There is no ibon, it doesn't match the photos. It's just a pond for the animals to drink from.

The waters of the Arga river were retained by means of a damming in 1973, to supply water to the population of Pamplona and its region. The landscape of the town of Eugi changed forever, since the forestry house, the oven, the bakery and the mill of the town were left under the waters of the swamp.
