Vouga River

The Vouga River is a river in Portugal's Centro Region. Chafariz da Lapa, at an elevation of 864 meters (2,835 feet), in the parish of Quintela, municipality of Sernancelhe, Viseu District, is the source of the Vouga. The river's path culminates in a ria, the Ria de Aveiro, in the Atlantic Ocean. With an area of approximately 106,460,000 km2, the Atlantic Ocean is the world's second-largest of the five oceans (41,100,000 sq mi). It covers about 20% of the Earth's surface and about 29% of its water surface area. In the European perception of the World, it is known to separate the "Old World" of Africa, Europe, and Asia from the "New World" of the Americas.

On the Vouga River, there are four tributaries:

• Águeda (left bank)
• Caima (right bank)
• Sul (right bank)
• Teixeira (right bank)

Cacia pulp and paper mill effluent is discharged into the Aveiro coastal area, making it one of the most polluting sources of the Vouga River and Aveiro Lagoon. Because of the wastewater, the area has an awful odor.
