Iowa DNR traces fish kill to 2 feedlots

DOON, Iowa (AP) — Officials say a preliminary investigation into a fish kill in northwest Iowa indicates manure runoff from two feedlots is to blame.

The state Department of Natural Resources says manure-laden runoff went into the Little Rock River east of Doon in Lyon County at some point during the Labor Day weekend. A citizen on Monday reported the fish kill, which spanned along a two-mile section of stream.

The dead fish included smallmouth bass and channel catfish, along with carp, suckers, largemouth bass, gar, chubs and minnows.

Environmental specialists traced the high levels of ammonia, odor and color to two open feedlots near Doon that raise beef cattle. Officials say about two inches of rain fell in the area Saturday night.

Specialists are conducting a fish count Tuesday.
