Morocco’s major dams have recorded a sharp recovery in water reserves, signaling a significant improvement after years of severe drought and raising optimism for the agricultural season and drinking water supplies.

According to the latest daily bulletin from the Ministry of Equipment and Water, the country’s overall dam fill rate reached 75.88%, compared with just 40.25% during the same period last year.

Official figures showed that the total volume of stored water reached 13.059 billion cubic meters, out of a total natural storage capacity of 17.21 billion cubic meters.

The near doubling of reserves within a year reflects the impact of heavy rainfall and snowfall recorded across several regions of the country, helping replenish reservoirs that had been under severe pressure in recent years.

A closer look at Morocco’s river basins shows strong improvements across most regions, with several basins approaching full capacity.

The Tensift basin recorded the highest fill rate at 96.02%, up from 54% a year earlier. The Loukkos basin maintained high levels at 92.76%, while the Bouregreg basin rose sharply from 43.25% last year to 92.16%, securing drinking water supplies for the Rabat-Casablanca corridor.

The Sebou basin, Morocco’s largest water reservoir system, reached a fill rate of 87.67%, holding more than 4.7 billion cubic meters of water, compared with 55.33% last year. Al Wahda Dam, the country’s largest dam, also posted a strong fill rate of 87.64%.

In the Oum Er-Rbia basin, considered a critical source for agriculture in central Morocco and one of the hardest hit by recent droughts, the fill rate climbed to 63.95%, marking a major recovery from previously alarming levels.

Southern regions also showed improvement. The Souss-Massa basin increased from 22.28% last year to 56.29%, a development expected to support the region’s intensive agricultural activity.

Meanwhile, the Draa-Oued Noun basin remained at more modest but improving levels, rising to 39.22% from 34.59% a year earlier, while the Ziz-Ghris basin remained relatively stable at 54.06%.

The improved dam reserves are expected to ease pressure on irrigation systems and urban water supply networks, offering relief after several consecutive dry years that had raised concerns over long-term water security in Morocco.
