Cause listed as "Split hose during land application of manure".

ESD FO2 was contacted by local residents and Primrose Facility about a manure spill and dead fish in anunnamed tributary to the Little Cedar River on Thursday evening, April 23. ESD FO 2, Mason City, contacted FisheriesFriday morning, April 24 about the fish kill and investigating ESD field crew. Fisheriesbegan the investigation at the downstream berm, about 384 yds. below a culvert on 450 th St. Staff counted andmeasured all dead fish over a 0.49 mi distance until no dead fish were found and live fish were seen. Farmers were workingfields, land applying manure and anhydrous ammonia.

Water clarity was good except when berm containing manure was allowed to break. As water levels dropped, loose materialstirred up making water turbid and fish counts at start difficult. Fish were also hard to see on stream bottom if covered toodeeply by manure or other material. Species identifications were possible for all fish carcasses. We identified the followingspecies in the kill extent: Bluegill, Creek Chub, Fantail and Johnny Darter, Blacknose and Southern Redbelly Dace, FatheadMinnow, White Sucker, stonerollers, and stickleback
