Unexpectedly larger numbers of an invasive mussel species have turned up at southern Utah's Lake Powell, prompting state and federal officials to ramp up ongoing boat inspections and decontamination procedures.
Denise M. Shultz, spokeswoman for the Glen Canyon National Recreation Area, said Tuesday that the numbers of adult Quagga mussels found at the lake by the National Park Service and Utah Division of Wildlife Resources came as water levels at Lake Powell have dropped and exposed previously underwater shorelines.
"Thousands of adult Quagga mussels have been found in various locations, such as canyon walls, Glen Canyon Dam, boats, and other underwater structures," Shultz stated. "The majority of mussels found are isolated adults, with additional groupings of small clusters. One adult mussel was found on the south canyon wall of Bullfrog Bay."
