Superior National Forest: Portions of the Forest have reopened for public use. As of August 13, more than 1,600 of the roughly 2,000 BWCAW campsites are available (approximately 73%). Visit the Forest’s Alerts webpage for maps and information on recreation, BWCAW, and fire restrictions.
The Forest is managing the Little Knife Fire. It remains at 4,815 acres, 90% contained and with no threats to the perimeter. Minimal fire activity. Additional updates on this fire will occur if conditions change.
July Lightning Fires: 75,970 total acres (67,075 in U.S., 8,895 in Canada); 619 personnel.
•Camp Fire: 4,357 acres; 97% contained; 5 miles north of Winton. The earlier spot fire east of the main fire in an area due east of Muskeg Creek has been mopped up and will be put into patrol status by air. The Cloquet Line has a few days of chipping work left on it and the rest of the fire area is being assessed for suppression repair needs.
•Sioux Fire: 6,832 acres; 53% contained; north of the Echo Trail and east of Jeanette Campground. Firefighters are cold trailing and mopping up any hot spots on the east flank and west side of Ramshead Lake. Repair work will begin on dozer line on the south end of the fire. An Unmanned Aircraft System (UAS/drone) will assist on the west side of the fire to identify any hot spots. Crews will utilize aircraft and watercrafts for logistical support to back haul equipment from the area.
•Bear Trap Fire: 39,267 total acres (30,872 acres in the U.S.); 51% contained; 20 miles north of Ely. Firefighters used a drone to assist in locating any remaining hot spots along the south and southeast perimeter of the fire. They will also be scouting the entire 12 miles of the Angleworm Lake Trail for additional repair needs. Mop-up and cold trailing will occur from Wagosh to Nikki Lake. Crews worked to improve portage access from Angleworm trailhead to Angleworm Lake and between Angleworm Lake and Home Lake yesterday.
•Thumb Fire: The Thumb Fire burned into the Wolfpack Fire and the combined fires are now known as the Thumb Fire. 25,514 total acres (25,014 acres in the U.S.); 46% contained; 6 miles south of Gakijiwanong Anishnaabe Nation, Canada. Mop-up and cold trailing will continue today along the fire perimeter, as well as in the northwest corner. A UAS will assist in identifying to check for any areas that are not currently contained. Backhauling will continue for any unused equipment. Crews rechecked sections of line on Coleman Island and were able to confirm containment.
•Echo Trail Road: Work continues to develop a shaded fuel break along the Echo Trail. Two miles of the road remain to be completed and logged. This shaded fuel break is important to help reduce the intensity and slow the spread of any future fire activity. A thin canopy of large, mature trees will remain. This will retain shade, which will help suppress the rapid regrowth of brush, and increase defensible space. Masticators, large and small chippers are being utilized for the operation, as well as road graders to improve the road in the southeast and western sections of Echo Trail in the fire area. Expect substantial delays if you travel along the Echo Trail.
Weather and Fire Behavior: A high-pressure system will arrive on Wednesday leading to similar weather conditions to what was observed on Tuesday. Breezy northwesterly winds will be the main concern with gusts approaching 20mph. Changes are on the horizon as our next weather system moves in on Thursday with chances for rain showers and isolated thunderstorms expected through much of the day. Another chance of showers and isolated storms will be present on Friday before we finally clear out for the weekend. Recent rainfall has significantly reduced fire behavior. Fire spread should remain limited today, along with the probability of new fire starts.
Temporary Flight Restrictions: Temporary flight restrictions are in place over the fire area. A permanent flight restriction covers the Boundary Waters Canoe Area Wilderness. Visit the Federal Aviation Administration website for more information: https://tfr.faa.gov/tfr3/?page=map
