CRATER LAKE, Ore. — The fear of invasive species has prompted Crater Lake National Park officials to close the lake to scuba divers.

Crater Lake will be closed until the administration can develop rules to prevent microscopic species, such as quagga mussels, spiny water fleas and viruses, don’t hitchhike into the water on diving gear.

Park Superintendent Craig Ackerman says the lake is becoming more popular with divers, raising the threat that some new creature could invade the lake ecosystem and change it forever.
