A mixed status of water resources
New figures published for November 24, 2025, confirm a persistent trend: the situation of Moroccan dams remains fragile. The national rate stands at 31.2%, corresponding to a total volume of approximately 5,229 million m³. This level is significantly lower than historical averages and is accompanied by strong disparities among hydraulic basins.
The Oum Er-Rbia basin remains one of the most concerning, with only 8.8% filling. Several strategic structures, such as Timnoutine, Aït Messaoud, or Douarate, show very low rates, some below 15%. This situation directly affects the water supply to agricultural and industrial areas in the region, increasing pressure on the water table.
In contrast, the Bouregreg basin presents a much more reassuring situation. With 64.5%, it is one of the few areas where reserves exceed half of the total capacity. The Sidi Mohamed Ben Abdellah dam accounts for a significant portion of the volume, confirming its central role in supplying water to the regions of Rabat and Casablanca.
The Loukkos basin also shows acceptable levels, reaching 45.5%. Several dams such as Chefchaouen, Charif Idrissi, and Oued El Makhazine exhibit rates above 70%, indicating better water replenishment in the northern part of the country and relatively favorable rainfall in recent months.
The Sebou and Moulouya basins are in an intermediate zone. The Sebou reaches 40.3%, driven by the Allal El Fassi and Garde Sebou dams, while the Moulouya remains stagnant at 27%, revealing increased pressure on water infrastructure in the Oriental region.
In the south of the Kingdom, the figures confirm a more tense situation. Souss-Massa records only 19.2%, with structures such as Abdelmoumen, Youssef Ben Tachfine, or Imi El Kheng exhibiting particularly low rates. The Draa-Oued Noun basin remains at 28.1%, a level insufficient to ensure sustainable coverage of agricultural and domestic needs.
The Guir-Ziz-Rheris basin reaches 47.1%, driven by the Hassan Addakhil dam. The Tansift stands at 42.9%, providing relative stability but remaining dependent on future precipitation.
These discrepancies highlight the urgency for differentiated regional management, based on anticipation and resource diversification. Between surplus basins and areas in severe water stress, the Kingdom must continue its efforts in desalination, reuse of treated wastewater, and consumption rationalization.
The winter period will be crucial. Precipitation in the coming weeks could relieve tensions in some basins, but projections remain uncertain. In the meantime, the published figures paint a clear picture: Morocco must navigate between vigilance and strategic planning to secure its water resources.
