Yellowstone fisheries are already threatened by damaging invasive species. The whirling disease parasite and introduced lake trout have resulted in a loss of cutthroat trout from Yellowstone Lake. New Zealand mud snails occur in many park streams, impact aquatic insect communities, and ultimately affect the angling experience. Our Aquatic Nuisance Species (ANS) brochure (423 KB pdf) includes a map showing locations of whirling disease and New Zealand mudsnails in the park, which can be easily transported on waders or other fishing gear. WARNING! ANS (Aquatic Nuisance Species) HOTZONES include popular fishing locations on the following streams:

Be aware that you may easily spread harmful ANS if you do not clean your gear after fishing in these areas! Help prevent further spread of ANS by thoroughly cleaning mud, plants, and debris from your fishing equipment and footwear BEFORE leaving your angling site. Drain boat livewells and clean fish ONLY near the same body of water in which they were caught.
Preservation of aquatic resources and quality angling in the future depends on you! Please, before coming to Yellowstone:
CLEAN YOUR BOAT!
