Villafáfila lakes are natural lakes with electric conductivities between 4000-5000 µS/cm located in the valley of the Salado river. The piezometry of the area suggest that the hills surrounding the lakes are local recharge areas while the lakes and their surroundings around the lakes are discharge zones with low hydraulic gradient. Physico-chemical analyses of lake and groundwaters have allowed characterizing three hydrochemical facies: 1) calcium magnesium bicarbonate; 2) sodium chloride ; and 3) sodium bicarbonate-chloride waters. These hydrofacies record respectively, the local recharges of the surrounding hills, long and deep flow-paths discharging into the lakes, and a mix of the above. Villafálila lake waters are the result of a mixing of rain + runoff + local flows + regional deep flows + brine recycling. Sodium chloride waters could come from the dissolution of evaporites in the Cantabrian Mountains and/or from evaporites located in somewhere between these Mountains and the Villafáfila lakes.
