At the confluence of the Segre and Ebro rivers, the Aiguabarreig Ebro-Segre-Cinca is a space with great natural wealth and a great variety of ecosystems that range from Mediterranean steppes to impenetrable riverside forests, making this space a paradise for biodiversity. Territorially, the Aiguabarreig is at the centre of the Middle Depression of the Ebro. It borders to the west with the Monegros, to the east with the Tossals de Montmeneu and Almatret and to the south with the tail of the Ribarroja reservoir. This space is named with Catalan word of origin that designates the place where two or more water streams meet and form one. The Segre and Cinca form a first Aiguabarreig between the towns of La Granja d’Escarp, Massalcoreig and Torrente de Cinca, a few kilometres downstream they converge with the waters of the Ebro, already in the municipality of Mequinenza, forming one of the largest river confluences of the entire Iberian Peninsula.
