The Substation fire, which burned up thousands of acres southeast of The Dalles, is 92 percent contained.

The fire perimeter has also been reduced from 80,000 to 78,425 acres after more accurate mapping was used, fire officials announced on Facebook Monday morning.

Little fire activity was seen Sunday, but some areas along Eightmile Canyon and the Deschutes River are still smoldering as the hot, dry weather continues, officials said.

All evacuation areas in Sherman and Wasco counties were reduced to level one (get ready) Sunday morning.

The towns of Biggs, Rufus, Wasco, Moro and Grass Valley have since been downgraded to a zero, while Kent remain at level one, the Sherman County Sheriff's Office announced on Facebook Sunday evening.

Fire spokesman Kale Casey said there was zero fire movement Saturday and no fire-related road closures as of Monday morning.

As of Monday morning, 65 firefighters remain on scene, Casey said.

The Deschutes River is open again, but Casey warned people to be careful when camping and boating in the area as there may be some hot ash pits.

"People still need to be vigilant and very very cautious because this is going to be a horrific fire season," Shawn Payne, emergency manager for the county, said Sunday.

Type 3 Incident Commander Kenny Gaynor said some smoldering from trees and other objects is expected through the next week, but he encourages anyone who sees significant smoke or flames to call Central Oregon Interagency Dispatch at 541-316-7700.

The most recent count on damaged structures included four primary structures and four secondary structures, Casey said. A damage map is being put together to help with rebuilding.

While there was no damage to wind turbines, some of the buildings on the electrical grid were impacted, Casey said.

The cause of the fire is still under investigation by the Wasco County Sheriff's Office.

Though outside fire crews are heading back to their own communities, local resources will remain in place, said Lt. Damon Simmons with the Oregon State Fire Marshal's Office

"Right now the situation is looking good," Simmons said.

There will be a community resources meeting regarding the fire on July 30 in The Dalles, Casey said.
