(Salem, OR) -- Raw sewage flowed into the Willamette River at Salem on Wednesday. The City of Salem says a tide gate became stuck open due to solids that collected in the line and raw sewage flowed into the river at one gallon a minute, which is too slow to trigger an alarm. The problem was noticed during an inspection. 68-hundred gallons of raw sewage flowed into the river. The flow was stopped Wednesday morning.
