The City of Salem announced that an overflow of untreated sewage occurred into Gibson Creek on February 10, 2025, at approximately 7:15 pm near 3421 Wallace Rd NW.

Approximately 3,550 gallons of untreated sewage were spilled.
Signs are being placed to warn residents to avoid water contact in Gibson Creek east of Wallace Road towards the Willamette River due to potentially high levels of bacteria.
