For the first time, a small, invasive aquatic snail has been discovered at the Lake Sonoma Fish Hatchery. The New Zealand mudsnails were recently found during routine monitoring of an intake pipe that draws water from Lake Sonoma. The U.S. Army Corps of Engineers uses the water pipe for its coho salmon and steelhead trout broodstock program. The discovery is causing concern about releasing the young fish into the Russian River Watershed later this year. The snails have been found in other waterways state and nationwide.
