The Thielsen Fire burning near Diamond Lake is at nearly 7,800 acres and is 1 percent contained as of Wednesday afternoon.

An update from the Umpqua National Forest said level 3 evacuations remain in place for the Diamond Lake, Lemolo Lake and Toketee Ranger Station areas.

The spread potential for the fire is still high and firefighter safety remains a concern due to limited access, steep terrain and spread towards Cinnamon Butte. On Wednesday, crews focused on direct attack, point protection for critical infrastructure and securing and holding the southern edge of the fire near the northern edge of Diamond Lake. Smoke over the fire is inhibiting air operations, although some missions have been completed. Execution of the planned containment lines along the western edge will require hand crews where dozers cannot be used.

The Umpqua National Forest, including the Diamond Lake Ranger District, is closed until further notice due to unprecedented fire activity. Just under 300 people are working on the Thielsen Fire.
