Managing noxious weeds in Montana
Montana law states that “it is unlawful for any person to permit any noxious weed to propagate or go to seed on the person’s land.” It further states that “…any person who adheres to the noxious weed management program of the person’s weed management district or has entered into and is in compliance with a noxious weed management agreement” is considered to be in compliance. (Montana Code 7-22-2116 (2023)).
Legally, a noxious weed is any plant designated by a Federal, State or county government as injurious to public health, agriculture, recreation, wildlife or property. Montana Noxious Weed List includes 36 plant species ranging in priority from 1A and 1B to 2B, and five regulated plant species.
The first step in any well executed project is to identify the goals and create a plan that is both realistic and effective. Managing noxious weeds begins with plant species identification, includes taking an inventory of the level of infestation, and involves creating an action plan that is viable.
Invasive plants thrive on disturbed soil and seeds are distributed by many vectors including birds, wind, wildlife, livestock, humans and all sorts of vehicles. Some invasives also have aggressive root systems that spread long distances, often from a single plant. Noxious weeds and other non-native invasives left untreated become established, quickly reproduce and spread and cause harm to the environment as well as the economy. Invasive species compete directly with native and desirable species for moisture, sunlight, nutrients and space. Populations unchecked cause major change faster than native ecosystems can accommodate.
The most effective approach to controlling noxious weeds is the implementation of integrated weed management (IWM), the integration of effective, dependable and workable weed management practices such as cultural (e.g. pulling weeds), mechanical (e.g. mowing), chemical and biological that can be used economically.
Powell County Weed District and Missoula County Department of Ecology and Extension work with land owners and managers to promote IWM practices including site visits and vegetation management plan development, loaner equipment programs, cost-share grants, revegetation tools, biological control with insects, organized weed pull events, outreach and education events and no-cost materials such as weed ID books. We offer plant identification and also provide contact information for licensed spray contractors and other resources that promote healthy land use practices.
I would encourage anyone seeking advice on noxious weed management to contact their local county weed board coordinator or Ag Extension Agent. County coordinators and Ag Extension agents are trained and licensed and provide the most accurate and up to date options and resources for managing noxious weeds.

Public Meeting at Hub on Smith Concerning Montana Water Call Prompting Priority Administration in Tongue Basin
Wyoming State Engineer Brandon Gebhart announced that on May 5, 2026, the State of Montana placed a call under Article V(A) of the Yellowstone River Compact to fill Tongue River Reservoir in Montana. As a result, priority administration is in effect on post-1950 water rights in Wyoming that divert water from the Tongue River and its tributaries and are not excluded from the compact.
A public meeting will be held from 5:30 to 6:30 p.m. Monday, May 18, in the dining room of The Hub on Smith. Attendees are asked to enter on the north side of the building.
The Tongue River Basin has been experiencing drought conditions over the past year with historically low winter snowpack and streamflow conditions. According to the release, those conditions led to Montana’s interstate call and prompted the administration of the Tongue River Basin in Wyoming.
The priority administration will affect post-1950 water rights within the Tongue River Basin, including reservoir storage, stream diversions and groundwater withdrawals, all of which affect river flows. Post-1950 water rights will be regulated off or prevented from turning on. Wyoming hydrographer-commissioners will continue to administer reservoir storage and post-1950 diversions throughout the spring and work with affected water users until the administration is lifted.
As provided in the compact, domestic uses less than one-half acre in area and livestock uses, including stock reservoirs less than 20 acre-feet in capacity, are excluded from this administration. The release noted these excluded rights could be subject to future regulation to satisfy priority calls by senior Wyoming water rights.
Beginning May 5, 2026, Wyoming hydrographer-commissioners have worked to record the current storage levels of reservoirs with post-1950 water rights. Going forward, those reservoirs can continue to accrue storage so long as post-1950 storage gained after the interstate call on May 5 remains in storage until either the water is released to satisfy the Montana call or Montana lifts the call because Tongue River Reservoir will fill.
Reservoirs with unfulfilled pre-1950 water rights can continue to store water and that storage will not be subject to release to satisfy Montana’s call. However, that storage and other direct flow rights could be subject to regulation to satisfy priority calls by senior Wyoming water rights.
The priority administration will be carried out pursuant to state law by hydrographer-commissioners assigned to various portions of the Tongue River Basin, working under the direction of Division II Superintendent David Schroeder.
The Wyoming State Engineer’s Office can be contacted at:
Jack Morey, deputy state engineer, 307-777-5032, jack.morey2@wyo.gov
David Schroeder, Division II superintendent, 307-674-7012, d.schroeder@wyo.gov
