The Jack Fire located on the Umpqua National Forest started on July 5, 2021 at approximately 5:00 p.m. It is a human-caused fire. Warm dry weather, fuel types and steep terrain contributed to rapid fire growth. Initial attack efforts included the U.S. Forest Service, Oregon Department of Forestry (ODF) and Douglas Forest Protection Association (DFPA). Highway 138 was initially closed between Steamboat and Dry Creek Store.
By July 8th, the Fire grew to 4,224 acres with 0% containment. The Fire was in Unified Command with Northwest Incident Management Team 9 (NWIMT-9) and the State of Oregon Office of the State Fire Marshal (OSFM) Blue Incident Management Team (IMT). Within three days, the Jack Fire was at 10,937 acres. Steep terrain, warm temperatures and low relative humidity aided in fire growth.
On July 13th the Fire had somewhat stabilized. OSFM Blue IMT demobilized, and management of the Jack Fire was transferred back to DFPA. Structure protection was monitored by DFPA and NWIMT-9. The fire continued to grow, reaching 16,667 acres and 25% containment on July 16th. Evacuation levels were reduced, and Highway 138 was re-opened to the public. On July 19th, 50% containment was achieved and the fire was estimated to be 17,994 acres.
On July 30th the fire was at 23,004 acres with 63% containment. Multiple storm cells passed over the area through the night and ignited approximately 22 new fires. The Rough Patch Complex was established about 10 miles north of the Jack Fire to help manage the bulk of the new starts. Initial attack crews from the Jack Fire and Umpqua National Forest worked to suppress them. August 2nd, additional storm cells passed over the area and ignited 15 new fires. Four of the new starts were successfully contained by initial attack, and the rest of the new fires were assigned to the Rough Patch Complex.
Higher humidity and lower temperatures limited August 5th fire growth to less than 100 acres and the Jack Fire reached 23,280 acres with 54% containment. For the next 10 days a high-pressure system hovered over the fire area creating a sustained inversion. This resulted in moderate fire activity and growth. Firefighters were able to hold the fire inside containment lines on the west, northwest, and northeast sides of the fire. During this time, the Great Basin IMT Team 2 took command of both the Rough Patch Complex and the Jack Fire.
Northern Rockies IMT Team 1 assumed command of the Jack Fire on August 28. Great Basin Team 2 again assumed command of the Jack Fire on September 10.
Northwest Team 7 assumed command of the Jack Fire on September 24. Multiple days of precipitation have reduced the fire behavior and suppression tactics shifted to suppression repair.
On October 1, Rocky Mountain Area Type 2 Blue Team assumed command of the fire with the intent of reducing the footprint of the complex and continuing suppression repair efforts.
The Jack Fire is being managed under a full suppression strategy. Public and firefighter safety is the number one priority. In addition, protection of communities, timber resources, private property, highway corridors and recreational improvements are key considerations.

Closed Timber LitterTimber (Litter and Understory)
Douglas-fir overstory with a mix of both high load conifer litter and understory of brush and small trees. Portions of the fire area include older high severity burn scars with mostly brush, snags, and downed tree boles.
The fire is burning on steep ground in timber. Residual effects of recent precipitation and successful suppression action has reduced fire behavior to isolated smoldering in h heavy fuels.
Patrol highway 138 for fire impacts. Suppression repair as conditions allow.
|Projected Incident Activity|
Cool, damp weather will keep fire behavior at a minimum.
Incident is being managed by Rocky Mountain Blue Team along with Rough Patch Complex.
Today: Cold and clear to start the day. Once the sun rises, temperatures quickly warm to a few degrees higher than Monday. Clouds will also increase through the day. A cold front reaches the area by 2400 hours with rain/snow showers post-frontal into early Wednesday morning.
Tomorrow: Precipitation diminishes before 0800 hours with about 0.3 inches of liquid equivalent total. Clouds will gradually clear late day with cooler temperatures. Winds will be breezy out of the northwest.
Thursday through Saturday: Warmer and drier through the period with temperatures reaching the mid-60s in valleys, cooler at higher elevations.
