If you're seeing smoke in the direction of Sisters, it's from about a 40 acre fire that started around 1:45 today in the Wychus Creek area. Officials are calling it Incident 815. Valerie Reed is with the Central Oregon Dispatch: "We have quite a few engines. We have an air attack that air tankers are dropping and some helicopters are doing some bucket drops there." Reed says the weather is cooperating, and it is not spreading too quickly, and no structures are threatened at this time.  She says they don't know how it started, but investigators are on the scene now. The fire is burning west of Crooked River Ranch, between Sisters and Lake Billy Chinook in dense brush.
