After the passage of the storm Jana, the reservoirs of Catalonia have experienced a moderate but positive recovery, and currently stand at 36% of their total capacity, according to the latest data updated to March 10, 2025 by the Catalan Water Agency.
In global terms, all the reservoirs of the internal basins of Catalonia have improved with respect to the 14.38% of a year ago, but are still far from the average values of the last five and ten years, located at 54.9% and 64.5%, respectively.
The comparison with the data of a year ago in the reservoirs of greater capacity, those of the Confederació Hidrogràfica de l’Ebre with capacity greater than 5 hm3 is positive. In 2024 they were at 44% of their average capacity, a figure that today is 15 points higher at 59%.
A trend that could alleviate Catalonia in the coming summer. Recall that in 2024, the scarcity of rainfall and high temperatures led Catalonia to decree a drought situation in several areas, imposing restrictions on water consumption for various uses. Reservoir reserves reached alarming lows, below 16%.
In a normal water situation, some 7,500,000 people consume 1 hm3 per day, as detailed by the Catalan Water Agency on its website. Hence the importance of critical levels of reservoirs such as Riudecanyes, with 1.31 hm3 at present, and the good data presented by others such as Susqueda (Osor) with 95 hm3.
In the most recent report, some reservoirs continue to present worrying values, as, for example, the Sau reservoir is only at 14.28% of its capacity, while Siurana is at a critical 9.69%. In contrast, other reservoirs such as Susqueda (40.9%) or Baells (61.04%) have shown a better recovery, although they are still below the historical average.
Recent rains have brought a respite for water supply, but experts warn that full recovery requires a prolonged period of sustained rainfall.
