SEATTLE — King County reports an estimated 8 million gallons of raw sewage poured into Ravenna Creek after county crews mistakenly diverted it into a Seattle storm drain.
County Wastewater Treatment Division spokeswoman Annie Kolb-Nelson says the sewage has overflowed at a rate of 800,000 gallons a day for 10 days. She says it likely went into Union Bay.
The affected area is on the University of Washington campus and near a boathouse and parking lot.
Kolb-Nelson said Saturday crews stopped the flow of sewage into the creek on Friday after discovering the problem.
The area most affected by the spill is a one-mile stretch of the creek from Northeast 45th Street near Mountlake Boulevard to the Union Bay Slough.
County officials have closed the affected area to swimmers, waders and people walking their dogs. They could keep it closed for up to three days.
