Situation Summary

What Happened

The fire started off of Berryessa Knoxville Road, burning in light and flashy fuels at a moderate rate of spread. The fire ran uphill into the steep and rugged terrain, with winds in alignment with the topography. The four air tankers and two helicopters were able to slow the spread of the fire at a ridgetop, aiding the ground crews as they constructed control lines with the use of dozers and hand crews. Forward progress of the fire was stopped at 12:25 p.m.

The biggest challenges fighting this fire were the steep terrain and the heat advisory that was in effect. Temperatures at the fire were 98 degrees with 11 mph winds and 27 percent relative humidity. Those factors pre-heated the fuels, allowing the fire to grow rapidly.

During the height of the fire fight, there were 10 engines, five water tenders, three dozers, two hand crews and approximately 80 total personnel.

The fire was 100 percent contained by Sunday evening on Aug. 10.
