No scuba diving in Crater Lake

Posted: Updated:

CRATER LAKE, Ore. Leave your scuba diving equipment at home if you're going to Crater Lake over Labor Day weekend. 

The National Park Service has temporarily closed the lake to scuba diving over the threat of invasive species.         

Park rangers say they'll keep the lake off limits to divers until they develop rules to be sure that microscopic species, such as quagga mussels, spiny water fleas and viruses, don't hitchhike into the pristine lake waters 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.         

Crater Lake is the nation's deepest and clearest lake, created 7,000 years ago by the collapse of a huge volcano.
