The construction of dams is a contentious issue for some Native communities. The Garrison Dam in North Dakota, constructed in 1947, flooded one fourth of the Mandan, Hidatsa and Arikara Nation’s land base. In 2011, the Lower Elwah Klallam Tribe celebrated the removal of the dams on the Elwha River. A recent dam break in Brazil caused 11 deaths and another 12 people are missing. It also released over 60 million cubic meters of toxic mining waste into the Rio Dolce. The disaster affected several Indigenous communities including the Krenak tribe whose only source of drinking water is now contaminated. Should we take a second look at the dams in Native America?
