The reservoir was built in 1955 in order to produce hydroelectric power and is located at the foot of the N-230, where this road enters El Pont de Suert (L'Alta Ribagorça). The Escales reservoir, is the largest and most emblematic reservoir in the comarca (local district) and provides a supply of crystal-clear water as well as offering rocky nooks and waters that are ideal for all types of water sports and aquatic games and activities, including fishing, water skiing and canoeing.

The reservoir is headed by an imposing dam, next to which there are a series of steps carved out of the rock. At the other end of the reservoir, at the foot of the N-260, heading towards La Pobla de Segur, it is possible to see the ruins of the Cistercian monastery of Lavaix.
