Firefighters from across Northern California, including resources from neighboring Sacramento-area and Sierra foothill communities, continue battling the Gann Fire in Calaveras County after the wildfire nearly doubled in size overnight, surpassing 7,000 acres.
According to CAL FIRE’s Wednesday morning incident update, the wildfire has burned 7,052 acres and is 10% contained. The firefighting effort has expanded dramatically since the fire ignited Monday evening, with 1,623 personnel now assigned to the incident, including engines, hand crews, bulldozers, helicopters and fixed-wing aircraft working to protect homes, strengthen containment lines and limit additional fire growth.
Cal Fire has arrested a Valley Springs man on suspicion of starting the fire Herbert Wayne Smith, 65, was arrested Monday evening near the fire’s reported point of origin along Hogan Dam Road.  He was booked on suspicion of unlawfully causing a fire that burned structures or forest land and reportedly posted bail Tuesday.Â
The fire is now under the unified command of CAL FIRE Incident Management, bringing expanded state resources to the incident. Firefighters from CAL FIRE, local fire agencies and departments operating through California’s mutual aid system, along with state and federal partners, continue working around the clock. Resources from neighboring Sacramento-area communities, the Sierra foothills and surrounding counties are among those assisting in the regional firefighting effort.
The Gann Fire ignited shortly before 5:30 p.m. Monday near Hogan Dam Road and Gann Road southeast of New Hogan Lake near Valley Springs. Fueled by triple-digit temperatures, low humidity and critically dry vegetation, the wildfire spread rapidly through grass, brush and timber. After burning approximately 3,760 acres Tuesday, the fire nearly doubled in size overnight before firefighters established their first containment lines Wednesday morning.
Firefighters made measurable progress overnight as fire behavior moderated somewhat, allowing crews to strengthen containment lines and conduct more direct attacks on the fire. Aircraft mapping also provided a more accurate measurement of the fire perimeter, resulting in the updated acreage estimate. Firefighters are focusing Wednesday’s operations on direct line construction while taking advantage of a slight increase in humidity and modestly cooler temperatures.
The wildfire continues burning across a largely rural area stretching south of San Andreas toward Copperopolis and around the Salt Spring Valley Reservoir. Steep terrain, dense vegetation and limited road access continue challenging suppression efforts, requiring firefighters in many areas to construct containment lines by hand and with bulldozers.
Mandatory evacuation orders remain in effect for multiple communities surrounding the fire, including areas near Valley Springs, Campo Seco, Toyon and New Hogan Lake. The Calaveras County Sheriff’s Office has also expanded evacuation warnings to include zones CCU-111, CCU-131, CCU-148 and CCU-153, advising residents in those areas to remain prepared to leave should conditions worsen. See current evacuation map here.
The Calaveras County Sheriff’s Office continues operating under a local state of emergency proclaimed Tuesday as the wildfire threatens homes, ranches and infrastructure throughout the region.
CAL FIRE has confirmed that multiple homes and other structures have been destroyed, although a comprehensive damage assessment remains underway. Damage Inspection Specialist (DINS) teams continue evaluating impacted properties while firefighters prioritize structure protection in the northern and eastern portions of the fire near Pool Station Road, where homes remain threatened.
The American Red Cross continues operating an evacuation shelter at the Jenny Lind Veterans Memorial District, 189 Pine St. in Valley Springs, for displaced residents. The Calaveras County Fairgrounds at 2465 Gunclub Road in Angels Camp remains open as a livestock evacuation center, while additional sheltering is available for household pets and other domestic animals.
Several road closures remain in effect around the incident, including portions of Pool Station Road, Hogan Dam Road and access to the Bear Creek Day Use Area. Officials continue urging the public to avoid the area to provide firefighters and emergency equipment unrestricted access.
The wildfire continues affecting communities beyond the immediate fire area. Calaveras Unified School District campuses remain closed Wednesday because of the fire, while smoke from the incident continues drifting into portions of Sacramento and El Dorado counties, creating hazy skies at times in the Folsom area.
Firefighters have also faced hazards while battling the blaze. One bulldozer operator sustained a minor injury during the initial attack and was transported for medical evaluation. No civilian fatalities have been reported.
Although firefighters have established 10% containment, the wildfire remains active and continues burning under challenging conditions. Containment reflects the percentage of the fire’s perimeter where control lines have been established and are expected to hold, while firefighters continue working to strengthen those lines and prevent further spread.
CAL FIRE currently estimates full containment of the Gann Fire on Aug. 18, although that projection remains subject to change based on weather, fire behavior and operational conditions.
