Boaters traveling from water body to water body, and travelers passing through the state may have noticed something new this summer.
Mandatory boat check stations are not new to the state, but increased funding means there are more of them.
Aquatic Invasive Species Specialist Linnaea Schroeer with Fish, Wildlife and Parks said the state set up 20-mandatory check stations this summer, up from 16 the year before.
She said Montana is one of only 5-states free of zebra and quagga mussels.
The others include Washington, Oregon, Idaho, and Wyoming.
