Short summary
Dams impact river reaches. Upstream of dams, reservoirs transform terrestrial organic carbon and produce autochthonously derived organic carbon. In addition, tailwater reaches below dams may produce and export similar amounts of organic carbon to that stored behind dams. Our work demonstrates that not only do reservoirs need to be considered for their capacity to store and transform organic carbon but also the combined impact of their tailwater ecosystems should to be considered as well.
