More Invasives Found in State Waters

Biologists with Colorado Parks and Wildlife say they continue to find new signs of aquatic invaders in Colorado waters, including New Zealand mudsnails, which showed up in East Delaney Butte Reservoir this summer. They also found Eurasian watermilfoil, an invasive aquatic weed in the reservoir at Eleven Mile State Park, and rusty crayfish, discovered in 2009 in the headwaters of the Yampa River, have been recently confirmed in the reservoir at Stagecoach State Park. “We have had success with our boat inspection programs to prevent invasive species, but there are a few aquatic nuisance species that can spread via methods other than boats,” said Elizabeth Brown, an invasive species coordinator with parks and wildlife. “The fact that we’re finding new populations means we have to work harder to engage the public to do their part to clean and dry all their gear and equipment as well as their boats to protect our waters.”
