Montana Aquatic Invasive Species Update: January 2024
Friends and Colleagues,
Most watercraft inspection stations are now open for the season and AIS survey is ramping up. As we prepare for boating season remember to Clean Drain and Dry your boat every time you leave the water and to stop at all open watercraft inspection stations.
Here is a little more information on what is going on in Montana and throughout the region:
Watercraft Inspection:
- After this weekend, most watercraft inspection stations will be open in the state: Watercraft Inspection Information
- Watercraft inspection partners for 2024 include: The Confederated Salish and Kootenai Tribes, The Blackfeet Nation, Little Shell Tribe of the Chippewa, Missoula County, the City of Whitefish, Glacier National Park, Swan Lakers and the Lincoln, Flathead, Beaverhead, Big Horn, McCone, Garfield and Powder River Conservation Districts.
- Over 1,800 watercraft have been inspected so far this season with 7 mussel fouled vessels intercepted to date. More information on mussel fouled vessels this season in the table below:

Early Detection:
- The AIS Early Detection Labratory is geared up and ready for another busy season of sample analysis.
- AIS early detection seasonal staff training will occur in May. Following the training, state-wide AIS early detection survey state-wide for all major waters in the state.
- Partners involved with early detection survey and sampling include: The Confederated Salish and Kootenai Tribes, The Blackfeet Nation, Missoula County, The Central and Eastern Montana Invasive Species Team (CEMIST), The Flathead Biologicals Station, the Whitefish Lake Institute, Clearwater Resource Council, Yaak Valley Forest Council, Glacier National Park, US Bureau of Reclamation, US Army Corps of Engineers, Avista Corp and Conservation Districts state-wide.
- New AIS detections so far this season include:
- New Zealand mudsnails in Silver Bow Creek near Butte: DEQ contractors sampling benthic invertebrate identified New Zealand mudsnails (NZMS) in a new location in Silver Bow Creek near Butte. This population is approximately 25 miles upstream of a NZMS population that was identified last year near Warm Springs. FWP staff will conduct further surveys in the area in the coming weeks to determine snail distribution and density in the area.
- Mystery snails detected at Finley Point in Flathead Lake: Mystery snails are an aquarium snail that are found in many waters in the West, but until this point, have not been found in Montana waters. Mystery Snail Info. Two snail shells were found in this area over the last two years. Follow up survey in April verified live snails in the area.

Zebra Mussels are discovered in Lake Oahe this past week. – 1/4/2024
https://www.keloland.com/news/capitol-news-bureau/zebra-mussels-in-lake-oahe/
This doesn’t come as a complete surprise as the Aquatic Invasion Species (AIS) has been detected in Lake Pactola and is considered infested with Zebra Mussels. Walleyes Unlimited of Montana is working with the Montana FWP and other organizations to combat the introduction of these into any Montana waters. We take a strong stance of promoting Clean, Drain, Dry and we all need to be vigilant in stressing this with any and all watercraft coming in from other area and now in particular the Dakotas.
You will be seeing and hearing a strong campaign in the very near future.
Thanks for all of your efforts and working together will be essential to keep these extremely damaging things out of our waters.
2020-2022

Montana Fish, Wildlife & Parks officials said that aquatic invasive species inspection stations and roving inspection crews are in operation at key border crossing sites, along major highways, and on heavily used water bodies.
The most likely aquatic invasive species threats to Montana waters include quagga and zebra mussels, New Zealand mudsnails, and Eurasian watermilfoil.
Plan ahead and get your watercraft inspected prior to launching if:
- You are coming into Montana from out-of-state.
- You are traveling west over the Continental Divide into western Montana (the Columbia River Basin).
- You are coming off Tiber or Canyon Ferry Reservoirs.
- Certified boaters must still follow the terms of their contract; they are required to get an inspection if they are travelling to another waterbody.
- Certified boater ramps will remain open ONLY to certified boaters.
- You are launching anywhere within the Flathead Basin and your watercraft last launched on waters outside of the Flathead Basin.

What you can do to help
- Ensure that you are not part of the problem
- Drain all water from your watercraft before leaving the immediate area of the lake
- Remove all weeds, mud or attached organisms from the boat and trailer
- Always dispose unwanted bait in the trash, never bring live bait into Montana without authorization
- Wash the exterior of your boat and trailer, hot-high pressure water is best
- Rinse and clean live wells, use hot soapy water or a weak bleach solution
- Allow boat to dry in between trips to different water bodies; ideally for 5 days
- Never move live fish, aquatic invertebrates or plants from one body of water to another without Fish, Wildlife and Parks authorization. It is unlawful to release any live aquarium or bait fish
- Report any potential sightings of zebra or quagga mussels (see description below) immediately to the Fish, Wildlife and Parks ANS Coordinator (406-444-2449), if possible, collect a sample, place it in a jar or zip-loc bag and note specific location and date
- Spread the word; tell your neighbors and friends about the importance of taking steps to prevent the spread of Aquatic Nuisance Species
- For further questions call the ANS Coordinator at 406-444-2449
How to identify Quagga or Zebra mussels
- Quagga and zebra mussels are similar in appearance
- Adults look like a small clam with a D-shaped shell
- Usually have alternating dark and light stripes, but these may not be present
- About the size of your fingernail, although can be up to 1-2 inches
- Small juveniles, which have just recently attached to a surface, look like black pepper and feel like sandpaper.
