A lightning storm in southwest Oregon started five new wildfires in the Umpqua National Forest, U.S. Forest Service officials said.

Four of those fires are less than an acre and one, Paradise fire five miles west of the forest, is 20 acres, Forest Service spokeswoman Cheryl Caplan said Tuesday.

Umpqua National Forest is at extreme fire danger, Caplan said. Campfires are restricted to campground fire rings and fireplaces in the wilderness.

The new wildfires started as several others burned across the state. The wildfires and hot, dry conditions prompted Gov. Kate Brown to declare a state of emergency last week. The declaration allows the Oregon National Guard to assist the state Department of Forestry and state Fire Marshal's Office.

The Oregon National Guard and the Forestry Department are fighting the Whitewater Fire in the Mount Jefferson Wilderness east of Detroit. The fire, started by lightning at the end of July, is burning at 5,515 acres.

Two helicopters dropped nearly 4,000 gallons of water on the fire Monday and 25 National Guard personnel were dispatched to the fire.

All trail access points into Jefferson Park are closed, including a 28-mile stretch of the Pacific Crest Trail.

Officials also closed the following areas:

· In the Willamette National Forest: Bingham Ridge, Minto Mountain, Pamelia Lake, Woodpecker Ridge, Whitewater Creek, Cheat Creek, Triangulation Peak, Leone Lake, South Breitenbush and Crown Lake

· In the Deschutes National Forest: Bear Valley/Rockpile Lake, Cabot Lake, Jefferson Lake and Brush Creek

Here's a rundown of other fires in the state:

Spruce Lake Fire:

The Spruce Lake fire near Crater Lake has burned 4,631 acres, but scattered rain is helping fire fighting efforts, officials said Tuesday. The fire, ignited by lightning on July 29, is 19 percent contained.

A level 1 evacuation notice remains in effect for Rim Village and Crater Lake Park headquarters. A level 1 notice means people should be ready to leave.

Several trails are closed in the area:

- Pacific Crest Trail from the south park boundary to Highway 62 and from the intersection of the Dutton Creek Trail to the North Entrance Road

- Union Peak Trail

- Stuart Falls Trail

- Pumice Flat Trail

- Boundary Springs Trail

- Bald Crater Loop Trail

- Bert Creek Trail

- Discovery Point Trail

- Lightning Springs Trail

- Rim Trail, from Discovery Point to North Junction

The area west of the fire on the Rogue River-Siskiyou National Forest is also closed.

Flounce Fire:

Gov. Kate Brown declared the 1,000-acre fire near Prospect a conflagration, meaning it is a large fire that threatens lives, health or property. The declaration, made Tuesday evening, allows the state fire marshal to mobilize resources to help local agencies battle the blaze.

Approximately 50 homes north of Lost Creek Reservoir were placed on level 1 evacuation notice.

The fire was started Monday by lightning.

Bear Butte Fire:

The nearly 500-acre fire outside Baker City forced the evacuation of the Anthony Lakes Resort. The Anthony Lakes area is closed along Forest Road 73 and the U.S. Forest Service closed a forest area around the fire. It is 30 percent contained.

The fire started Aug. 4. Its cause is unknown.

Cinder Butte Fire:

The Cinder Butte Fire, started by an unknown cause Aug. 2, covers 52,531 acres outside Burns. It is 80 percent contained.

The fire threatened five homes and 10 minor structures. It has destroyed four outbuildings.

Indian Creek Fire:

The 83-acre fire in the Columbia River Gorge has shown little fire activity in recent days, officials said. It started July 4. Its cause remains under investigation.

The southern part of the Eagle Creek Trail, Wahtum Lake and Indian Springs campgrounds and several other trails are closed.

Blanket Creek Fire:

The Blanket Creek Fire, ignited by lightning in late July near Prospect, is 4,739 acres. It is 36 percent contained.

Thunderstorms dampened parts of the fire, but it continued to burn dry timber Tuesday, officials said.

Crews are trying to prevent the fire from spreading further east in the Crater Lake National Park.
