A chemical spill in a northern Iowa town has left a nearby creek polluted.

The DNR says 800 gallons of 28 percent liquid nitrogen fertilizer spilled at a Franklin County farm supply in Coulter around 5 p.m. on Monday.

According to the DNR the spill occurred as an employee of AG Vantage FS opened the wrong valve while filling a tanker. Though the spill was contained, about 650 gallons reached a tile inlet that drains into Maynes Creek, a drainage ditch on the south side of town.

Crews from the DNR inspected the stream Monday night and found five small dead fish. By 3:00 p.m. Tuesday the fertilizer had flowed about 5.5 miles downstream and no additional dead fish had been found, however field test kits showed ammonia levels in the water were still high enough to kill fish.

The DNR says it will continue to monitor the stream and the ongoing cleanup efforts.
