Chub Fire Grows to Nearly 319 Acres Near Crane Lake While Creek Fire Remains Small: Smoke and Air Quality Concerns Continue for Northern Minnesota
Published: July 16, 2026
Firefighters continue responding to two active wildfires in St. Louis County, Minnesota, as dry fuels and ongoing wildfire activity across northeastern Minnesota contribute to smoky skies and deteriorating air quality.
The Chub Fire, burning north of Chub Lake and southwest of Crane Lake near Orr, has grown to 318.8 acres. Nearby, the Creek Fire, located about one mile southeast of Ninemile Spur A and Ninemile Spur AB and approximately 1.5 miles northwest of Chub Lake, remains much smaller at 3.3 acres.
Chub Fire Update
The Chub Fire is burning in a heavily forested portion of northern St. Louis County within an area already experiencing elevated wildfire activity this summer. Fire crews continue working to limit fire growth while monitoring weather conditions, fuel moisture, and changing wind patterns.
Although the fire remains relatively small compared to some of Minnesota’s largest ongoing incidents, it is part of a broader wildfire outbreak affecting northeastern Minnesota and the Boundary Waters region.
Creek Fire Remains Small
The nearby Creek Fire has been mapped at 3.3 acres and is receiving suppression efforts to prevent additional spread. Quick initial response has helped keep the incident limited, though firefighters continue monitoring the area for changing conditions.
Because the two fires are located close together, fire managers are watching for any shifts in weather that could increase fire behavior.
What This Means for Surrounding Communities
Residents in and around:
- Crane Lake
- Orr
- Buyck
- Vermilion Lake communities
- Echo Trail recreation areas
should remain prepared for changing wildfire conditions.
While immediate structural impacts may remain limited, communities could experience:
- Reduced visibility from wildfire smoke
- Temporary road or recreation area closures
- Increased firefighting aircraft activity
- Possible changes to outdoor recreation access
- Continued smoke impacts during overnight and morning hours
Visitors heading into northern Minnesota forests should also check for any updated closures before traveling.
Air Quality Becoming a Major Concern
Even when flames are not directly threatening communities, wildfire smoke can create widespread health impacts.
Air quality across northeastern Minnesota has worsened as smoke from multiple Minnesota and Canadian wildfires combines over the region. State officials have issued air quality alerts for portions of northern Minnesota, with smoke capable of affecting locations well beyond the active fire perimeters.
People most at risk include:
- Children
- Older adults
- Pregnant women
- Individuals with asthma or COPD
- Anyone with heart or lung disease
How to Stay Safe During Smoky Conditions
If smoke becomes noticeable in your community:
- Limit prolonged outdoor activity.
- Keep windows and doors closed when air quality is poor.
- Run air conditioning on recirculate if available.
- Consider using a HEPA air purifier indoors.
- Wear a properly fitted N95 respirator if extended outdoor exposure is unavoidable.
- Monitor local air quality reports before exercising outdoors.
Fire Weather Remains Critical
Northern Minnesota continues to experience conditions favorable for wildfire activity, including dry vegetation and periodic gusty winds. Although some fires have shown reduced behavior during calmer periods, weather changes can quickly increase fire spread potential.
Officials continue encouraging residents to avoid activities that could spark new fires while firefighters remain engaged across numerous incidents throughout the region.
Looking Ahead
The Chub Fire and Creek Fire remain active incidents requiring continued monitoring. While firefighters work to contain both fires, smoke is expected to remain one of the biggest concerns for nearby communities, especially as regional wildfire activity continues across northeastern Minnesota.
Residents are encouraged to stay informed by monitoring local emergency management updates, wildfire notifications, and daily air quality forecasts before planning outdoor activities.
