Rabat – Fueled by recent rainfall, Morocco’s water reserves continue to rise sharply. The country’s overall dam capacity stands at 46% as of January 12, representing a total of 7.716 billion cubic meters.
Morocco holds 61.8% more water than in 2025, adding nearly 2.95 billion cubic meters to its stock, thanks to rainfall across all major river basins.
The Bouregreg basin is currently one of the best supplied, with reservoirs nearly full at 94.9%. This level secures the water supply for the Rabat-Casablanca corridor, an area of high population and industrial demand.
The Loukkos basin shows a fill rate of 62.8%, with most dams reaching full capacity. The basin continues to play a central role in providing drinking water and supporting irrigated agriculture in the region.
The Sebou basin holds more than 3 billion cubic meters, at 54.8% of its capacity, confirming its position as the country’s main water reservoir. Its ample reserves remain crucial for both urban centers and agricultural zones.
Tensift’s dams reached 71.3%, with significant improvements in the Al Haouz area, long affected by water shortages.
In the Guir-Ziz-Rhéris basin, the fill rate rises to 56.9%, largely due to the Hassan Addakhil dam. For the Southeast, these reserves offer essential support in a region prone to arid conditions.
Moulouya’s reservoirs stand at 37.6%, reflecting uneven recovery. Some dams benefited from rainfall, but the basin overall remains vulnerable, depending on further precipitation to reach safer levels.
Souss-Massa shows a fill rate of 49.4%. While some dams are well supplied, high agricultural and urban demand continues to strain the basin’s resources.
The Oum Er-Rbia basin remains fragile, with reservoirs at just 20.8%, and major dams such as Al Massira at 8%. In Drâa-Oued Noun, the fill rate reached 29.8%, reflecting only modest improvement in an arid climate with irregular rainfall.
Experts warn that despite the recent boost, the country cannot rely solely on current rainfall.
Sustained water management and continued precipitation remain essential to balance Morocco’s water needs in the face of climate variability and growing demand.
