Morocco’s Dam Reservoirs Rebound to 66.3% Following Recent Heavy Rainfall

Recent rainfall across several regions of Morocco has driven a major recovery in the nation’s hydrological reserves. According to official data as of October 26, 2026, the overall filling rate of Moroccan dams reached 66.3%, up significantly from 31.5% during the same period last year—a 34.8 percentage point increase. Total stored water volume jumped by approximately 113% year-on-year to reach 11.2 billion cubic meters.

Despite the strong national average, noticeable disparities remain between different hydraulic basins:

Sebou & Bouregreg Basins: Leading the recovery with filling rates of 75.6% (4.06 billion m³) and 77.3% (1.14 billion m³), respectively. Major facilities such as Al Wahda (78%), Sidi Mohammed Ben Abdellah (70%), and Tiddas (91%) recorded strong storage levels.

Loukkos, Tensift & Moulouya: The Loukkos basin in the north stands at 73.6% (1.44 billion m³), Tensift reached 74.2%, and Moulouya climbed to 72.6% (509.4 million m³), supported by several dams operating near or at full capacity.

Oum Er-Rbia Basin: Reached an overall rate of 58.9% (2.95 billion m³). Key reservoirs like Bin El Ouidane (80%) and Ahmed El Hansali (78%) saw sharp gains, although the Al Massira dam remains at a more moderate level of 40%.

Southern Basins: Regions in the south and south-east lag behind the national trend. Guir-Ziz-Gheris stands at 56.3%, Souss-Massa reached 46.8% (despite high levels in smaller dams like Dkhila at 94%), while Drâa-Oued Noun recorded the lowest overall rate in the country at 38% (398.6 million m³).
