Eutrophic means: Pertaining to a lake containing a high concentration of dissolved nutrients; often shallow, with periods of oxygen deficiency. Difficult for fish and other organism to survive.

No, not all eutrophicated rivers recover.

* They will recover if the source of the nutrients is removed, for example, if farmers stop using large amounts of chemical fertilizer that is washed off the land and into waterways. * They will recover if there is rainfall in their catchment areas upstream and fresh clean water is added to the river.
