All
out-of-state boats and
resident boats that go out-of-state and return to Colorado
must pass a state-certified inspection for zebra mussels and other aquatic nuisance species prior to launching in any Colorado lake, reservoir or waterway.
In addition, boats that have launched on any of the Colorado lakes or reservoirs where mussels have been detected must pass an inspection before launching at a new location. See the
Mandatory Boat Inspections page for complete details.
Zebra and quagga mussels are small, non-native barnacle-like mollusks with dark and light colored stripes. They damage equipment by attaching to boat motors or hard surfaces and clog water treatment facilities.
Public awareness and participation is the best weapon in the containment of invasive species. Boaters are reminded to take the simple precaution of making sure that they Clean, Drain, and Dry their boat when they leave the lake.
