Morocco’s largest and Africa’s third biggest dam of Al Wahda has reached near-capacity levels following months of heavy rainfall, offering a major boost to the country’s water reserves while highlighting the impact of unusually abundant precipitation that has also triggered flooding in several regions.
As of May 31, the Al Wahda dam, located in Ouezzane province, was filled to 88.7% of its capacity, holding more than 3 billion cubic meters of water, according to official data from the Ministry of Equipment and Water.
The dam is now close to its maximum storage capacity of 3.8 billion cubic meters.
The rise marks a sharp increase compared to the same period last year, when the reservoir stood at just over 58%, reflecting a strong recovery after a period of water stress that saw levels fall to around 42% in September 2025.
Beyond water storage, Al Wahda serves as a critical buffer against floods in the Gharb plain and surrounding regions, helping regulate river flows during peak inflow periods.
The high fill rate is expected to strengthen Morocco’s water security heading into the summer, ensuring stable supplies for drinking water, agriculture and hydroelectric production.
