Morocco’s water reserves have recorded a significant improvement, with the national dam filling rate reaching 66.27% as of Sunday, November 15, according to official data from the Ministry of Equipment and Water.
The stored water volume stood at approximately 11.28 billion cubic meters, out of a total normal capacity of 17.03 billion cubic meters.
The improvement is particularly pronounced compared with the same period last year, when the national filling rate stood at just 31.03% on November 15, 2025. The volume of stored water has therefore more than doubled year on year.
Tensift basin leads regional rankings
Among Morocco’s main river basins, Tensift recorded the highest filling rate at 80.37%, followed by Bouregreg at 76.53% and Sebou at 73.84%.
Moulouya reached 72.45%, while Loukkos stood at 72.20%.
Other basins recorded more moderate levels, including Ziz-Ghris at 59.79% and Oum Er-Rbia at 59.60%.
Further south, the filling rate reached 53.02% in the Souss-Massa basin and 39.51% in the Drâa-Oued Noun basin.
Major dams record varying water levels
The country’s largest reservoirs also recorded differing filling rates.
Al Wahda Dam, located in the Sebou basin and the largest in Morocco, reached 74.98%, with stored water estimated at 2,588.48 million cubic meters.
Al Massira Dam, the country’s second-largest reservoir and part of the Oum Er-Rbia basin, stood at 41.87%, holding approximately 1,109.40 million cubic meters.
Other strategic dams recorded relatively high levels, including Bin El Ouidane at 78.69%, Idriss I at 71.68% and Sidi Mohammed Ben Abdellah, in the Bouregreg basin, at 71.78%.
Daily reservoir data showed that only one dam had reached full capacity, with a filling rate of 100%. The dam, located on Oued Za in the Moulouya basin, has a normal storage capacity of 87.92 million cubic meters.
By comparison, several dams had reached full capacity on the same date last year, including Allal El Fassi, M’Jara Sebou, Sidi Driss and Aït Messaoud. None had reached that level this year, despite the substantial increase in the country’s overall water reserves.
