First discovered: 6 weeks ago, 2:37 p.m. July 1

Initial location: 13 miles east of Lakehead, CA, Shasta County, Calif.

Fire unit: Shasta-Trinity National Forest

Fire type: Wildfire

Fire name: Green Fire

Green Fire initially started 2:37 p.m. July 1 in Shasta County, California.

Since its discovery six weeks ago, it has burned 19,022 acres. As of Sunday afternoon, a fire crew of 14 has achieved full containment of the blaze. The fire is assumed to have been triggered by lightning.

Fuels involved in this wildfire, according to InciWeb: “Brush (2 feet), Hardwood Litter & Timber (Litter and Understory) Narrative: The fire area has continuous fuels with variable fire history exceeding 50 years. This has resulted in heavy loading of brush and timber, creating conditions to produce fire behavior with high resistance to control. Primary growth occurred when energy release component (ERC) values were above the 80th percentile with higher resistance to control observed when ERCs were above the 85th percentile. Northern slopes at higher elevations have fir overstory with black oak, dogwood and bigleaf maple. Rocky areas have less continuous fuels, and there are chaparral areas including Mountain Mahogany, oak species, and California buckeye. Fuel model TU5 (165) has been used for fire behavior runs. The northern extent of the fire is adjacent to the October 2024 Shoe Fire where fuel loading is much lower and considered a fuel model TL1 (181) where fire behavior was minimal. The southwest portion of the fire has burned into an area with a history of prescribed fire where fuel model TL6 (186). The fire area received about 1/3 inch of rain July 25th which helped moisten fuels, however a modest drying occurred July 26th-31st. 30 .”

Historic data

According to NIFC figures for 2024, lightning-induced fires in California numbered 305, scorching 90,206 acres of wildland.

Incident description

Firefighters are engaging in a full suppression strategy in steep and rocky terrain utilizing aircraft and existing dozer lines from the 2024 Shoe Fire. Control objectives are to keep the fire north of Pit River, southeast of Sulanharas Creek, and southwest of Fenders Ferry Road.

“QUICK LINKS: Daily Update Daily Map Facebook: (New)Shasta-Trinity NF Fire and Aviation Shasta Trinity National ForestX.com @ShastaTrinityNFPublic Information: (530) 685-05362025.green@firenet.govwww.fs.usda.gov/r05/shasta-trinityGREEN FIRE August 17, 2025 Update: The Green fire is at 19022 acres and 100% containment has been achieved. Resources continue suppression repair and backhaul of equipment and supplies no longer in use. Mopup and patrol of the Pit River Arm will continue as needed. Suppression repair continues on the 35N02 road and Curl Ridge. Fenders Ferry Road from Pitt 6 bridge to McCloud Campground will remain closed while crews complete the culvert work on the road. The culverts are being repaired at Goose Gap near the east fork of Bills Creek. FIRE ACTIVITY: Minimal fire activity is expected. FIRE WEATHER: Near to below normal temperatures are forecast across the Green Fire through Monday with rising relative humidity. There is a 20% chance of showers or thunderstorms on Saturday and Sunday, followed by a gradual warming and drying trend. EVACUATIONS: noneCLOSURES: Shasta-Trinity National Forest closure order for the Green Fire can be found at https://www.fs.usda.gov/r05/shasta-trinity/alerts/green-fire-closure-order. INITIAL SITUATION: The Green Fire started following widespread thunderstorms and lightning on the afternoon and evening of June 30, 2025. The Shasta-Trinity National Forest saw more than 3,100 lightning strikes between June 30 and July 2, resulting in several wildfires. (Wildfire information for other current incidents on the Shasta-Trinity). Firefighters will continue monitoring the forest in the days ahead for holdover fires that may emerge from this week’s storms. AIR QUALITY: Fire activity for the Green Fire is continuing to decrease. Areas close to the fire could see brief periods of smoke, but no long duration impacts are expected. NO DRONE ZONE: Drones pose a serious risk to firefighting and can cause air operations to cease. When drones interfere with firefighting efforts, a wildfire has the potential to grow larger and cause more damage. For more information on drones the public can visit the FAA’s website at www. KnowBeforeYouFly.org “If you fly, we can’t! ”.”

• Projected incident activity:

“12 hours: Minimal fire activity is expected. 24 hours: Previously identified threats have been greatly reduced and not additional impacts are expected. 48 hours : Any remaining fire activity will likely be limited to smoldering or low-intensity burning well within the interior. 72 hours : Previously identified threats have been greatly reduced and additional impacts are expected unless fire behavior increases significantly.  Fire will continue to consume unburned fuels while crews mop up, reinforce primary control lines, and conduct suppression repair work. Minimal fire activity is expected after the next 72 hours. Cooling trends late next week will help reduce smoke production.”

• Planned actions on this wildfire:

“Continue suppression repair and backhaul of equipment and supplies no longer in use. Mop up and patrol of the Pit River Arm will continue as needed. On the western flank, resources will continue to mop up along the 35N02 Road system in Branch V to reinforce containment line. Suppression repair continues on the 35N02 road and Curl Ridge.”

• Weather concerns:

“Weather Synopsis :  A gradual warming and drying trend is favored for next week.  Sunny, maximum temperature 92-96. Minimum humidity 20-24%.”

• Significant events:

“Minimal Creeping Smoldering”

• Other remarks:

“A Type 4 IC organization is now in place. ICT4 Jake Koschik and ICT4(t) Zach Miller. Morning briefings will be held in-person at 0700 at the Shasta Lake RD office, 14225 Holiday Road, Redding, CA 96003. Fenders Ferry road continues to be closed past McCloud Bridge Campground to Pitt River Bridge near PGE – Pitt 6 dam.”

Fire containment

What does 100% containment mean?

Note that full containment doesn’t mean the fire is completely out. In this case, it means that the whole perimeter of the wildfire has been surrounded by a control line and it is now stopped from spreading. A fully contained wildfire may continue to burn within the containment perimeter but is not likely to spread.

However, there’s a significant difference between containing and controlling a wildfire. After the fire is fully contained, the next step is to control it. Controlling a fire means ensuring that the fire can’t spread or cross the containment line.

Containment is part of a larger plan for managing a wildfire. It is normally expressed as a percentage and it refers to how much of the fire perimeter has been surrounded/enclosed by a control line that firefighters create. The containment percentage indicates a certain level of control, but it doesn’t always correlate to safety level. Also, it’s important to note that containment doesn’t mean a fire is out.

How is containment measured?

The incident’s central command constantly receives progress reports from firefighters on the ground. As the fireline is constructed, inspected or reinforced, mappers record those details to adjust the containment percentage. The percentage tells the public how much of the fire perimeter is believed to not go beyond the control lines.
