Recent Congressional Candidate

Apparent AI Glitch in Filing by Montana Public Defender, Recent Congressional Candidate

Everyone makes mistakes, even experienced professionals; a good reminder for the rest of us to learn from those mistakes. The motion in State v. Stroup starts off well in its initial pages (no case law hallucinations), but is then followed by several pages of two other motions, which I don’t think the lawyer was planning to file, and which appear to have been AI-generated: It begins with the “Below is concise motion language you can drop into …” language quoted above.

Griffen Smith (Missoulian) reported on the story, and included the prosecutor’s motion to strike that filing, on the grounds that it violates a local rule (3(G)) requiring disclosure of the use of generative AI:

The document does not include a generative artificial intelligence disclosure as required. However, page 7 begins as follows: “Below is concise motion language you can drop into a ‘Motion to Admit Mental-Disease Evidence and for Related Instructions’ keyed to 45-6-204, 45-6-201, and 4614-102. Adjust headings/captions to your local practice.” Page 10 states “Below is a full motion you can paste into your pleading, then adjust names, dates, and styles to fit local practice.” These pages also include several apparent hyperlinks to “ppl-ai-file-upload.s3.amazonaws,” “ppl-ai-fileupload.s3.amazonaws+1,” and others. The document includes what appears to be an attempt at a second case caption on page 12. It is not plausible on its face that any source other than generative AI would have created such language for a filed version of a brief….

There’s more in that filing, but here’s one passage:

While generative AI can be a useful tool for some purposes and may have greater application in the future, when used improperly, and without meaningful review, it can ultimately damage both the perception and the reality of the profession. One assumes that Mr. Stroup has had, or will at some point have, an opportunity to review the filing made on his behalf. What impression could a review of pgs. 12-19 leave upon a defendant who struggles with paranoia and delusional thinking? While AI could theoretically one day become a replacement for portions of staff of experienced attorneys, it is readily apparent that this day has not yet arrived.

The Missoulan article includes this response:

In a Wednesday interview, Office of Public Defender Division Administrator Brian Smith told the Missoulian the AI-generated language was inadvertently included in an unrelated filing. And he criticized the county attorney’s office for filing a “four-page diatribe about the dangers of AI” instead of working with the defense to correct her mistake.
“That’s not helping the client or the case,” Smith said, “and all you are doing is trying to throw a professional colleague under the bus.”

As I mentioned, the lawyer involved seems quite experienced, and ran for the Montana Public Service Commission in 2020 (getting nearly 48% of the vote) and for the House of Representatives in Montana’s first district in 2022 (getting over 46% of the vote) and in 2024 (getting over 44%). “Его пример другим наука,” Pushkin wrote in Eugene Onegin—”May his example profit others,” in the Falen translation.

Thanks to Matthew Monforton for the pointer.

Montana Department of Agriculture focusing on innovation in 2026

HELENA — You probably have goals and plans for 2026—the Montana Department of Agriculture does too.

“We’re really focusing on innovative agricultural practices,” Montana Department of Agriculture director Jillien Streit said.

It’s no secret that agriculture—farming and ranching—is not easy. There are long days, planning, monitoring crops and livestock, and other challenges beyond farmers’ and ranchers’ control.

“We have very low commodity prices across the board,” Streit said. “We still have very high input prices across the board, and we have really high prices when it comes to our equipment, and so, it’s a really tough year.”

But innovation, including new practices, partnerships and technology use, can help navigate some of those challenges.

“We can’t make more time and we can’t make more land, so we need to start putting together innovative practices that help us maximize what our time and land can do,” Streit said.

Practices range from using technology like autonomous tractors and virtual fencing—allowing rangers to contain and move cattle right from their phones—to regenerative farming and ranching.

“It is bringing cattle back into farming operations to be able to work with cover cropping practices to invigorate the soil for new soil health benefits,” Streit said.

The Montana Department of Agriculture is working to help producers learn, share, and collaborate on new ideas to work in their operations.

The department will share stories of practices that work from farms and ranches across the state. Also, within the next year or so, Streit said the department is hoping to roll out technology to help producers collaborate.

“(It’s) providing a communication platform where people can get together and really help each other out by utilizing each other’s assets,” she said.

While not easy, agriculture is still one of Montana’s largest industries, and Streit said innovating and sharing ideas across the state can keep it going long into the future.
