A fast-moving vegetation fire near New Hogan Lake had burned roughly 100 acres by Monday evening, pushing rapidly uphill through dry grass and brush in Calaveras County. The blaze remained at 0% containment in the latest public update, with no evacuations or threatened structures reported at that point.
The Gann Fire started around 5:27 p.m. Monday near Hogan Dam Road and Gann Road on the southeastern side of the lake, in the Valley Springs area, according to CBS Sacramento. CAL FIRE listed the cause as under investigation and reported the fire at about 100 acres.
Fire officials described the blaze as spreading at a dangerous rate through grass and brush, with rapid uphill fire behavior. The official CAL FIRE incident page said additional firefighting resources were ordered, while hose lines were being extended up both flanks of the fire.
Evacuation Picture Remained Fluid Monday Night
As of about 6:30 p.m. Monday, no evacuation orders had been issued and officials had not reported any threatened structures, CBS Sacramento reported. Residents and visitors were urged to avoid the area so engines, aircraft and other emergency resources could move freely while crews worked to slow the fire.
Calaveras Consolidated Fire joined the response, adding local resources to the CAL FIRE-led firefight. The fire’s location near the reservoir is familiar ground for emergency planners: a Calaveras County emergency plan lists a separate 2023 Gann Fire near Valley Springs that burned 105 acres, along with several other wildfires near New Hogan Lake.
Dry Foothill Fuels Keep Fire Risk Elevated
CAL FIRE’s current seasonal outlook says significant fire potential is expected to remain normal to above normal through September in mountainous areas, while dead and live fuels continue drying through the summer. That backdrop helps explain why a vegetation fire that begins in the foothills can add acreage quickly, even before officials know whether homes or evacuation zones will be affected.
The Gann Fire’s cause had not been determined in the latest incident information. Residents should monitor Calaveras County emergency alerts and CAL FIRE updates for any changes to evacuation guidance, road access or containment.
