Chinese mystery snail (Cipangopaludina chinensis), a non-native species introduced to the U.S. via San Francisco in the late 1800’s. It has since spread into at least 37 U.S. states and 4 Canadian provinces and was first documented in New Jersey in 1926. According to Jay, the species has been “implicated in vegetation decline, competition with native species, and are hosts for certain parasites. Current populations are spread through the aquarium trade or on ornamental aquatic plants.”

Some lakes have a lot of them, and most don't have any.
I guess it depends on a combination of factors such as a high level of organic mater and alkaline water.
