The Iowa Department of Natural Resources is investigating a fish kill at the South Branch of Lizard Creek in Fort Dodge.
On April 14, the DNR Field Office in Mason City received a call from CJ Bio America in Fort Dodge regarding a leak at their facility. A fertilizer byproduct created in the process of making lysine had emptied into a stormwater channel on the east side of the plant.
Plant staff believed the byproduct was contained, but later discovered a breach in the berm of the storm water channel. An unknown amount of the byproduct flowed from the breach into surface intakes in an adjacent field, which outlets to the South Branch of Lizard Creek.
DNR field staff responded to the incident, and upon arrival observed the byproduct in the South Branch of Lizard Creek several miles downstream from the plant. Dead fish were also observed in the creek for several miles.
The leak has been stopped, however due to flow and access restrictions, placing berms in the creek is not an option at this time. Water samples have been collected, and the investigation is ongoing. Downstream users are advised to stay out of the creek at this time. DNR
