River Use Regulations

For the river environment’s protection and your safety, observe these regulations on both sides of the river and on private land along the Rio Grande Wild and Scenic River.

  1. Any river user must obtain a National Park Service backcountry-use permit before watercraft is placed or operated on the Rio Grande within Big Bend National Park and for overnight trips on the Rio Grande Wild and Scenic River downstream from the park. Day-use inner tubes are exempt.

  2. Each person shall have a wearable U.S. Coast Guard approved personal flotation device (PFD) which is properly fitted, in serviceable condition, and immediately accessible while on the river. Type I, III, or V PFD's are required for Santa Elena, Mariscal, and the Lower Canyons. PFDs must be worn in Class II or greater difficulty whitewater. PFDs are recommended but are not required for people floating the river on inner tubes. Each group shall carry one extra type I, III or V PFD.

  3. Each vessel shall carry an extra paddle or oar; kayaks shall have an extra paddle per party.

  4. Each group using inflatable vessels, except air mattresses or inner tubes traveling with a support vessel through the major canyons, will carry an operable pump and a patch kit capable of making major repairs.

  5. No vessels shall carry more than a safe load (in persons or total weight) considering type of craft, intended use area, and water and weather conditions.

  6. Inner tubes are not allowed in Mariscal Canyon, Santa Elena Canyon, and Lower Canyons.

  7. Starts and Group Size — A start is defined as a launch or an entry from another river segment. River segments are defined as follows:

    Lajitas (West Boundary) to Santa Elena Canyon take-out
    Santa Elena Canyon take-out to Cottonwood Campground
    Cottonwood Campground to Reed Camp
    Reed Camp to Talley
    Talley to Solis
    Solis to La Clocha
    La Clocha to Boquillas Canyon Entrance
    Boquillas Canyon Entrance to La Linda (East Boundary)
    La Linda to Foster Ranch

    On the Rio Grande Wild and Scenic River downstream from Big Bend National Park, the group size limit is 20 people for private groups. Commercial operators may start a maximum of 20 persons per day, not including guides.

    Within Big Bend National Park the group size limit is 30 people for private groups, except for the following segments: Talley to Solis, and Boquillas Canyon Entrance to La Linda (East Boundary), where the limit is 20 people.

    No more than three parties per day may be started by any group, organization, or commercial operator. River parties must start at least 2 hours apart.

    Individual river groups must travel, camp, and eat lunch separate from other groups.

  8. Respect property rights and do not trespass on posted land.

  9. Use or discharge of firearms is prohibited. All wildlife is protected by federal law. Possession of other weapons, traps or explosives is prohibited.

  10. Pets are not permitted on the river or in any other part of the backcountry.

  11. The destruction, injury, defacement, removal, or disturbance of any natural or cultural feature is prohibited.

  12. Overnight trips must have a firepan with sides at least 2 inches high. Fires must be contained in firepans. Burn only charcoal or down and dead wood. Carry out all floatable remnants of the fire; non-floatable debris should be carried out, or may be disposed of in the main current of the river. Reduce impacts by using only charcoal or self-contained stoves.

  13. Deposit refuse, including cigarette butts and toilet paper, only in facilities designed for that purpose at take-outs or subsequent points. Strain liquids, including dishwater, and deposit them in the river. Carry out strained materials.

  14. All solid human waste must be carried out, with the following exception: kayak-only or single-canoe trips. Carryout is encouraged, but not required, between the Santa Elena Takeout and Talley, and between Solis and the Boquillas Canyon entrance.

  15. Jug fishing is not permitted within Big Bend National Park. Trot lines may not span the river.

  16. Camping is not permitted in the following areas: from the upstream end of the Santa Elena Canyon Nature Trail to 3/4 mile downstream from Castolon; within 1/2 mile of the San Vicente Crossing; and from La Clocha to the Boquillas Canyon Trail terminus.

  17. Consumption of alcoholic beverages in the Langford Hot Springs area is prohibited.

  18. Report any accident with an injury or property damage of $100 or more to the NPS.

  19. Motorized watercraft used within the park is limited to conventional boats with up to 60 horsepower inboard or outboard motors. Jet skis are not allowed in the park. Motorized watercraft will be prohibited on the following sections of the Rio Grande River: Santa Elena Canyon, from the western park boundary to the Santa Elena Canyon take-out, Boquillas Canyon, from the entrance of Boquillas Canyon to the eastern boundary of the park. Motorized watercraft will be prohibited on the following section of the Rio Grande River except for the month of October: Mariscal Canyon, from Talley to Solis.

 

Recommendations
The NPS recommends the following for your safety and the protection of the river environment:

  • When the river exceeds 2,000 cubic feet per second (cfs) on the Johnson’s Ranch gauge, permits should be limited to the following boats in Santa Elena, Mariscal, and Lower Canyons: inflatable rafts with a minimum of three air chambers (excluding thwarts) and minimum dimensions of 6 by 12 feet; rigid, decked canoes and kayaks that exclude water when used with a spray skirt; open canoes 50 percent filled with flotation; dories; and sport kayaks. This suggestion also applies when an upstream rise causes any such section to exceed 2,000 cfs.
  • Wear PFDs at all times; carry one extra per trip. Type II PFDs (horsecollar) are not allowed in Santa Elena, Mariscal, or the Lower Canyons and not recommended in the other sections.
  • Each river party should carry a suitable amount of survival gear, including a first aid kit, extra water, sun protection, rain gear, a throwline, and an extra rope at least 50 feet long and 3/8 inch in diameter.
  • The safe capacity for inflatable craft should be considered 1/2 the manufacturer’s rated load. If no such rating can be found, the mid-line of the boat should be at least 2 inches above the water line. The safe capacity for canoes is no more than 2 persons and 100 pounds of gear in Class III or greater whitewater.
  • All major rapids should be scouted. Consider portaging.
  • Springs may be contaminated. Treat water from a natural source before drinking.
  • Because sudden river rises occur, camp well above the high water mark and out of any side canyon or arroyo. Secure boats with ropes and tie each craft separately.
  • Theft of property from unoccupied vehicles and campsites is a problem in remote areas. Leave no valuables in vehicles.
  • In the event of an emergency, an “X” marked on the ground by any means visible from the air signifies that help is needed. Carry two 3-by-10-foot strips of international orange colored material and a signal mirror. Flights over the river are limited; do not count on being spotted quickly.
