NCW — The Cougar Creek Fire has shown little growth in recent days, but is still actively burning in its interior.
The 4,154-acre fire is burning 20 miles northwest of Entiat  in thick dead and down timber and is creeping and backing down steep rugged terrain, the Okanogan-Wenatchee National Forest wrote in a news release.
The fire is managed by a Type 1 incident management team from California and 677 personnel are assigned to the fire.
Spot fires on the east and south side are being worked so that existing roads and trails can be used to establish a continuous perimeter around the fire, the release says. The north and west sides of the fire are relatively stable and the east side near Tyee Ridge is holding.
On Sunday, crews installed sprinklers and portable pumps to protect homes in the Entiat Valley, removed brush and dead timber near homes in the Entiat Valley and Plain, linked containment lines, and burned vegetation along the south and southeast perimeter.
Level 2 evacuations (be set to leave) are in effect from Mad River Road to Entiat River Road milepost 24.5. Forest Service campgrounds remain closed, as does the forest closure.
The Lost Lake Fire, sparked several days ago by lightning about nine miles north of Plain, is estimated to be less than 50 acres. Crews, along with an air tanker, made an initial attack on Sunday, and on Monday 16 smokejumpers will assess the fire from the ground and help fire managers develop a strategy.
Officials are monitoring two more lightning-caused fires of less than 50 acres in remote areas: The Bannock Lakes Fire 17 miles west of Stehekin in the Glacier Peaks Wilderness, and the Whitepine Fire 19 miles northwest of Leavenworth in the Alpine Lakes Wilderness.
