Delta Lake and "West Zone" Fires Fact Sheet July 25, 2021

Delta Lake Fire Wildfire
Announcements – 7/25/2021

 SUMMARY: The West Zone of the Superior National Forest, consisting of the Laurentian, Kawishiwi and LaCroix Districts, continues to have steady fire activity due to ongoing moderate to severe drought conditions.  The Type 2 Eastern Area Incident Management Team is now in transition with a Type 3 Minnesota Incident Command System Team.  The mission will be to continue to support the Forest with suppression efforts on the West Zone as delegated and all planning efforts associated with three Canadian fires threatening the U.S. border adjacent to the BWCAW. Local Forest fire resources continue to respond to and suppress any new fire starts.  

DELTA LAKE FIRE: Fire was reported on July 7th on state and National Forest System lands, adjacent to the Boundary Waters Canoe Area Wilderness (BWCAW), in dense blowdown. The 62-acre fire is 85% contained. Containment lines held with the strong winds from the previous day. The recent rain moderated any interior pockets still smoldering. All roads leading to the fire after the storms are clear of any debris and downed trees. Crews continue to fine-tune their structure protection plans and haul sprinkler, hose and pumps out of areas that are secured with contingency lines. A closure area in the BWCAW near the Delta Lake Fire was lifted on July 23rd.

OTHER RECENT FIRE STARTS:  Several fire starts have been reported on the Forest over the last week. The Sundial South Fire is .1-acre and the Rock Island Fire is 1.5-acres—both are in patrol and monitor status. The Phantom Creek Fire is 1-acre and the Bear Creek Fire near Lake Vermilion, approximately 7-acres, are both actively being suppressed and monitored.  Helicopters, with water dropping capability, have been working these fires over the last week supporting the personnel on the ground.  The fires will continue to be monitored for any additional growth or heat. 

CANADA FIRES: There are several wildfires burning in Quetico Provincial Park in Canada, directly across the international border from the BWCAW in the Superior National Forest. Three fires have the potential to spread across the border into the areas of Crooked and Iron Lake.  An air assessment flight was conducted; personnel reported some heat on the southern perimeter, but mostly creeping with very little movement thanks to the recent rain. Entering a dry pattern; expecting more growth over the coming days. Crews continue working near Curtain Falls, concentrating on developing contingency lines, prep-work and identifying critical resource needs.  Structure protection planning and mitigation efforts are finishing up. Public safety division will continue making sweeps within the closure area and talking with the public. 

WEATHER: Critical fire weather today.  Entering a dry pattern with high temperatures, low humidity and gusty, erratic winds.  Expect to see sunny skies with a high near 82 degrees and minimum humidity of 27%.  West winds are forecasted to be light 3-5 mph in the morning, but increasing in the afternoon with gusts up to 25 mph. 


There is one area closure in place adjacent to the Canadian border in BWCAW. For details, visit the Superior National Forest webpage at    The closure will be in place until fires in the region no longer pose a risk to public safety.
