CAL FIRE Investigators Determine Cause of “Wragg Fire”

CAL FIRE Investigators have determined the cause of the “Wragg Fire” was the result of a vehicle exhaust contacting dry grass. The dry grass ignited the surrounding brush and the vehicle as well.

The Wragg Fire was reported at 2:24 p.m. on July 22, 2015 off of Hwy 128 near Wragg Canyon Rd and the Lake Berryessa Dam.  The fire burned through heavy brush and steep rugged terrain eventually ending 4 miles west of the City of Winters and just north of Mix Canyon Rd near Vacaville.

During initial operations a CAL FIRE helicopter was used for the emergency rescue of multiple hikers in the Cold Canyon area. One hiker suffered a heat related illness and was transported to a local hospital by ground ambulance.

The fire burned 8,051 acres, destroyed 2 outbuildings, damaged 4 outbuildings, and 1 residence.  The “Wragg Fire” is 100% contained.

“With the critical fire conditions we are seeing this year combined with 4 years of drought, we are asking the public to be extra cautious in not sparking a wildfire”, said CAL FIRE Unit Chief Scott Upton.  “With hunting season and other outdoor activities at their peak it is imperative that we remain aware of how easily dry grass can ignite a wildfire with devastating consequences.”

With drought conditions, CAL FIRE continues to urge the public to be careful outdoors. Pulling over in dry grass can easily ignite a wildfire. Learn more tips on how to operate and maintain your vehicle safely at
