A number of fish have been killed in a creek which stretches across the Iowa/Minnesota border. Iowa officials say fertilizer from an elevator in Myrtle, Minnesota, is to blame for killing fish in Deer Creek. About three-and-a-half miles of the stream were affected. There’s a smallmouth bass fishery at the end of Deer Creek, but officials don’t believe the fertilizer reached the fishery. An estimated 800 gallons of fertilizer got in a tile line which drained into the creek. Darters, minoows, suckers and chubs are floating, dead, in the creek bed.
