Mandatory -This boating season brings with it mandatory state-certified boat inspections to help prevent the spread of zebra and quagga mussels and other aquatic invasive species (AIS) in Colorado lakes and reservoirs. See the List of Statewide Watercraft Inspection and Decontamination Sites.
Boaters should be clean, drained and dry in between each time they launch their boat.
You must pass a state-certified boat inspection if:
You have traveled outside of the state to boat.
You have launched on any of the Colorado lakes or reservoirs where mussels have been detected. You must submit to an inspection for aquatic nuisance species prior to leaving the body of water.
You enter a reservoir where inspections are required. See the List of Statewide Watercraft Inspection and Decontamination Sites. Boaters should expect to be inspected at any lake or reservoir in the state.
You must pass a state-certified boat inspection if you plan on launching in any Colorado lake, reservoir or waterway.
How to Help Prevent the Spread of Invasive Species
Zebra and quagga mussels are a serious threat to Colorado waters. Invasive species such as the zebra mussel negatively influence the food chain for native fish. Zebra mussels remove major quantities of phytoplankton from the water. Phytoplankton is food for larval and juvenile fish. To learn more about the negative affects of aquatic nuisance species, visit 100th Meridian Initiative and Protect Your Waters.
To help prevent the spread of zebra and quagga mussels, boaters should remember to follow these steps: Clean, Drain, Dry.
Check your boat and trailer every time before you transport your boat. Overland transport of boats, motors, trailers and other watercraft poses the greatest risk for spreading zebra and quagga mussels. Adult mussels can attach or “hitchhike” to any surface and can live several days out of water (depending on the time of year) in moist, shaded areas. The microscopic mussel larvae (known as veligers) can be transferred in water contained in live wells, bilge, ballast tanks or “minnow” buckets. Check out these educational catchy tunes that offer listeners tips on preventing the spread of aquatic invasive species.
To help the Colorado Parks and Wildlife quickly identify new populations of this unwanted species please report any sightings to Elizabeth Brown, Invasive Species Coordinator.
