The Marcal is a right tributary of the Rába which has its source 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.
In October 2010, the Marcal was contaminated in a chemical spill by red mud and suffered complete loss of aquatic life.[1]
