The overall fill rate of Tunisia’s dams stood at 35.5% as of March 21, according to the latest data published on Friday by the National Observatory of Agriculture (ONAGRI).
Water reserves in these dams have slightly decreased by 3.6%, reaching 839.871 million cubic meters (m³), compared to 871.488 million m³ during the same period last year.
However, the decline in these reserves is even more significant (at 8%) when compared to the average recorded over the past three years.
It is important to note that the dams in the north show a fill rate of 40.8%, with water reserves amounting to 756.376 million m³, representing 90% of the total reserves available in all the country’s dams. The Sidi Barrak dam alone accounts for 25% of Tunisia’s total water reserves, with a fill rate of around 73%.
As for the dams in the center and Cap-Bon regions, their fill rates are limited to 13.8% and 34.6%, respectively.
According to ONAGRI, water inflows during the entire season (from September 1, 2024, to March 20, 2025) amounted to 665.088 million m³, a 52% drop compared to the average for the period.
On March 21, water inflows recorded in the dams reached 1.120 million m³, with almost all of it coming from dams located in the north.
The total water usage from the dams on the same day was 1.358 million m³.
