The Oregon Department of Environmental Quality has declared the air in the area unhealthy for sensitive groups.
Larry Calkins is with the Air Quality program in Bend.
"What we found was rather high numbers in Bend for sensitive groups like children, the elderly, those with asthma, respiratory problems or heart ailments."
The air in Bend and Klamath County are being called "unhealthy" for these groups.
People should try to avoid being outside and close their windows to limit exposure to the smokey conditions.
