Montana’s waterways are getting stronger protections thanks to a new bill aimed at enhancing aquatic invasive species (AIS) prevention efforts. House Bill 829, introduced in the 69th Montana Legislature, proposes sweeping updates to how the state educates, monitors, and penalizes those using Montana’s lakes and rivers.
Key Highlights of HB 829
Mandatory AIS Awareness Training
Starting January 1, 2026, anyone seeking an Aquatic Invasive Species Prevention Pass—required for both motorized and nonmotorized vessels—must complete a state-approved AIS awareness course. The Montana Department of Fish, Wildlife & Parks will develop a 30-minute training that includes:
- An educational video
- A test based on the video content
This training will focus on how to prevent the spread of invasive species, current Montana regulations, and pre-launch inspection requirements.
AIS Prevention Pass Now Required for All Vessels
The bill extends AIS prevention pass requirements to include all nonresident watercraft, including:
- Motorized vessels ($30 annual fee)
- Nonmotorized vessels like kayaks, rafts, drift boats, and sailboats ($10 annual fee)
These passes must be physically or digitally accessible for inspection by officials and are valid for one calendar year. The funds collected go directly to Montana’s invasive species management programs.
Tougher Penalties for AIS Violations
Montana is stepping up enforcement:
- Negligent violations carry fines of up to $500 for the first offense and $750 for repeat offenses.
- Knowingly introducing AIS is now a felony, punishable by up to 2 years in prison and a $10,000 fine.
- Offenders may lose their fishing license and vessel privileges, and in severe cases, surrender their boat and pay restitution.
Civil penalties for other violations have also been raised to a maximum of $25,000.
Looking Ahead
With the new law taking effect in 2026, Montana officials are emphasizing early education and public outreach. Whether you’re a weekend paddler or a seasoned angler, expect to see more resources—and more accountability—on the water.
