Marcal
The Marcal is a right tributary of the Rába which rises near Sümeg in the Bakony region of western Hungary. The river flows north and reaches Ukk on the Little Hungarian Plain. It follows a path similar to the Rába, and in many places the two rivers are only a kilometer apart. The two rivers meet at Győr.Other
In October 2010, the Marcal was contaminated in a chemical spill by red mud and temporarily suffered massive loss of aquatic life from which it has since recovered.
