For the second time in about two weeks, the city of Gladstone experienced a raw sewage overflow into the Clackamas River.
It happened Thursday at the south end of Portland Avenue, near the confluence of the Clackamas and Willamette rivers.
City workers said the overflow is the result of excessive rain overloading an intersection point of the city's wastewater and storm water systems.
The same situation happened back on Dec. 5.
People in the area are asked to avoid contact with the rivers for two days because of the bacteria associated with a raw sewage overflow.
