CACHE CREEK WILDERNESS AREA – A fire that has burned this week in wilderness areas in Lake and Colusa counties is expected to be fully contained on Friday.

The Oasis Fire, which broke out on Monday, has burned 1,400 acres on Bureau of Land Management land in the Cache Creek Wilderness Area and in the Northshore Fire Protection District. It's located south of Highway 20 and six miles west of Highway 16.

The cause of the fire remains under investigation. Cal Fire report suppression costs to date have totaled $2.4 million.

Late Thursday the fire was reported to be 80-percent contained. Cal Fire officials said containment efforts, along with and mop up and patrol of the fire, are continuing.

Air tankers and helicopters, as well as bulldozers, have played a major role in the fire suppression effort this week, as road access to the fire area was limited, according to reports from the scene.

On Thursday evening, reports indicated that the remaining aircraft that were being used to fight the fire would be released on Friday morning.

Resources from Cal Fire, Northshore Fire, Williams Fire Department, BLM and the Department of Corrections and Rehabilitation totaled 1,114 firefighters – of which 1,059 were with Cal Fire – and 40 engines, 43 fire crews, eight helicopters, 15 bulldozers and 14 water tenders.
