Foss Lake Fire mapOn Saturday the U.S. Forest Service reported that better mapping showed that the Foss Lake Fire, that escaped from a prescribed fire in northeast Minnesota, had not burned 1,000 acres as previously reported, but only 440 acres. On Sunday morning their update said it was 1,008 acres, and included this information:

There was little growth on the fire yesterday. Accurate mapping data from handheld and aircraft GPS units resulted in the large increase in acreage.

The U.S. Forest Service has provided more details about the escaped prescribed fire 15 miles west of Ely, Minnesota. Better mapping shows that it has burned approximately 440 acres rather than 1,000 from the earlier estimate.

From the Superior National Forest at about 10 p.m. CDT on Friday:

The fire is burning north within the Boundary Waters Canoe Area Wilderness (BWCAW).

Crews made good progress today, directly attacking the fire on its north, east, and west sides. Aircraft dropped fire retardant along the east side of the fire and water on the west side.

Background: The Foss Lake Fire began on May 19 as a prescribed fire to reduce surface and ladder fuels, to enhance wildlife habitat, and to encourage jack pine regeneration. Shortly after ignition, an unpredicted change in weather conditions brought higher winds, warmer temperatures, and lower relative humidity. A spot fire north of the control line escaped containment and the wind-driven fire spread to the north. Aircraft that were on standby responded quickly and, with the work of ground crews, were able to slow the fire’s eastward spread with water and retardant drops, protecting the west and north sides of Burntside Lake. The fire spread north to Crab Lake in the BWCAW. There was no fire growth to the south.

Message: There is no threat to the towns of Ely, Winton, Tower, or Soudan. No structures are threatened. Good fuel-reduction work completed over the last two years on Burntside Lake increases firefighters’ ability to manage the eastern edge.

Resources: 80 personnel and 8 aircraft. MNICS Type II Team under Incident Commander Brian Pisarek arrived today and will take command of the fire Saturday morning. The Lake Vermilion Fire Brigade and the Morse/Fall Lake Fire Department both have fire boats on Burntside Lake are conducting structure-protection assessments.

A prescribed fire on the Superior National Forest escaped control Thursday 15 miles west of Ely, Minnesota. The intent was to burn 78 acres north of Tamarack and Foss Lakes north of the 404 Road. By late afternoon the fire had been assigned a name, Foss Lake, and was creating a large convection column of smoke topped by a pyrocumulus cloud, an indication of fire intensity.

Thursday night the Forest Service was not able to provide a size estimate due to the smoke restricting visibility.

The fire was fought yesterday by firefighters on the ground assisted by eight aircraft.

Thursday before it escaped there were 10 hand crews prepositioned in Minnesota that were not assigned to fires. Presumably many of those are now working on the Foss Lake Fire.

Yesterday’s afternoon weather conditions near the fire were 74 degrees, 6 mph wind gusting to 19 mph, and 16 percent relative humidity. The forecast for Friday: 74 degrees, south wind at 6 mph, 51 percent cloud cover, and 22 percent relative humidity. There is no rain expected until Monday.

We will update this article as the situation develops.
