Dams have major downstream effects in settings throughout the United States.
These effects depend on the operating regime of the dam, the extent of flood control, the amount of sediment deprivation downstream, and the nature of riverine and aquatic ecosystems in the river. This publication provides an overview of the effects of six dams on the downstream environment, written in a style for lay audiences. The human factor in mining reclamation, by B. F. Arbogast, D. H. Knepper, Jr. and W. H. Langer. This report both describes mine sites with serious problems and draws attention to thoughtful reclamation projects for better future management. It presents information from selected sites in terms of their history, landform, design approach, and visual discernment.
