... the characterization of trophic status in rivers is known to be more challenging than for lakes (Dodds 2006 , Dodds and Smith 2016 ), there is little debate among ecologists that ecosystems tend to degrade as they become more eutrophic (Smith 2003 ). However, how this degradation impinges on the safe delivery...
