DNA fragments from zebra mussels have been detected in Utah’s section of the Colorado River for the first time, raising new concerns for the river because of the challenges that the species is associated with. The DNA fragments were found within four of 22 samples collected in June and July near the Potash Boat Ramp, nearly 15 miles downstream of Moab, Utah Division of Wildlife Resources officials said in a statement on Tuesday. It follows an infestation that was found last year near Loma, Colorado, just upstream of the Utah-Colorado border. Zebra mussels, much like quagga mussels, which have been an issue at Lake Powell, are invasive and clog pipes and infrastructure, while also creating new hazards on rocks and beaches, potentially causing millions in damage.
