Ebro

With a length of 578 miles, the Ebro is the longest river located entirely in Spain and the second-longest in the Iberian Peninsula. The Fontibre springs in northern Spain are its source. The river's drainage basin spans 33,000 square miles or almost a sixth of Spain's total geographical area. The Ebro is a river that travels eastward and empties into the Mediterranean Sea. The Ebro is fed by about 200 tributaries. The Gallego and Aragon Rivers are two of the most important tributaries.

The Ebro is a river that supports hydroelectric power plants that provide electricity to Spain. Vineyards are also irrigated by the river. There are 95 bird species, 69 animal species, and nine plant species in the Ebro basin. The Ebro's fish contain significant levels of mercury, and the European Union forbids commercial fishing on the river. Dam development, chemical pollution from industry, the introduction of alien plants and animals, and agricultural dumping are all threats to the Ebro eco-system. The Ebro Delta National Park was established in 1986 to protect Ebro's unique ecosystem.
