Montana Fish, Wildlife and Parks intercepted 14 boats this summer carrying an invasive mussel that has the potential to topple Montana’s recreation economy.

An invasive mussel prevention plan is creating conflict between some recreational boaters and resource managers over access to Tiber Reservoir.

Tiber is the only lake in the state that’s tested positive for invasive mussels two years in a row.

Some boat launches on Tiber Reservoir will be closed this summer to lessen the likelihood of contaminating other Montana lakes and rivers with invasive mussels.

Boaters will only be able to launch from the Tiber Marina and the VFW Campground, where inspectors will be on hand to check for invasive hitchhikers before and after launch, and decontaminate boats if necessary.

That green and brown gunk is a mix of algae, plankton and bits of genetic material that hold the answer to whether Flathead Lake has mussels in it. One sample comes from 9 meters deep, the other from the surface.

Montana Fish, Wildlife and Parks Thursday announced it detected additional evidence of invasive mussels in one eastern Montana reservoir last summer. The detection raises a few red flags.

FWP found microscopic invasive baby mussels in Tiber and Canyon Ferry Reservoirs for the first time in the fall of 2016. But the state agency and its partners didn’t find any last summer.

This sign from Minnesota gives a glimpse into one possible future if invasive mussels become established in Montana.

This is "SubSurface: Resisting Montana’s Underwater Invaders." I’m Nicky Ouellet, and in our first episode I’m taking us to the Midwest, to lakes where people have been fighting invasive zebra and quagga mussels for decades, to hear, see and smell what could become Montana’s mussel-encrusted future if a full-blown infestation happens here. These stories are reporting from the future.
