Update: This is an extended version of the story we posted Thursday, Oct. 12, the original text is at the bottom of this post.
Along a rocky shoreline at Canyon Ferry Reservoir Thursday, if you listened closely, you could hear the sound of a dog sniffing, using its nose to search for invasive mussels threatening to overrun Montana waters.
Hilo, a three year old black lab, isn’t finding any evidence of the adult quagga or zebra mussels he’s been sent to search for along the shoreline.
