Sunriver was reduced to a Level 1-Be Ready evacuation notice Thursday morning, as rains improved conditions on the 10,332-acre Bachelor Complex Fire.

The Bachelor Complex Fire is a group of about 30 smaller fires ranging in size from one tenth of an acre to more than 1,000 acres near Mount Bachelor and surrounding areas.. Included is the Little Lava Fire, which is burning approximately 2 miles southeast of Little Lava Lake to the west of Sunriver.

The cooler wet weather has slowed the spread of the Little Lava Fire, which had jumped to nearly 10,000 acres by Wednesday before the rains set in, but officials say the rain was not enough to have a lasting effect on the fire. Although crews made “good progress toward securing the fire’s east edge” with dozer lines, fire activity was expected to be moderate throughout Thursday, according to a news release from incident commanders.

Burning north of Fort Rock and east of La Pine are the Firestone and Flat Top fires, which also started on Sept. 6 due to lightning. The Flat Top Fire was 30,643 acres as of Thursday and the Firestone Fire was 8,787 acres. According to fire officials, there was no increase in the size of the Flat Top Fire Wednesday night, and during the day, firefighters were able to get most of the western edge of the Firestone Fire secure.

While temperatures are expected to be lower this week, fire officials warn that the vegetation beneath the tree canopy remains dry and that the Bachelor Complex Fire still has an active perimeter. The rain yesterday had a greater effect on The Backside, 892 and 911 Fires, which are also part of the Bachelor Complex Fire, and officials predict mild activity in those areas. Scattered showers were predicted across all fire areas in Central Oregon for Thursday.

Mt. Bachelor ski area said it would remain closed on Friday due to firefighting activities.
