Water and rivers

With a surface area of over 10,400 km2, Navarra encompasses a great variety of landscapes, ranging from the driest to the wettest, and very diverse geological formations and very marked relief, with periods of water shortage and others with plenty of water and floods. Leer más

 On the other hand, there is also an imbalance existing in this region between demographic occupation and the availability of water resources.

The geography of Navarra is marked by its rivers. There are nearly 7,500 kilometres of watercourse in total. Practically the entire territory covered by the region links up around the tributaries of the Ebro. Almost all the towns in Navarra are located on the banks of the Arga, Ega and Aragón rivers. In the north, the Bidasoa is the river that links up a major part of the territory.

The total contribution of the river network in Navarre amounts to 5,000 Hm3, which enables it to meet its needs. However, water is distributed unevenly. The mountains, in addition to maintaining the completeness of the water systems, also supply clean water to the rest of the territory, which is in especially short supply on the right bank  of the Ebro River  (Queiles and Alhama).

Aquifers in Navarra are grouped together into 11 hydrogeological units. From the water available, 1,235 hm3/year will end up as underground water – approximately 25% of the region’s own total resources.
