The United States is likely to see a continuation of the recent dam removal trend. An emerging need is to provide relevant scientific information about the physical, biological, and ecological responses of rivers and reservoirs to dam removal. Retaining specific details about removed dams will provide valuable information to those researching and making decisions on future dam removals. USGS has been tracking dam removal across the country. The interactive tool at this link allows you to zoom in to a particular site and scroll over for detailed information on the dam that was removed.
