2025 Montana Legislative Session
The 2025 Montana legislative session, which began in January, will address key environmental and water quality issues, including water rights, pollution control, and the protection of natural water resources. Given Montana’s reliance on clean water for agriculture, recreation, and ecosystems, these issues are a critical focus. The Clark Fork Coalition is closely monitoring the bills being considered and will provide updates on their potential impact on our watershed. Stay informed, take action, and learn how to contact legislators through our bill trackers, which highlight key bills to watch during this session.
End of Session Recap On Priority Bills
The Good
SB 190 – Derek Harvey (D)
CFC SUPPORTED (BILL PASSED): SB 190 allows water users to voluntarily file a written consent to waive the adverse effects analysis requirement when applying for water right permits, changes in appropriation rights, or temporary changes in water rights. CFC utilizes the water right change process to temporarily convert irrigation water rights to instream flow on dewatered streams throughout the Clark Fork Basin. SB 190 will streamline this change process and improve our ability to complete important flow restoration projects on key streams and rivers.
HB 580 – Josh Seckinger (D)
CFC SUPPORTED (BILL PASSED): In Montana, water rights are subject to the law of abandonment, meaning that an irrigator who stops diverting irrigation water for an extended period of time could potentially be accused of abandoning his/her water rights. HB 580 clarifies the law to make sure that water users who voluntarily choose to stop using water during a drought and in compliance with a local, state or regional drought management plan cannot be subject to claims of “abandonment” of their water rights. CFC supports this common-sense policy change, which will encourage users to make voluntary decisions to conserve water and help protect streamflows during periods of intense drought.
SB 472 – Denley Loge (R)
CFC SUPPORTS (BILL IN SENATE): HB 472 increases the civil penalty for violation of the Montana Streambed Preservation Act. CFC supports this bill because it will effectively deter more individuals from undergoing projects that could impact our streams and rivers without receiving approval from the Board of Supervisors for the local Conservation District. The bill still allows the Board to work with an offending party to resolve a dispute before collecting the civil penalties.
SB 178 – Sue Vinton (R)
CFC SUPPORTED AS AMENDED (BILL PASSED): This bill will create a new tool that could be used by CFC to combat dewatering within the basin. The bill creates a new, short-term water leasing tool that promotes voluntary, temporary leases of water rights for a new proposed beneficial use. The leases would be short-term (40 days annually) and cannot be used more than 5 out of every 10 years but are otherwise exempt from receiving a “change of use” authorization from DNRC.
SB 358 – Wylie Galt (R)
SB 436 – Carl Glimm (R)
SB 186 – Barry Usher (R)
HB 704 – Mike Vinton (R)
HB 658 – Jedediah Hinkle (R)
The Bad
HB 256 – Ken Walsh (R)
CFC SUPPORTED (BILL FAILED): HB 256 would’ve created a new state special revenue account for water development, and seeded the trust with $50 million from general fund in 2025 and an additional $50 million in 2026. The bill would’ve required a portion of the earned interest to fund water storage pilot projects aimed at increasing water storage for beneficial uses. CFC has several potential water storage projects under development aimed at boosting streamflows on dewatered streams in the Clark Fork Basin. The bill received overwhelming support in the House but ultimately failed in the House Appropriations Committee.
The Ugly
HB 664 – Bill Mercer (R)
CFC OPPOSED (BILL PASSED): HB 664 would repeal Montana’s numeric water quality standards for nutrients that were adopted in 2014, eliminate the Nutrient Work Group and attempt to revert the state’s WQS to narrative standards for nutrient pollution. These numeric nutrient standards have a proven track record of success in the Clark Fork Basin and offer the best path for protect our state’s water resources from harmful nutrient pollution. CFC opposes HB 664 because it would Montana’s numeric nutrient standards without a clear plan for replacement, without any scientific basis for the rollback, and without submitting the proposed changes to the EPA for approval as required by the CWA. The bill passed both houses. CFC will ask Gov. Gianforte to veto the bill.
HB 685 – Steve Fitzpatrick (R)
CFC OPPOSED (BILL PASSED): In some cases, Montana DEQ can grant permission for a proposed project (such as a mine) to negatively impact water quality in a given stream or river. In order to do so, DEQ must (among other things) balance the economic or social benefits of a proposed project with the costs of allowing degradation of our high-quality waters. HB 685 eliminates this requirement. Instead, it would require DEQ to simply determine whether the proposed project will result in economic development “in the area that the high-quality waters are located.” CFC opposes this bill because it will make it easier for DEQ to authorize degradations of our high-quality waters. The bill passed both houses. CFC will ask Gov. Gianforte to veto the bill.
