PORTLAND, Ore. (KOIN) — A sewage overflow in Southwest Portland has impacted Fanno Creek. City officials have advised the public not to have any contact with the creek for the next two days due to the bacteria in the water.

The Portland Bureau of Environmental Services said the sewage came from a manhole on a residential property on SW Bertha Boulevard near SW 27th Avenue Monday. The overflow contaminated a tributary of Fanno Creek.
