Mudsnails, Pondweed invading

The Wyoming Game and Fish Department has verified the presence of two aquatic invasive species in Flaming Gorge Reservoir.  Those are curly pondweed and New Zealand mudsnails.
Both species of AIS have been found in Wyoming before, however this is the first time New Zealand mudsnails have been documented above the Flaming Gorge dam. Game and Fish AIS personnel were able to confirm the presence following tips from the public.
In mid-June, an angler reported a sighting of curly pondweed at the reservoir south of the Anvil Draw boat launch. Subsequently the same angler, while fishing from a boat, found another clump of curly pondweed floating in the south end of Big Bend.
Upon investigation, more curly pondweed was found north of Bringer’s Ferry boat launch, as well as mudsnails.
