A controlled burn that got out of hand in Lake County consumed more than 300 acres Tuesday.

The wildland fire in the Kelseyville area was moving up thick brush on Mount Konocti and not threatening any structures, according to Cal Fire Capt. Jeff Gahagan.

The fire, which was reported just after 11 a.m., was only about 10 percent contained by afternoon.

"We're getting several escaped control burns today for some reason," he said.

Even though the area has received above-average rainfall this season, the vegetation has dried since the last storms.

"The last rainfall was quite awhile ago and everything is pretty dry," Gahagan said.

Fire crews reached the blaze at Highway 29 and Red Hills Road. A helicopter, six fire crews, three bulldozers, eight fire engines and two water tenders were dispatched by Cal Fire. The South Lake County and Kelseyville fire departments also were assisting.

There was no estimate when the fire would be brought under control. Gahagan said crews would be there overnight and today.
