The Connected Consequences of River Dams

In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another.

“We have known for a long time that dams have dramatic effects on river form and function,” said Jerad Bales, acting USGS Associate Director for Water. “In the past, however, the effects of dams generally have been studied individually, with relatively little attention paid to how the effects could interact along a river corridor.” (more…)
