The bank of a creek in Creston, IA collapsed and severed a sewer line on Tuesday, which spilled untreated wastewater into the creek for about four hours until city workers were able to repair it, according to the Iowa Department of Natural Resources.

According to State Records, Hurley Creek goes through much of the north and west sides of town, and there have been restoration efforts to stabilize the banks. A shift of the soil likely caused the cast-iron pipe to come apart, said Dan Olson, a senior environmental specialist for the DNR. 

The wastewater leak in the creek happened Tuesday about a mile upstream of the McKinley Lake, which was created about 150 years ago by damming the creek, the DNR reported. The lake is a public attraction for a zoo with bears, elk, wolves and exotic birds, among other creatures.

Originally, the pipe was constructed under the creek bed, but it had been exposed by erosion over the years, he said. About five gallons of sewage was flowing into the creek each minute.

An estimated 1,275 gallons of sewage leaked into the creek, which Olson doubted would have much of an impact on the McKinley Lake.
