The fire was first reported around 1 p.m. when the Mount Konocti Lookout reported seeing a quickly building column of gray smoke in the direction of the city of Clearlake.
Firefighters initially were unable to locate the source of the smoke. However, they soon tracked it down Dam Road and found it on private property near the Cache Creek Dam, according to Lake County Fire Chief Willie Sapeta.
When firefighters first arrived on scene, it was estimated to be about three acres, with a slow to moderate rate of spread in heavy fuel, based on radio reports.
A total of seven engines from Lake County Fire and Cal Fire responded, along with two water tenders, a dozer, air attack and three company officers, Sapeta said. Copter 104 from Boggs Mountain Helitack also worked the fire.
Radio reports stated there were some high voltage power lines on fire, but no dropped lines. The lines later were deenergized.
The fire burned in the scars of the 2015 Rocky and 2016 Clayton fires and an afternoon west wind was pushing it, according to reports from the scene.
At the scene, Sapeta asked that Yolo County Flood Control & Water Conservation District, which owns and operates the dam, be contacted and respond.
Forward progress was reported stopped at 2:25 p.m. At that point it was 5-percent contained.
Sapeta said the burn size was about 5 acres at the time he left. A later radio report at around 7 p.m. gave a size estimate of nine acres.
Sapeta said there was no harm to structures or firefighters, and the cause and origin remain under investigation.
Also on Monday, at about 3 p.m., firefighters responded to a structure fire in the 1400 block of Big Valley Road, where firefighters found smoke coming from the garage.
Radio reports stated that propane tanks were involved and high voltage lines were down briefly. Law enforcement was requested to come and close the road briefly while firefighters were at work.
The fire was knocked down quickly, with incident command reported to be clearing the scene shortly after 5 p.m.
