Improved mapping reduces acreage on Twelvemile Lake and Sand Lake fires

Improved mapping has led to a reduction in reported acreage on both fires. The Twelvemile Lake Fire (#220) is now estimated at 18,028 acres—a reduction of 717 acres. The Sand Lake Fire is now 4,821 acres, down 58 acres from yesterday.

Firefighters continued work at Healy Lake, scouting an alternate helispot in case rising water impacts the existing one. Equipment checks continued, and all systems remain operational.

Crews responded to a report of possible smoke near Healy Creek—an area near values at risk—but after flying the area, no fire activity was found. A secondary aerial reconnaissance revealed only light heat pockets along the west side of the Twelvemile Lake Fire. Overall conditions remain stable.

At Lake George, firefighters made final adjustments to sprinklers and pumps, confirming all systems are functioning. The Sand Lake camp is now fully staffed, with all personnel and supplies inserted today. Teams are ready to respond if fire behavior increases.
