Morocco’s dam reserves have more than doubled over the past year, reaching a filling rate of 66.19% on November 13, compared with 30.79% on the same date in 2025, according to the Ministry of Equipment and Water.
Reservoirs held 11.27 billion cubic metres of water, out of a combined capacity of 17.03 billion cubic metres, marking a 35.4-percentage-point increase after years of drought.
All nine river basins covered by the latest data recorded improvements, although water availability remains uneven across the country.
Five basins exceeded 70% capacity, with the Tensift approaching 80%, while four remained below 60%. The Drâa-Oued Noun basin continued to face the greatest pressure, with reserves below 40%.
The Sebou basin accounted for more than a third of Morocco’s stored water, holding 3.96 billion cubic metres at a filling rate of 73.81%, compared with 41.63% a year earlier.
Within the basin, Al Wahda dam held nearly 2.60 billion cubic metres, reaching 75.22% capacity, while Idriss I stood at 71.63%, with 770.18 million cubic metres.
Several smaller reservoirs reported considerably higher levels, including Allal El Fassi at 95.38%, Sahla at 89.57% and El Kansera at 88.31%.
