Agadir – Recent rainfall has significantly boosted Morocco’s national water reserves, with dams across the kingdom accumulating 246 million cubic meters (Mm³) of water in just 24 hours. The overall filling rate rose from 42.5% to 43.9% between January 5 and 6, 2026, according to official figures.
The increase highlights the immediate effect of rainfall on surface water resources, particularly in a country grappling with climate variability and recurring water stress in recent years.
The total volume of water stored in Morocco’s dams rose from 7,123 Mm³ to 7,369 Mm³, demonstrating the reservoir system’s capacity to respond quickly when multiple watersheds are replenished simultaneously.
In just 24 hours, the total volume of water stored in Morocco’s dams rose from 7,123 Mm³ to 7,369 Mm³, a gain of 246 Mm³. The average filling rate increased from 42.5% to 43.9%, demonstrating the reservoir system’s ability to respond quickly when rainfall affects multiple watersheds simultaneously.
The national dam performance varies across Morocco:
- Al Wahda, the country’s largest dam, saw its filling rate rise from 54% to 55%, adding an estimated 51 Mm³.
- Ahmed El Hansali increased from 34% to 38%, gaining 25.5 Mm³.
- Bin El Ouidane improved from 18% to 20%, a 25.3 Mm³ increase.
- Sidi Med Ben Abdellah approached maximum capacity, from 98% to 99%.
- Oued El Makhazine reached full capacity on January 6, compared with 98% the previous day.
- Idriss I stabilized around 41%, showing a slight increase in stored volumes.
