In Level 1, residents are asked to monitor emergency information and be ready to evacuate if the need increases.
“Residents of Lowman must stay alert since the threat of wildfire is still present,” the Forest Service news release stated.
Also, Idaho 21 will reopen at 9 a.m. Tuesday between Idaho City and Lowman, restoring a major route into and out of Lowman, according to the news release. All portions of the Pioneer Fire adjacent to Idaho 21 have been contained, but motorists should expect to see smoke and even small flames in some areas that were blackened by the fire, the Forest Service reports. Downed trees also may be possible, especially when winds are strong.

The Sheriff’s Office announced Level 2 evacuations Friday, and about 35 people reportedly left their homes.

Firefighters on Sunday reopened Idaho 21 between Lowman and Stanley with a pilot car. The new Dry Creek Fire had closed that route Saturday along with Stanley Lake Campground. A new fire west of the Boundary Creek launch on the Middle Fork of the Salmon River threatened — but did not stop — whitewater rafters and kayakers from beginning the popular float trip there.
The Dry Creek fire had originally been estimated at 1,200 acres but after an infrared flyover Sunday the estimate dropped to 729 acres, said Julie Thomas, a Sawtooth National Forest spokeswoman.
The fire, which started near Dry Creek and forced officials to evacuate campers from Stanley Lake, sent spot fires over Idaho 21 into the Valley Creek drainage where there are ranches and vacation homes. Firefighters were confident they could make progress on the fire, Thomas said.
