A conservation lens
River fish depend on connected water. Dams, blocked migrations, pollution, and altered flow can matter even when the channel still looks wet.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
