A recent Des Moines Register article by Perry Beeman gives a preview of the results of a three-year, Iowa State University/Iowa DNR study on the quality of Iowa lakes over time. The study, based on sediment samples taken from 33 of Iowa's lakes, reveals the dramatic changes in the lakes due to intensified agricultural land use.

The implications of the study may be far-reaching: Beeman writes, "The findings by Iowa State University scientist John Downing and colleagues are likely to figure heavily in future debates over farm regulations and the next Farm Bill."

Conservationists also hope that this information can help provide realistic goals for cleanup and restoration.
