The Grand Canyon is heralded as one of the wildest and iconic landscapes found on our planet. Yet, this seemingly untouched and natural wonder has been shaped by more than just the mighty Colorado River itself. The installment of hydropower dams have drastically altered the river and subsequently, the entire ecosystem that depends upon it. A recent wave of research has documented how river flows released from these dam operations are actually depleting this ecosystem’s base of the essential prey for fish, birds, reptiles, amphibians, and other predators. Not only do these findings hold pivotal implications for how to more efficiently manage dam-controlled rivers, but in addition, it has all been driven by the hands and minds of citizen science.
