National Park Service to set new rules to protect pristine waters against invasive species

SUMMIT COUNTY — With growing concern about the environmental impacts of
invasive species to freshwater ecoysystems, the National Park Service has decided to close the pristine waters of Crater Lake National Park to scuba diving.
Some scientists consider Crater Lake to be the most pristine naturally occurring large body of water on the planet. Minor changes in the hydrologic conditions of the lake could permanently affect both purity and clarity. Invasive species are almost impossible to eliminate once they’ve been introduced, at least without massive chemical intervention that would likely have other unwanted consequences.
