IA – Surface-applied manure from a Dubuque County dairy on a partially frozen
40-acre field west of Bernard resulted in runoff that killed more than 2,000
fish in an unnamed stream.
An Iowa Department of
Natural Resources investigation revealed that factors contributing to the
manure runoff were heavy rains, minimal corn stock residue, field slope,
inadequate separation distances, limited manure incorporation, and not checking
the area for recent drainage improvements.
