The reservoir has a surface of maximum level of 42.5 hectares in its maximum level and a capacity of 5.3 hm3.
It belongs to the “Comunitat de Regants de Riudecanyes” (local community that holds the right to use the water in the Reservoir of Riudecanyes) and most of the water kept in it comes from the wash of Riudecanyes which at the same time, comes from the hydrographic system of Siurana. Currently, the water in the Reservoir is used for watering the lands in the area as well as to offer water supply to different towns.
The area where it is located is a unique area in the pre-littoral mountain chain which shows a beautiful and surprising landscape, especially for tourists who visit the beach and find this green and mountain landscape unexpectedly.
The surroundings have different aesthetic, ecological, productive and historical values which are really important such as: Serres de Pradell- Argentera, a Site of Nature Conservation Interest; fields of olives and hazelnut trees; the Castle and Mountain in Escornalbou, etc.
