 Fall Open Burning Season: October 1- November 30

Burn permits are NOT required during open burning seasons. Burning is not allowed December, January, and February due to air quality concerns.



Fall is the perfect time to clean up and burn natural yard debris around your home and property. Before lighting your fire, remember that most of the human-caused wildfires in Flathead and Lake Counties are started by escaped debris burns. Here are a few tips:
  • Air Quality Compliance is required. Check the ventilation & burning forecast:
  • Check the weather forecast and postpone burning if gusty or high winds are predicted.
  • Create a control line by scraping the area around your pile to mineral soil.
  • Have enough water, hand tools, & help on site to extinguish your fire if necessary.
  • Remember, you may be held financially responsible for the cost of suppressing escaped fires.

You can improve the defensible space around your home and prepare for next fire season by clearing brush & trimming lower limbs of trees. A few guidelines include:

  • Maintain a 3-5 foot non-combustible perimeter be removing any flammable vegetation that is in direct contact with your home.
  • Prune tree branches up 6 to 10 feet from the ground to remove "ladder fuels," or those fuels that allow a fire to climb from the ground into the tree canopy.
  • Remove any trees or prune any branches that are overhanging or touching your home.
  • Create 10 to 15 foot spacing between crowns (the widest part) of trees to reduce the chance of fire moving from tree to tree.


Debris burning is not allowed within city limits of Kalispell, Whitefish, and Columbia Falls.

Only two types of debris burning are allowed in Montana:

1) Agricultural debris - This debris is created from farming, ranching, and gardening.

If possible, plow or dig a fire control line around the area to be burned and divide large fields into smaller plots to be burned one at a time. If you do not want to burn, your field or garden may benefit if you simply plow the dried plants and leaves under.

2) Wildland debris - This debris is created in two ways.

A. Natural accumulations of needles, grasses, leaves, shrubs, limbs, and trees. 
B. Unnatural accumulations of fuel resulting from management activities such as land clearing or timber harvesting.

Materials that are prohibited to burn include business waste, treated or painted wood or lumber, tar paper, tires, insulated wire, any salvage, oil products, styrofoam or plastics, food wastes, animal parts or waste, hazardous waste, noxious waste, and any man-made material. Trade Waste permits may be issued for wood or wood by-product trade wastes generated by any business, industry trade, or demolition project. Trade waste permits may be obtained by calling your local city-county health department. For more information, contact the appropriate agency:

In Flathead County call the Flathead City-County Health Department at 751-8130 or Click Here and scroll down.

In Lake County call the CSKT Division of Fire at 676-2550 or the MT DEQ at 444-4267

Escaped debris fires can threaten valuable resources, as well as lives and property. Follow the information provided under "Tips for burning" to reduce the risk of an escaped debris fire.

Remember, you are responsible for any and all suppression costs if your fire escapes your control! (State Statute 50-63-103 MCA)

Tips for Burning


  • Keep piles clean and free of dirt. Use brush blades on dozers when piling slash. When possible, use an excavator to pile.
  • Build small piles so the fire will be hot, yet manageable. Wet or dirt-covered materials will cause fires to smolder and emit more smoke.
  • Build piles in openings away from bodies of water, structures, or overhead branches and wires.
  • Piles may be covered with plastic or waterproof paper to keep them dry. This will allow them to be burned when nearby fuels are too wet to burn and control is no longer a problem or concern. Remember to remove the plastic before igniting the piles.
  • Scrape a control line by removing any debris and any other burnable materials several feet around the piles to be burned. The result should be bare soil around each pile. You may also use a hose to wet down the area around the pile.
  • Keep plenty of water, personnel, tools, and equipment on hand in case of unexpected changes in fire behavior.
  • Light the fire only when you have an update on favorable weather and safe burning conditions. (e.g. winds calm, weather cool)
  • When possible, continue to re-pile debris as material is consumed. This will allow the fire tostay hot and to burn out as quickly as possible.
  • Stay with your fire. Be prepared to put your fire out if it becomes difficult to manage.

If you intend to burn, have in place:

  • A current weather forecast for your local area (NOAA, Weather Underground , The Weather Channel)
  • Water source (a charged hose, buckets, pond or lake...)
  • Fire tools (long-handled shovel, rake, hoe...) or equipment depending on the size of your burn
  • Enough help to repond in the event that fire behavior increases.

Do not burn when high or erratic winds are forecast or dry conditions prevail. Do not attempt to bury any burning material as fire can and will burn underground, sometimes for several months!


Burn barrels should not be used to burn garbage. If burn barrels are used, please burn only agricultural or wildland debris.


  • Making a compost pile out of small organic materials
  • Using thinning and logging debris for firewood
  • Tilling vegetative waste materials into the soil
  • Hauling debris to a landfill
  • Chipping logging debris and slash
  • Lopping and scattering logging debris
  • Machine crushing or trampling the logging debris.

If no restrictions are in place, a permit is not needed for campfires measuring less than 48 inches in diameter.
  • Recreational campfires are allowed year-round when no restrictions are in place.
  • A campfire must be constructed in an area free of flammable materials; check for overhanging branches.
  • Do not allow your campfire to spread beyond the established ring, pit, grate or container.
  • A shovel, or other fire tools, and a sufficient amount of water to extinguish the fire must be on site.
  • Never leave a campfire unattended, and make sure it is DEAD OUT before vacating the site.

During the summer, as wild fire danger increases, special fire restrictions may be established by an authority having jurisdiction. Restrictions prohibit building, maintaining, attending or using a fire or campfire on public or private property.
