WA wildfire update: Pioneer Fire continues to impact Lake Chelan

The Pioneer Fire continues to burn in the Lake Chelan-Sawtooth Wilderness near the north shore of Lake Chelan. Unfortunately, this fire will likely be a long term event; people in the area should expect intermittent air quality impacts as the fire spreads. The map at the top of this page now shows a box around the fire location--this box indicates that there is now a daily smoke outlook issued by an Air Resource Advisor for the Pioneer Fire. Clicking on the link in the box will take you to the smoke outlook, or it's accessible by clicking on the Local Smoke Outlooks tab on the blog.

Over the weekend high winds led to the fire doubling in size as well as variable smoke impacts in the area. The Chelan area saw mostly moderate smoke impacts, but areas east of Lake Chelan in the Methow observed unhealthy and worse air quality impacts on the evening of June 15:

Winds pushing smoke to the southeast today will cause moderate air quality impacts in Chelan and Manson. Breezier winds tomorrow and warming temperatures will increase fire growth and lead to air quality index values ranging from moderate to Unhealthy for Sensitive Groups.

Across the region, the Beam Road Fire east of Zillah is 42% contained; evacuations have been reduced and air quality impacts have been minimal. After causing moderate smoke impacts in the Lewiston-Clarkston area last Friday, the Nisqually John Fire is now 100% contained.

As always, keep an eye on air quality conditions and the smoke forecast, and we'll update the smokeblog as needed. 


  1. Great work ! Thanks for all that you’re doing !

  2. hope the rain comes and puts out the fire starts. thanks for this info!

  3. Is the slightly decreased air quality forecasted on the 4th from wildfire smoke or firework smoke? Thank you!

    1. Puget Sound Clean Air Agency is forecasting moderate air quality for the 4th of July, since fireworks are expected. Typically we see air quality in Pierce county (and other locations) get especially bad late at night and into the following morning.
