Anotace knihy

Despite our enormous environmental problems and the pollution of most of our rivers, there have been very few longitudinal studies of any of our major rivers. Jim Gammon has worked on the Wabash River for 30 years, monitoring its general quality as demonstrated through the populations of the River's many species of fish. The study focuses on a 160-mile stretch of the river between Delphi and Merom, Indiana. Judgments are made about the nature of pollutants and their impact, especially agricultural runoff. Perhaps the most important finding is that reductions in pollutants reaching the river have a fairly immediate effect on the size and health of fish populations.
