The City of Storm Lake bypassed approximately 250 gallons of sewage out of a manhole yesterday afternoon due to a plugged sewer. The sewage ran into a nearby storm sewer. Although the city vacuumed out a downstream manhole and flushed the line with water from a nearby fire hydrant, most of the wastewater reached Poor Farm Creek, a tributary to the Raccoon River, due to a connection with a second storm sewer line.
The City of Storm Lake and the Iowa DNR considered damming Poor Farm Creek, but the storm sewer outfall is mouth of the stream and fish were observed at that location. Damming the water would have resulted in dead fish. Areas downstream from the mouth had clear water, no odor, and live fish were observed at several locations.
At daybreak Sept. 26, the stream was checked by the Iowa DNR and no dead fish were discovered. Only live fish were observed. No further action will be taken.
