Some boats coming into Montana from Lake Powell will be locked to their trailers for a mandatory quarantine period of up to 30 days in response to the threat of invasive mussels.

All boats coming into Montana are already required to be inspected for invasive species like zebra and quagga mussels, which have caused millions of dollars of damage to hydropower dams, irrigation systems and personal property in infested waters in other states.
