The Thielsen Fire burning near Diamond Lake is at 6,700 acres and only 1 percent contained.
An update from the U.S. Forest Service said the Southern Area Incident Management Gold Team assumed command of the fire on Tuesday. The fire is within 1 mile of Diamond Lake Resort and 5 miles north of Crater Lake National Park. Level 3 evacuations are in place for the Diamond Lake, Lemolo Lake and Toketee Ranger Station areas.
The update said the spread potential for the fire is still high and firefighter safety remains a concern due to access to fire and steep terrain, including spread towards Cinnamon Butte. Crews plan to use direct attack where possible, using heavy equipment and firing as needed.
Although smoke may limit daytime heating and wind strength, dry and breezy conditions are expected each afternoon over the next several days, with gusty south to southwest winds. Overnight recoveries should generally improve through the week. The trough responsible for the breezy winds will slowly move onshore over the next few days, with chances for light precipitation increasing from west to east this week. There is a slight chance of thunderstorms on Thursday.
The fire was discovered September 8th and the cause of the fire is not yet known.
