The Eagle Creek Fire is 28 percent contained. All suppression efforts are focused on protecting communities, infrastructure, and other values at risk. Protecting the Bull Run remains a top priority of the fire response.
Based on available data from the U.S. Forest Service, the Portland Water Bureau will continue to update the fire perimeter map at https://www.portlandoregon.gov/water/article/655188 as it becomes available. Based on new infrared imagery data from Sept. 15, the fire has burned approximately 100 to 150 acres inside the Bull Run Management Unit, but not inside the actual Bull Run watershed. The Bull Run reservoirs and water supply infrastructure are not near the areas that are currently estimated to have been burned. Please check this link periodically for updated maps on the fire perimeter in relation to the Bull Run watershed.
According to current estimates, less than 1 percent of the Bull Run Watershed Management Unit has been burned at the northern boundary.
The fire will continue to burn along the northern edge of the management unit until significant wet weather arrives, possibly beginning on Sunday. Weather is expected to remain cooler with light winds. Friday evening and Saturday may bring lower relative humidity and a shift to light northeast winds. Significant precipitation is still forecast for Sunday night and early next week.
Yesterday, aircraft dropped nearly 100,000 gallons of water on the fire. Crews will be constructing direct hand line and helicopter bucket drops may be used to cool hotspots in the northwestern edge of the management unit. No retardant has been used in the Bull Run watershed
The Water Bureau continues delivering 100 percent Bull Run water and monitoring indicates that water remains safe to drink.
Unless there are significant changes this weekend, you can expect the next update to come on Monday, Sept. 18.
