Yesa Reservoir

About

The Yesa Reservoir is located in the Pyrenees, and is formed with the damming of the Aragon River, in the Navarre town of Yesa (Spain), although the largest area of the reservoir is located in the province of Zaragoza, extending from east to west. It is located to the northwest of the Aragonese province of Zaragoza and to the east of Navarre. Most of it floods lands of the Berdun Canal, in the Aragonese region of Jacetania in the municipalities of Sigüés, Ruesta, Escó, and Tiermas. It is known by the nickname Mar de los Pirineos (English: sea of the Pyrenees) and is located at the entrance of the aforementioned. It is the largest navigable area of Aragon and it is the source of the Bardenas Canal that transfers water to the Ribera area south of Navarra and irrigates the Bardenas Reales and the Cinco Villas region of Zaragoza. It is also used for water supply and as a power station. It has a capacity of 446.86 hm³ (although it has held 488.10 hm³), reaching the following elevations: minimum, 435.00 m; crest, 490.00 m; spillway, 482.61 m and maximum normal reservoir elevation of 488.61 m. The length of the tail end of the reservoir is 10 km with widths varying between 1 and 2.5 km. It occupies an area of 1900 hectares. It was inaugurated in 1960 and caused the abandonment of several towns: Ruesta, Tiermas, and Escó with an affected population of more than 1500 people. Collaterall
