Visitors being advised to avoid swimming in Overton Arm
Boulder City, NV (KTNV) -- A foamy substance and a number of dead carp have been observed in the Overton Arm of Lake Mead.
The substance appeared to be coming from the mouth of the Virgin River and spanned approximately eight miles down to Echo Bay.
"Until we know for sure what is creating the foam and what is causing the fish to die, we advise people to stay out of the water in the Overton Arm," said Christie Vanover, park spokesperson.
The Southern Nevada Water Authority is working with the National Park Service to acquire water samples.
