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.
