Black Butte Ranch west of Sisters was warned Monday of a possible evacuation due to the growing Milli Fire. Several subdivisions west of Sisters remain evacuated.

The fire, burning since Aug. 11 9 miles west of Sisters, grew slightly Monday to 10,496 acres, expanding toward Lava Lake Camp and North Matthieu Lake in the Three Sisters Wilderness.

More than 640 firefighters continued to work Monday, but all ground and air efforts paused for about 45 minutes during the darkest part of the solar eclipse.

Air tankers are making multiple water drops along Whychus Creek near Three Creeks Lake Road. And fire crews are extending and strengthening fire lines along the north, east and southeast part of the fire to protect private property and neighborhoods still under an evacuation notice. The lightning-caused fire is 20 percent contained.

Hundreds of residents were ordered to evacuate in the Crossroads, Edgington/Remuda and Wildwing subdivisions, Peterson Burn Road area and along both sides of Three Creeks Lake Road about 1 mile south of Sisters from the junction of the Brooks-Scanlon Logging Road. Those evacuation orders are still in place.

Black Butte Ranch west of Cold Springs Cutoff Road, the subdivision of Tollgate and all areas between the McKenzie Highway and U.S. Highway 20 are being warned about a possible evacuation.

A public meeting is scheduled for 6 p.m. Tuesday at Sisters High School to provide the latest information on the fire, closures and evacuations.

While the Milli Fire burns, the 68,135-acre Nena Springs Fire in the Warm Springs Indian Reservation is winding down with no growth reported Monday. The fire is now 60 percent contained. Evacuation levels have been scaled back to warnings, so residents can come and go freely.

Crews are starting to extinguish hot spots, and remove trees and fire equipment from the site.
