The Source of the Queiles River

Nature · Vozmediano, Moncayo, Soria

The Queiles river rises in Vozmediano (Soria), where the water gushes forth from a chasm at the foot of the Moncayo, at an altitude of 920 metres; this spring is the second most abundant in Europe, with an average flow of one thousand five hundred litres per second. Downstream it receives the río del Val or Cailes, which rises in Ólvega and irrigates Ágreda, forms notable escarpments in the conglomerates of Tarazona and, after that town, widens its course to irrigate an area of close to 10,000 hectares. The Queiles is regulated by the Val reservoir, one of the most affected by eutrophication in the Ebro basin due to discharges from the Ágreda-Ólvega treatment plant. It then crosses Aragon and Navarre, running 44 kilometres before flowing into the Ebro at Tudela.
