Montana Fish, Wildlife & Parks delisted Canyon Ferry Reservoir as an invasive species management area in 2020. Following three years of no invasive mussel detection, regional guidelines allow for the delisting of a suspect waterbody and the removal of the mandatory exit inspection requirements.
The restrictions on Tiber Reservoir will remain in place for one more year. The Certified Boater Program will also continue.
Boat ramps located around Tiber Reservoir are open to “certified boaters.” The map below indicate the current status of each boat ramp on these waterbodies.
YES: If you frequently boat on Tiber Reservoir without traveling to other waterbodies between visits.
YES: If you own a boat that takes longer to decontaminate, like wake boats or boats that have a ballast.
YES: If you are a Montana resident living EAST of the Continental Divide AND your watercraft is registered in Montana.
NO: If you frequently boat on many different waterbodies.
NO: If your boat is kept at a dock or slip and doesn’t leave the reservoir.
NO: If you reside west of the continental divide OR outside the state of Montana, you are not eligible for the program.
NO: If your vessel is not registered in Montana.
NO: If you are a rental shop.
You can complete the certification process online. You must read the tutorial, pass the test, complete a registration form, and sign a contract agreeing to abide by the Certified Boater rules. Remember, you'll need your vessel and trailer licenses numbers and description of all vessels to complete certification. Your Certified Boater decals will be mailed to you within 5-working days.
If you want to complete the certification in person, you will need to travel to the FWP Region 4 office in Great Falls (4600 Giant Springs Road) to complete the certification process and receive your decals. Remember to bring your vessel and trailer licenses numbers and description of all vessels.
You will be issued up to 3 decals. Place 2 decals on the back/stern of your boat, one on each side. If your boat is on a trailer, place 1 decal on the trailer’s back bumper or fender where it is visible when parked.
Inner tubes (motor vehicle type)
Air mattresses/water toys
Float tubes (belly boats)
If you want to launch at a different waterbody, go to a decontamination station at Tiber Reservoir.
Your boat will be cleaned, sealed, and you will be given a receipt of inspection. Keep your receipt.
If you encounter an inspection station during your travels you are required to stop.
If you travel west over the Continental Divide you are required to get an inspection.
If you travel out-of-state you must be inspected before launching in Montana waters.
If selling your boat or trailer you must remove all Certified Boater decals. The new owner must complete the Certified Boater program.
If loaning your boat or trailer you must ensure the borrower knows and follows the rules of the Certified Boater program.
