After heavy rainfall, Morocco’s dam reservoirs stood at 7.586 billion cubic meters, on Thursday, January 8, 2026, representing 45.2% of total capacity. This represents a sharp rise from 4.7 billion cubic meters (28.39%) recorded on the same date last year.
Within four weeks, from December 14 to early January 2026, Morocco’s dams captured 2.3 billion cubic meters of water, equal to 14.2% of national storage capacity—a figure that underscores the exceptional scale of this rainy episode.
As a direct result of these inflows, several dams have now reached full capacity. Leading the list is the Sidi Mohammed Ben Abdellah dam, strategic for the Rabat–Casablanca axis, currently storing 967 million cubic meters (Mm³), followed by the Oued El Makhazine dam with 672 Mm³.
Other medium‑sized reservoirs have also reached full capacity, including Chérif Al Idrissi (121 Mm³), Allal El Fassi (99 Mm³), and the Oued Za dam (94 Mm³). The Moulay Abdellah and Aoulouz reservoirs respectively hold 90 and 88 Mm³.
In addition, small reservoirs with capacities not exceeding 10 million cubic meters (Ahl Souss, Nakhla, Timoutine, Sidi Idriss…) have reached full capacity.
On the other hand, the situation of major dams is gradually improving. Al Wahda now exceeds 57% of its total capacity, surpassing 2 billion cubic meter mark. Meanwhile, Al Massira dam has surpassed, for the first time in several years, the threshold of 200 million cubic meters. Yet despite this progress, its reserves remain limited at just 8% of capacity.
Satellite data illustrate the significant evolution of dam filling levels across the country between December 2025 and January 2026.
