Water reserves stored in Morocco’s dams have reached 11.43 billion cubic meters, while the national filling rate rose to 67.15%, nearly double the level recorded during the same period last year.

According to updated data from the General Directorate for Water Research and Planning, the national dam filling rate stood at 67.15%, compared with 33.51% during the same period in 2025. Total stored reserves currently amount to 11.43 billion cubic meters, out of a normal overall storage capacity of 17.02 billion cubic meters. During the same period last year, reserves did not exceed 5.7 billion cubic meters. This improvement represents an important factor in strengthening Morocco’s water security, supporting agricultural activity, ensuring drinking-water supplies and meeting the needs of certain industrial activities.

Major Differences Between River Basins

The Sebou, Loukkos, Tensift and Bouregreg basins are all recording filling rates above 78%. Sebou has reached 80.14%, Loukkos 79.18%, Tensift 78.85%, while Bouregreg stands at 78.84%. The Oum Er-Rbia basin has also recorded a significant improvement, rising from just 10.07% in 2025 to 59.16% in 2026. By contrast, the Draa-Oued Noun basin remains at 32.33%, while the Ziz-Guir-Ghris basin stands at 39.28%.

These figures significantly improve Morocco’s national water-security outlook. However, persistent disparities between the different basins remain a major challenge for agricultural and industrial investment planning and for the distribution of water resources.
