A story Monday about quagga mussels and New Zealand mudsnails mistakenly said mudsnails were found in Lake Tahoe. Mudsnails were found at a Lake Tahoe boat-inspection station on May 25 in the live-well of a boat from the San Francisco Bay Area. Water samples from the lake haven't turned up mudsnails, according to the U.S. Fish and Wildlife Service.
