Quagga and Zebra Mussels-What to expect this summer in the ANRA

boat inspection stations



Get your Boat Inspected

Sulphur Ranger District and the Arapaho National Recreation Area have been cooperating with Colorado Parks and Wildlife for the past three years to prevent aquatic nuisance species from being spread or introduced into Lake Granby and Shadow Mountain Reservoir.

This cooperative effort has helped educate the public on the threats and consequences aquatic nuisance species pose to the water bodies where they recreate. 

Last year, CPW completed more than 15,000 inspections and disinfected more than 1,300 boats at the inspection stations.  For the third year in a row, surveys to detect the presence of quagga and zebra mussels in these lakes came up negative. 

This cooperative effort will continue in 2012. Boat inspections on Lake Granby, Shadow Mountain Reservoir and Grand Lake begin Saturday, May 12. Grand Lake, Green Ridge, Stillwater and Sunset boat launch areas will have inspections open from 6 a.m. to 8 p.m. daily.

Once Arapaho Bay campground and boat launch open, inspections will be open 8 a.m. to 6 p.m., Friday to Sunday.  The boat ramp will open simultaneously with the Roaring Fork Campground at noon on May 25.

Highland, Beacon Landing, Grand Elk and Trail Ridge marinas in the Arapaho National Recreation Area and Boater’s Choice and Headwaters marinas in Grand Lake also cooperate in these joint efforts.

If you remove your boat during the night when inspections are not in place, it is your responsibility under Colorado law to ensure your vessel is inspected by a state certified inspector before you launch in any Colorado water.*

We need your help. Please act responsibly for your Colorado waters and get your boat inspected. Remember to leave yourself extra time when planning your trip.

Hand-launched crafts, including kayaks, rafts, canoes and belly boats are not considered high risk for mussels and may launch without an inspection. These non-motorized vessels may use the Hilltop and Willow Creek Reservoir boat launch sites.

*“All persons transporting a vessel or other floating device from a water of the state known to be infested…must be inspected prior to leaving the infested water, or if state authorized inspection facilities are not open or otherwise available, must be inspected prior to launch in any other water of the state.” (Chapter 8, Section 803 (B))

Remember to Drain Clean and Dry

Help stop the spread of Quagga and Zebra Mussels

Before moving to new waters:

·         Drain every drop of water from every part of your boat or water craft.

·         Clean everything that came in contact with the water. This includes removing plants and mud.

·         Dry everything that came in contact with the water: motors, jet drives, live weeds, boat hulls, boots, bait buckets, swimming floats, etc. Let it dry at least five days if changing to new waters, two weeks if leaving infested waters
