(Sweet Home, OR) -- The Oregon State Marine Board has temporarily closed Green Peter Reservoir near Sweet Home to boaters due to the Wiley Fire burning nearby. U.S. Forest Service Scooper planes need to use the lake to refill water tanks so they can help ground crews battling the fire. The fire has burned 10 to 20 acres in extremely steep terrain and the aircraft are providing major support. The Linn County Sheriff's Office has issued 'Level 1 - Be Ready' evacuation warnings for residents in the area.
