8/5/2026, 5:07:54 PM
Core Event
A fast-moving wildfire ignited shortly before 5:30 p.m. on Monday near Hogan Dam and Gann Road, close to New Hogan Lake in Calaveras County, California. The fire raced uphill through dry grass and brush, expanding rapidly. By late Tuesday morning the blaze had burned roughly 6,495 acres, with Cal Fire reporting no established containment and a moderate rate of spread.
Background & Context
Dry vegetation and seasonal conditions create a high fire risk, and the region has already faced multiple wildfires this summer. Smoke from the Gann Fire joined emissions from other California, Oregon and Nevada fires, reducing air quality as far away as Reno, Nevada.
Data & Statistics
- Acreage growth: 1,800 acres early-morning; 3,000 acres mid-morning; 3,760 acres at 10:55 a.m.; 6,495 acres at 5:38 p.m.
- Personnel and equipment: More than 250 firefighters, including Firehawk helicopters capable of night operations.
- Evacuation zones: Mandatory evacuations for zones CCU-147, CCU-139, CCU-110, CCU-109; zone CCU-130-B added later.
- Shelters: Red Cross shelter at Jenny Lind Memorial District (Valley Springs); livestock shelter at Calaveras County Fairgrounds (Angels Camp); pet-friendly shelter at 300 W Daphne Street (Valley Springs).
- Injuries and incidents: One firefighter injured in a dozer rollover; a pickup truck collided head-on with a fire engine, prompting CHP road clearance.
Official Statements & Responses
- The Calaveras County Sheriff proclaimed a local state of emergency, allowing the county to request additional state assistance.
- Governor Gavin Newsom announced federal funding secured for fire-response efforts.
- Cal Fire provided updates on acreage, containment status, and resource deployment.
- The City of Jackson closed its public pool because of poor air quality and ash.

On-the-Ground Reports
Residents in mandatory evacuation zones were instructed to leave immediately, while those in advisory zones were asked to monitor local guidance. Volunteers advised displaced families to bring medication, extra clothing, hygiene supplies, important documents and items for children. AlertCalifornia cameras captured visible black smoke on Tuesday morning. The dozer rollover and pickup-truck crash required CHP intervention to keep fire crews moving.
Why It Matters / Impact
The fire threatens homes on the mountain slope, prompting evacuations and disrupting schools and recreation facilities. Smoke contributed to moderate air-quality conditions in Reno, affecting people with asthma, older adults and children. The emergency declaration expands Calaveras County’s ability to obtain state resources, influencing suppression and recovery operations.
What’s Next
Cal Fire will continue to monitor the blaze, which remains without established containment, and keep suppression resources on scene. County officials will review the emergency proclamation and may seek further assistance as conditions evolve. Residents in evacuation zones are urged to stay informed through local authorities for any new orders or updates.
