Mdez Dam “breathes again”… 2026 rains boost its storage and revive hopes for the Sebou Basin

Consistent sources report that Mdez Dam has recorded a notable improvement in its water storage at the start of 2026, benefiting from rainfall across the Sebou Basin in recent weeks, with the filling rate reaching about 20% of its total capacity, estimated at nearly 700 million cubic meters.

L’importance stratégique de cette hausse du stock réside, selon les données disponibles, dans le renforcement de la prévention contre les risques d’inondation dans les zones avoisinantes, ainsi que dans le lancement de la sécurisation des ressources hydriques liées au projet de transfert d’eau vers la plaine de Saïs Plain, destiné à réduire la pression croissante sur la nappe phréatique de la région.

The strategic significance of this rise in storage, according to available data, lies in strengthening flood-risk prevention in surrounding areas, as well as initiating the securing of water resources linked to the water transfer project toward the Saïs Plain, aimed at easing the increasing pressure on the region’s groundwater table.

Ces indicateurs positifs s’inscrivent dans un contexte global relativement rassurant au niveau du bassin du Sebou, les données actualisées montrant que the overall filling rate of the basin’s dams has exceeded 68%, which is expected to support stable drinking-water supply and secure irrigation needs for the current agricultural season.

These positive indicators fall within a generally reassuring context for the Sebou Basin, with updated data showing that the overall filling rate of the basin’s dams has exceeded 68%, which should support stable drinking-water supply and meet irrigation needs during the current agricultural season.
