Montana AIS Inspection Stations Intercept 19 Boats

As of June 30, more than 44,000 watercraft have been inspected. Watercraft inspection stations are busier than ever, with early season numbers higher than previous years. Out of state boat traffic is also higher, presenting an elevated risk of AIS transported into the state.

Inspectors have intercepted 19 mussel fouled vessels at the Anaconda, Dillon, Flowing Wells, Hardin and Nashua watercraft inspection stations.

Watercraft inspection data is available on the AIS Dashboard and will be updated weekly.

AIS Monitoring Update

The AIS monitoring team has begun collecting AIS early detection samples for the 2020 season.

  • To date, 389 of 435 collected samples from Montana have been analyzed for mussel veligers.
  • For Tiber reservoir 19 samples have been analyzed so far this season with no dreissenid veliger detections.
  • Faucet snails were identified in two new locations in northwestern Montana in Smith and Lost Coon Lakes. Faucet snails are known to occur in the Flathead Basin as well as several other locations in the state.
  • FWP is working with the Custer Gallatin National Forest to eradicate curlyleaf pondweed (CLPW) in three newly acquired ponds on Slip and Slide Creek near Gardiner. Because the dams are at risk of failure, the Forest Service plans to drain the ponds and they are taking precautions to reduce the spread of the weeds downstream. This is the only known population of CLPW within the Yellowstone River Drainage in Montana.
