Trail Creek, Alder Creek, & Sand Lake Fire Updates 10/04/2021

TRAIL CREEK FIRE | Start Date: July 8, 2021 | Cause: Lightning | 61,990 acres | 67% complete: With warmer temperatures, lower humidity’s, and higher winds, expect more active fire behavior in areas still holding heat, including Smithy, May, and Nugget creeks. If conditions are right, interior pockets may burn together but the perimeter should hold. Suppression repair work has begun in most areas of the fire including some road grading. Firefighters continue to monitor Nez Perce Creek and around Morgan Jones Lake where little heat remains. Yesterday, a Type 1 Chinook helicopter supported efforts in Nugget Creek, dropping approximately 60,000 gallons of water throughout the day. On the southeastern side, crews are pulling hose off the ridge and emptying water tanks.

ALDER CREEK FIRE | Start Date: July 8, 2021 | Cause: Lightning | 36,905 acres | 43% complete: The Alder Creek Fire may see increased fire behavior in areas still holding heat, including Christiansen and Osborne creeks. With the critical fire weather conditions today and tomorrow, the Osborne spot fires have the potential to burn back into the black of the main fire and smoke columns may become visible. Otherwise not much growth is expected. Crews will pull out and monitor the fire in Tucker Creek due to the increased winds and dangerous snags in the area. In the areas north and south of Sawlog, and the eastern perimeter, crews

are patrolling, doing suppression repair, and putting in water bars where needed.

SAND LAKE FIRE | Start Date: September 1, 2021 | Cause: Unknown | 228 acres:

Fire growth and activity on the Sand Lake Fire has been minimal and is being monitored by air.

WEATHER/FIRE BEHAVIOR: Monday, temperatures will be in the low-70’s, humidity’s will drop into the single digits or low-teens, and southwest winds will increase to 10-15 mph with gusts 30-35 mph, bringing critical fire weather conditions. Fire activity will pick up in areas still holding heat. Wednesday, an unsettled weather pattern will bring colder, more humid weather with chances of precipitation.
