Non-Native Snail Turns Up in Truckee River

RENO, Nev. (AP) - A non-native snail has turned up in the Truckee River in Nevada for the first time, and wildlife officials are hoping it doesn't harm the river's trout population.

Nevada Department of Wildlife officials say tests have confirmed that three New Zealand mudsnails are living in at least a one-mile section of the river in Sparks.

They told the Reno Gazette-Journal that a single mudsnail can produce a colony of up to 40 million snails in a single year, and ruin a stream's ecosystem.

But wildlife officials say it's unknown whether the river that flows from Lake Tahoe to Pyramid Lake will provide ideal conditions for the mudsnails to multiply in such large numbers.

Since 1987, the snail has invaded rivers and lakes across much of the West, including southern Nevada's Lake Mead.
