Oxygen-depleted dead zones between dams in the upper Missouri River have been directly linked with the failure of endangered pallid sturgeon embryos to survive, according to a study. The study is the first to make a direct link among dam-induced changes in riverine sediment transport, the subsequent effects of those changes on reduced oxygen levels and the survival of an endangered species, the pallid sturgeon.
