More than 100 additional firefighters arrived late Friday to help contain the Nena Springs Fire, which has burned about 34,000 acres through the Warm Springs Indian Reservation.

The total crew of 240 firefighters increased the containment to 15 percent, as of Saturday afternoon. The firefighters are on pace to completely control the fire by Tuesday, according to the Oregon State Fire Marshal office.

But the region continues to be a hot spot for fires. The Central Oregon Interagency Dispatch Center reported 61 new wildfires since Thursday, some burning multiple acres and some burning individual trees.

Lightning-strike fires that started Friday at the southern base of Mount Bachelor, 10 miles south of Prineville and 4 miles west of Madras were extinguished Saturday, according to Patrick Lair, spokesman for the dispatch center.

But Lair said Saturday that crews are responding to a 50-acre fire burning about 2 miles from Black Crater, and east of the Lava Camp Lake Trailhead in the Three Sisters Wilderness. The Milli Fire is burning into the same land as the 2006 Black Crater Fire, Lair said.

“There is a lot of dead timber from the 2006 fire,” Lair said. “It’s getting real active this afternoon.”

Due to the Nena Springs Fire, residents in Schoolie Flat, Simnasho, and the S-300 subdivisions are being evacuated.

People in Kah-Nee-Ta Resort, the Charlie Canyon Subdivision, Wolf Point and the Fish Hatchery Grade area have been asked to be prepared to leave.

A Red Cross shelter is established at the Warm Springs Community Center to support people displaced by the fire.

Fire crews have contained a small section on the northwest end of the Nena Springs Fire, which started just after 5 p.m. Tuesday and is human caused. Air tankers and helicopters have been dropping fire retardant and water to slow the fire, and give crews a chance to build fire lines.

Several historic, unoccupied structures were lost in the first three days of the fire.

Highway 3 and S-300 Road are closed, except to local residents.
