Willamina, OR – Heavy overnight rain triggered a major sewer overflow in Willamina late Thursday night, spilling more than 102,000 gallons of wastewater into Willamina Creek, according to city officials.
The incident occurred between 11:53 p.m. and 3:18 a.m. on December 18, 2025, when the E Street Pump Station became overwhelmed by the rapid rainfall. City officials said the auxiliary pump—normally used during high-flow events—was down for repairs at the time.
According to the City of Willamina, the overflow resulted in an estimated 102,928 gallons of sewage entering the creek. The Oregon Department of Environmental Quality (DEQ), Oregon Emergency Response System, and the City of Sheridan have been notified.
Residents are advised to avoid contact with Willamina Creek until water quality testing confirms safe conditions. Officials did not report any immediate impacts to drinking water systems but said cleanup and monitoring are ongoing.
The city said it is assessing the pump station’s repair timeline and reviewing emergency response protocols to prevent future incidents. Updates are expected as state environmental agencies complete their evaluations.
