Derby Fire: BLM issues land closure in Garfield and Eagle Counties for firefighting activities

Bureau of Land Management

GRAND JUNCTION, Colo. — Today, the Bureau of Land Management issued an order closing BLM-managed public lands in Garfield and Eagle Counties because of the Derby Fire. BLM issued the emergency closure to keep the public and firefighters safe while fire activity is in the area. The order is effective immediately and the closure will remain until fire managers declare the Derby Fire controlled or BLM rescinds the order.

This closure affects BLM lands north and west of the town of Gypsum, Colorado, that are north of Coffee Pot Road; west of the Colorado River; east of the White River National Forest boundary; and south of Derby Creek.

Please refer to the map below and closure order (on the BLM website) for detailed information on the lands that are closed.

The temporary closing of the lands is to reduce exposure to hazardous situations due to the recent, rapid rates of spread and fire behavior of the Derby Fire. The public is to remain clear of these closed lands. Please use caution and watch for firefighters when traveling in the area.

Violations of this emergency order may lead to prosecution, with fines and possible imprisonment.

We appreciate your understanding as we prioritize safety and resource integrity during this critical time. For more information about the land closure, please call the Colorado River Valley Field Office front desk at 970-876-9000. For more information about the Derby Fire, please call the fire information line at 970-355-3283.

Routt National Forest in Stage 2 fire restrictions

Garfield County Sheriff’s Office

August 15, 2025, 6:26 p.m. – Important fire safety update:

The below press release from the U.S. Forest Service – Routt National Forest contains important information for anyone recreating in our area. Parts of Garfield County fall within the Routt National Forest, so please take a moment to read through the details before you head out.

For a list of surrounding areas in Stage 2 Fire Restrictions and what it means visit here: https://www.garfieldcountyco.gov/emerg…/fire-restrictions/

Let’s all do our part to protect our beautiful lands and keep our community safe.

Map of fire restrictions in the Routt-Medicine Bow Wilderness.

United States Forest Service

Sections of Routt National Forest are in Garfield County

Severe conditions put Routt National Forest in Stage 2 fire restrictions

Campfires are not allowed under these restrictions.

(LARAMIE, Wyo.) August 15, 2025 – Effective immediately, Stage 2 fire restrictions are in place for the Routt National Forest in northwest Colorado.

This includes National Forest System lands located in Garfield, Grand, Jackson, Moffat, Rio Blanco, and Routt counties.

The U.S. Department of Agriculture, Forest Service has communicated with all affected counties, state agencies, and neighboring federal land managers on the timing of the restrictions.

All criteria have been met for the Forest to move into Stage 2 restrictions and the USDA Forest Service is aligned with surrounding land managers regarding this action. Tightened restrictions are necessary due to extreme, dry fuel conditions that are receptive to fire, persistent fire weather patterns, and the danger of human-caused wildfires. Recent weather conditions have resulted in an elevated potential for wildfires. Fire restrictions will help protect public health and safety, as well as natural resources.

The Routt National Forest was last in Stage 2 restrictions in 2020 and has been in Stage 1 restrictions since July 10 of this year.

The following prohibitions are in effect until further notice:

  • Igniting, building, maintaining, attending, or using a fire, campfire, charcoal barbecue, or grill, except if using a device solely fueled by liquid or gas that can be turned on and off in an area barren or cleared of all flammable materials within three feet of the device.
  • Smoking, except in an enclosed vehicle or building.
  • Welding or operating an acetylene or other torch with open flame.
  • Using an explosive.
    • This includes but is not limited to fuses, blasting caps, fireworks, rockets, exploding targets, tracers, and incendiary ammunition.
  • Possessing or using a motor vehicle off NFS roads, except when parking in an area devoid of vegetation within 10 feet of the motor vehicle.

Personal, portable wood or charcoal burning fire pits/rings, often made of stainless steel, are not allowed under these restrictions. Only gas-fueled devices with an on/off switch may be used.

Always important for fire prevention and enforceable year-round is the following prohibition regarding spark arrester use:

  • Operating or using any internal or external combustion engine without a spark arresting device that is properly installed, maintained, and in effective working order in accordance with USDA Forest Service Standard 5100-1.
    • For chainsaw use, it is recommended the operator have a chemical pressurized fire extinguisher (with a minimum 8 oz. capacity and rating of 2A) and a round point shovel with an overall length of at least 35 inches readily available for use.

Violation of the Stage 2 Fire Prohibitions is punishable as a Class B misdemeanor by a fine of not more than $5,000 for individuals and $10,000 for organizations, or by imprisonment for not more than six months, or both. Anyone negligently or willfully starting a wildland fire could also be held responsible for the costs of that fire.

Forest staff will continue to monitor conditions to assess the need for further action, including additional restrictions if weather remains hot and dry and lessening restrictions if a wetter and cooler weather pattern develops.

To report a wildland fire, please call the Northern Colorado Interagency Dispatch Center, (970) 295-6800.

Call your local office for site-specific information.
