Dead Pelicans, More Mussels Found in Montana This Week Two separate incidents are raising concerns with Montana Fish, Wildlife and Parks officials. Let's start with the good news/bad news scenario. Good news that FWP is finding boats carrying invasive mussels. Bad news that they've already found more this year than in all of 2020. More incoming boats carrying more mussels increases the likelihood that a few could slip through and potentially plague Montana waters. This past Sunday, June 27, watercraft inspection stations in eastern Montana intercepted two boats entering the state carrying invasive mussels, making it the 35th and 36th mussel-fouled boats intercepted this year. This surpasses the total number of 35 mussel-fouled boats intercepted in 2020.
