Iowa DNR investigates second Lyon County fish kill

Posted: Updated:
LYON COUNTY (KWWL) -

Iowa Department of Natural Resources officials say aerial spraying has killed more fish and crawdads in Lyon County.

A DNR conservation officer reported seeing dead fish and crawdads of different sizes and species in a stream in Lyon County.

Staff took field tests of water samples, and the results ruled out excessive manure and fertilizer as causes of the kill.

Aerial spraying is the most probable cause of the kill, pending lab results, according to DNR officials.

This is the second recent Lyon County fish kill likely due to aerial spraying.

Officials warn that some pesticides, even in small amounts can be toxic to fish and other aquatic organisms. .

The stream flows into Rat Creek, a tributary of Otter Creek located between Ashton and George in the eastern part of the county.

Report fish kills to the DNR's 24-hour spill line at 515-281-8694, or to the regional DNR field office during business hours at www.iowadnr.gov/InsideDNR/DNRStaffOffices/EnvironmentalFieldOffices.aspx
