The Colorado River is officially positive for invasive zebra mussels

The species has the potential to impact drinking water for millions of people.

The invasive zebra mussel species is spreading across Colorado and could eventually impact drinking water, agriculture and ecosystems if they aren’t eradicated — something experts say is really hard to do. 

Colorado Parks and Wildlife announced July 3 that several new colonies of the species were discovered this summer in Eagle County and the Colorado River near New Castle and Highline Lake State Park. The additional detections mean the river is now considered “positive” for the species from the confluence of the Roaring Fork River north of Aspen to the Colorado-Utah border.
