Direct handline and dozer line construction continue to be reinforced and mopped up across all divisions to secure containment and reduce
the potential for rekindles. Current resource needs are focused on maintaining sufficient engines, crews, and tactical water tenders to complete mop up, hold
containment lines, support firing operations, and begin suppression repair as conditions allow. Anticipated results include continued improvement in
containment, reduced fire activity, successful completion of remaining firing operations, and the initiation of suppression repair and phased resource
demobilization over the next several operational periods.
Firefighters continued suppression efforts on the Gann Fire yesterday focusing on the firing operation and strengthening control lines. Active fire behavior remained a challenge in critically dry fuels. Hot, dry conditions are expected to persist through the coming days, with temperatures above 100 degrees. Containment continues to increase despite challenging conditions.

Fire cause has been changed to equipment use.

Last night a firing operation began that will continue on today. This is a firefighting tactic used to remove unburned fuels to help contain the fire. It is expected to complete today, and additional smoke may be visible during this time. The Gann Fire is now 9,363 acres and 10% contained.
August 5, 2026 at 7:21 AM
Direct line construction will be the focus of today’s efforts. A slight decrease in temperatures and increase in humidity are expected today. The incident will transition command to CAL FIRE IMT 6 this morning.
August 5, 2026 at 7:07 AM
Yesterday, fire behavior was driven by critically dry fuel conditions in oak woodland transitioning into timber. Energy Release Component (ERC)
values are forecast to remain at historic critical levels over the next seven days, with both 100-hour and 1,000-hour dead fuel moistures remaining above
critical thresholds. A persistent high-pressure system produced excessive heat, with temperatures in the upper 90s and minimum relative humidity near 20
percent, supporting active surface fire, uphill runs, and increased resistance to control during the afternoon burn period.
August 4, 2026 at 9:22 PM
Fire activity has decreased this evening. Night flying helicopters will be supporting firefighters throughout the night. A firing operation took place this afternoon on the western edge of the fire.

CAL FIRE Incident Management Team 6 has been assigned to the Gann Fire in Calaveras County to support the CAL FIRE Tuolumne-Calaveras Unit and ongoing suppression efforts.
The Amador Air District and Amador County Public Health have issued a joint air quality advisory to notify the public of the potential for poor air quality conditions due to smoke from the Gann Fire currently burning in Calaveras County.
Wildfire smoke can vary across Amador County, with air quality affected by wind direction and levels of particulate matter. Amador County Public Health advises that wildfire can affect everyone, not just those with existing health conditions. While people with chronic illnesses, young children, pregnant individuals, and older adults may be more vulnerable, all residents can experience health impacts from smoke exposure.
If you smell or see smoke, avoid unnecessary outdoor activities. Wildfire smoke can irritate your lungs, cause inflammation, affect your immune system, and make you more prone to lung infections. Symptoms may include, but are not limited to, coughing, watery and itchy eyes, headache, scratchy throat, and difficulty in breathing.
Take the steps below to protect your health:
- Minimize outdoor activities.
- Stay indoors with windows and doors closed.
- Do not run fans that bring smoky air inside (such as swamp coolers, fresh air ventilation systems).
- If you have a wall unit air conditioner or when in a vehicle, set AC to โre-circulateโ
- Do not smoke, fry food or do other activities that that will create indoor air pollution.
- If you have chronic health conditions, monitor your health closely. Contact your health provider if your symptoms worsen, including repeated coughing and wheezing.
- If you are experiencing a health emergency, call 911.
The Amador Air District and Amador County Public Health will continue monitoring the air quality in the county and will provide additional advisories as air quality conditions evolve.
