Cause of 15-acre Cartwright Fire released by Boise Fire

About 45 firefighters responded to a Friday morning grass fire that burned about 15 acres near Bogus Basin Road, according to Tony Piscopo, Boise Fire Department division chief for wildfires.

No structures were burned in the blaze, which was about 80 percent contained as of 11:30 a.m. No firefighters were injured in the response. Char Jackson, spokeswoman of the Boise Fire Department, said the fire was caused by a well pump electrical malfunction.

The fire — dubbed the Cartwright Fire — was reported at about 9:20 a.m. in the area that’s east of Cartwright Road and west of Bogus Basin Road. The fire was contained to all private land.

Crews worked throughout the afternoon to mop up the area that was contained. Full containment is expected by tonight, Piscopo said. First responders will not consider the fire totally extinguished until Saturday, he said.

He said did not know where exactly fire started.

Boise Fire is requesting the public avoid the area.

Bureau of Land Management firefighters also assisted the Boise firefighters because the area was near BLM land.

Two Bureau of Land Management helicopters responded to the scene to dump water, while two single-engine airplanes dropped retardant in the area.

Boise Fire reported that the Cartwright Fire was the largest fire in the city limits so far this summer.

At least nine Boise fire brush engines, three structure engines and two trucks responded to the scene.
