Dam removal
Dam removal is the process of removing out-dated, dangerous, or ecologically damaging dams from river systems. There are thousands of out-dated dams in the United States that were built in the 18th and 19th centuries, as well as many more recent ones that have caused such great ecological damage, that they are proposed for removal.Catastrophic dam failures such the 1977 Kelly Barnes Dam, killing 39 students, faculty and staff of the college, the 1976 Teton Dam failure in Idaho, the 1928 St. Francis Dam failure in California, and the 1889 Johnstown Flood remind people of the dangers dams can present. The largest catastrophic failure of a dam was the 1975 Banqiao Dam disaster that killed 26,000 people immediately, resulted in 145,000 dying of disease later, and displacing 11,000,000 residents.In 2014 the film DamNation was released illustrating and advocating the strategy of dam removal.
