The Eagle Creek Fire perimeter grew modestly overnight, with limited growth in the Bull Run Watershed Management Unit. The fire is 13 percent contained.
Based on this data, the Portland Water Bureau has developed an updated fire perimeter map. Please check this map periodically for updates on the fire perimeter in relation to the Bull Run Watershed.
As of Sept. 13, 2017, based on new infrared imagery data from very late Sept. 12, the fire has burned approximately 100 to 150 acres inside the Bull Run Watershed Management Unit, but not inside the actual Bull Run Watershed. Current estimates are that less than one percent of the Bull Run Watershed Management Unit has been burned at the northern edge.
Protecting the Bull Run remains a top priority of the fire response. The Bull Run reservoirs and water supply infrastructure are not near the areas that are currently estimated to have been burned.
Winds are currently dry and from west to east. Forecasts predict a half inch to two inches of rain starting Sunday night and into next week through Wednesday. Should these rains come as predicted, they could improve fire conditions, although the fire is expected to continue burning even if the forecasted rains occur.
The Water Bureau continues delivering 100 percent Bull Run water. The Water Bureau is continuing its monitoring and has not seen measurable impacts from the fire. The water continues to be safe to drink. Samples for additional monitoring have been collected to further investigate any effects of the fire on water quality. Results of this additional monitoring are expected back next week.
