Water Storage in Tunisian Dams: A Mixed Bag
The total volume of hydraulic inputs in Tunisian dams reached 902.6 million m³ between September 1, 2024, and May 15, 2025, marking a 21% increase compared to the same period last year (794.3 million m³). However, this figure remains lower than the average of the last three years, which stands at 1,682.1 million m³, recording a 46.3% compared to this average.
The total volume of water stored in Tunisian dams currently stands at 964.8 million m³, representing a filling rate of 40.7%. These resources remain largely concentrated in the north of the country, which holds 90.9% of the stock, while the center and Cap Bon record 7.1% and 2%, respectively.
The dams of Sidi Salem and Sidi el Barrak display particularly low filling rates of 35.5% and 69.5%, respectively. These figures confirm the persistent fragility of the water situation in Tunisia, despite the slight improvement observed this year.
The geographical distribution of inputs also remains unbalanced, with 90.4% of inputs located in the north, 7.1% in the center, and 2.5% in Cap Bon.
