D. Permitting and Aquatic Invasive Species (AIS)
  1. All watercraft, trailers, tow vehicles, and other articles immersed in park waters must have a Yellowstone boat permit and a Yellowstone Aquatic Invasive Species (AIS) inspection before launching in the park. During boating season, permits and inspections are available seven days a week between 8 a.m. and 4:30 p.m. at locations throughout the park. Current list of AIS inspection locations can be found at: https://www.nps.gov/yell/planyourvisit/boating.htm.
    a. Any watercraft and associated equipment must be thoroughly inspected prior to entering any waters within the park. Prior to launching, all watercraft (and associated equipment) must be re-inspected each time they re-enter the park.
    b. A 30-day dry time is required for all sailboats and certain motorized boats (inboard, inboard/outboard, or inboard jet drives). Without a valid AIS inspection receipt and intact seal demonstrating a 30-day dry time, this watercraft will be denied launch. Additional information may be found at: https://www.nps.gov/yell/planyourvisit/boating.htm.
    c. CUA operators must arrive at AIS inspections stations with all equipment requiring inspection clean, maintained, and prepared for inspection. Equipment that requires any type of cleaning will be turned away. If a watercraft does not pass the Yellowstone AIS inspection, it is not allowed to enter park waters.
    d. To prevent the introduction of AIS, the holder must ensure all equipment is cleaned and dried before entering or changing Yellowstone waters.
    e. All park waters should be assumed to contain undetected AIS.
    f. Watercraft that are dirty, have standing water, or that possess plants or animals may be decontaminated prior to launch or could be denied launch.
    g. The following watercraft and equipment are banned from entering the waters of Yellowstone National Park:
    • Watercraft with evidence of dead or live quagga or zebra mussels.
    • Watercraft previously fouled with mussels, regardless of cleaning or dry time.
    • Watercraft equipped with a ballast tank or similar areas that cannot be visually inspected.
  2. This permit allows guided fishing from the watercraft. All clients and guides 16 years and older who are fishing must have a Yellowstone National Park (YNP) fishing permit. All clients and guides fishing must obey park fishing regulations located at: https://www.nps.gov/yell/planyourvisit/fishing.htm.
    a. Fish that are kept must be cleaned at a cleaning station if possible. Otherwise, all entrails should have the air bladders punctured and then be thrown into the deepest water possible where they were caught. It is prohibited to bury, burn, or leave fish entrails on shore.
    b. If providing fishing services, guides must carry a copy of digital or paper NPS Fishing Regulations for the current year.
E. Staffing and Employment
  1. Guides must complete National Association of State Boating Laws Administrators (NASBLA) approved boater safety course or hold vessel endorsement issued by a state, see https://www.boat-ed.com/ and https://www.boaterexam.com
  2. One guide on each trip must be certified Wilderness First Aid, Wilderness First Responder, Emergency Medical Technician, or higher-level certification. All guides must have current CPR and first aid certification.
F. Operational Requirements
  1. All guides and trip participants must adhere to all Yellowstone Boating regulations. Regulations may be found at: https://www.nps.gov/yell/planyourvisit/upload/Yellowstone-Boat-Safety-and-Regulations-Booklet.pdf
  2. While on Yellowstone Lake or Lewis Lake, the holder or guide shall remain with their clients for the duration of the trip.
  3. One guide on each trip must have previous boating experience in motorized boating and previous experience on the lakes where they are guiding.
  4. All accidental swimmers must be reported to CUA office within 48 hours, detailing what happened and company's response.
  5. Watercraft must not drift within 25 yards (approximately 23 meters) of shoreline thermal features and submerged thermal features and are not allowed to land within thermal areas or within 25 yards (approximately 23 meters) of thermal features. Holders and guides are responsible for knowing the location of submerged thermal features or vacating an area where a submerged thermal feature is discovered.
  6. Class I (16' to 26') and Class II (26' < 40') motorized boats shall proceed no closer than 1/4 mile from the shoreline of the South and Southeast arms of Yellowstone Lake except to debark or embark passengers, or while moored when passengers are ashore (36 CFR 7.13(9)(i)).
  7. Please be aware that cellular phone coverage does not cover all locations on the lakes. All Federal Communications Commission (FCC) licensing requirements need to be followed. Information on FCC licensing requirements can be found at: https://www.fcc.gov/obtaining-license.
  8. Watercraft equipped with sealed internal water ballast tanks are prohibited in the park due to increased risk of introducing AIS in Yellowstone waters. This type of watercraft has tanks that can be filled with water to produce specific wakes for waterskiing and wakeboarding (neither activity is allowed in the park).
  9. Overnight backcountry use is not authorized under this CUA. Any business offering backcountry camping trips accessible by watercraft (in which the holder is the primary vessel operator) must obtain an Overnight Backcountry CUA in addition to the Motorized Boating CUA.
