DNR Investigating Fish Kill, Likely Manure Spill in Dry Branch Creek
Preliminary water tests found ammonia, and crews reported cloudy water and a strong manure smell as investigators seek the source.
- On Thursday, the Iowa DNR began investigating a fish kill in Dry Branch Creek near Ossian after receiving reports of dead fish, murky water, and a "strong smell of manure" in southern Winneshiek County.
- Initial water samples tested positive for ammonia, and staff observed "cloudy" conditions in the creek south of 110th Street, according to officials working to determine the contamination source.
- Investigators found the fish kill extends nearly three miles downstream into Fayette County as the creek exits Winneshiek County, revealing the broader scope of the contamination.
- The Iowa DNR has notified Fisheries staff and advises downstream users to avoid using water from Dry Branch Creek while the investigation continues to identify the pollution source.
- Dry Branch Creek has experienced three previous fish kills linked to fertilizer or animal waste, including one in 2021 that resulted in an $18,000 fine; the DNR encourages reporting distressed fish via the 24-hour spill line.
