Active Incidents

The Sourdough Fire north of Diablo Lake started on Saturday, July 29. It is currently burning in the Ross Lake National Recreation Area within the North Cascades National Park Service Complex, in very steep terrain. Air quality in the area is very bad in places, see here for local info. If you choose to travel in the area, please do not stop on the highway to take pictures or look at the fire. Do not fly drones in the area, as this will ground the helicopter and air tankers working on the fire. As of this week it was 6,280 acres and 25% contained. More information on what trails and campgrounds are open can be found here and here.

Hwy 20 is open. This remains an active fire area and the road is subject to closing again with little notice based on fire behavior, fire mitigation strategies or weather. Travelers along SR 20 are advised they may encounter firefighting personnel and apparatus along the highway and are discouraged from stopping along this stretch of highway. Traffic control is in place for the safety of the traveling public and should be observed.    

Road closure information is posted in the WSDOT real-time travel center and @wsdot_north and @wsdot_east on X/Twitter and updates will be provided as available. Details about recreation in this area including trail, area and camp closures are available on the North Cascades National Park Service complex website and the U.S. Forest Service alerts website.
