National water storage in Morocco reached 65.95% of total capacity on October 19, according to figures released by the Ministry of Equipment and Water and reported by Hespress English. This level represents a daily increase of nearly 50 million cubic meters, moving the national figure up by 0.29 percentage points from the previous day. The growth was linked to severe weather systems, including hail, that impacted various regions across the country.
The single-day gain surpassed the total accumulation recorded during the first half of October, which amounted to roughly 43.7 million cubic meters. While the current storage is more than double the 31.89% recorded on the same date in 2025, it remains slightly below the peak of 66.02% achieved on September 24. Hespress English calculated that the October 19 total was approximately 30.7 million cubic meters higher than the level observed on October 12.
The Ziz-Ghris-Ker basin experienced the most significant daily surge, adding 23.69 million cubic meters to its reserves. This increase was primarily driven by inflows at the Hassan Addakhil and Kaddoussa dams. The Moulouya basin also saw a substantial rise of 11.55 million cubic meters, while the Oum Er-Rbia and Draa-Oued Noun basins recorded smaller but notable gains. These changes aligned with heavy precipitation in the southeast, where Boudnib logged 60 millimeters of rain.
Conversely, several northern basins saw their filling rates dip slightly despite local rainfall. The Loukkos basin, for example, dropped to 74.37% even after receiving 50 millimeters of precipitation in Souk Lqolla. Hespress English noted that rainfall in a specific location does not always translate to an immediate rise in the reservoirs serving that basin, as the two metrics function independently. The Sebou and Bouregreg basins also experienced minor declines in their respective filling rates during this period.
