Update Sept 13
Incident: Jack Creek Fire Wildfire
Fire footprint expands in the Eightmile and Stuart Lake drainages
Based on a recon flight yesterday, new fire acreage is estimated at 3,724. Observed fire activity on Tuesday consisted of smoldering, creeping and isolated single tree torching; with most of the new activity occurring Monday afternoon, when the smoke column was the most visible. The majority of the perimeter growth occurred in the Eightmile, and Stuart Lake basins, increasing the perimeter by approximately 700 acres near Eightmile Lake, and 200 acres near Stuart Lake. Monday’s fire activity burned heavy pockets of timber within Eightmile, and Stuart Lake basins. Portions of the new perimeter growth can be characterized as high intensity. The fire is expected to continue to grow in all directions however; predictive services forecast cooler seasonal weather trends, which should temper new perimeter growth.
Yesterday firefighters implemented additional point protection measures on recreational features around Colchuck Lake. This included wrapping vault toilets, Wallowa toilets, foot bridges, and a helipad in fire protective material. Firefighters are prepared to implement additional actions to protect Values at Risk when necessary. Suppression actions will be taken where lightning-caused fires pose serious threats to life and/or property within wilderness or to life, property or natural resources outside of wilderness.
The Jack Creek Fire is predominantly a mixed severity burn, with areas of high and low burn intensity.
The fire has burned understory and pockets of tree stands creating openings on the landscape promoting diversity. The mosaic pattern is beneficial for the landscape, in this fire-adapted ecosystem. The current management strategy of monitoring while providing point protection, allows the Jack Creek Fire to play its natural ecological role of enhancing forest health, while maintaining wilderness values and helping prevent uncharacteristic fires in the future. Public and firefighter safety are also a priority.
Air quality is expected to improve in the Leavenworth and surrounding areas. The Forest Service works closely with other federal and state partners to predict and mitigate smoke impacts on individuals and communities during wildfires, visit wasmoke.blogspot.com for air quality information. Leavenworth and Lake Wenatchee area businesses are fully open and operational.
Closures: All closures associated with the Jack Creek Fire remain in place. Weekly assessments will take place on possibilities of reducing area closures. The Stuart, Eightmile and Colchuck zones will remain closed through Sept 22, and will be reassessed.
