Catalan reservoirs in internal basins stand at 78.35% today

The internal basins of Catalonia are currently storing 78.35% of their capacity, with **531.29 hm³** of water held back. The reservoirs of the Ter-Llobregat system, such as Sau and Susqueda, are the most significant for supply.

The level of Catalan reservoirs is once again the thermometer for water availability in the region, as reported by El Periódico in its daily monitoring of reserves. Rainfall, consumption, river contributions, and water management explain why the stored percentage can change from one day to the next.

After the drought of 2023 and 2024, the rainfall in 2025 and 2026 has been recovering reserves. The evolution of the reservoirs remains crucial for assessing the water situation and supply needs.

Data from November 5 places the total of the internal basins at 78.35% capacity, with 531.29 hm³ stored out of a total of 678.07 hm³. This figure corresponds to the information published by the Catalan Water Agency, which also allows for checking the available volume and the evolution of each reservoir.

The Ter-Llobregat system is one of the main supply networks in Catalonia, providing water to a significant part of the population, especially in the Barcelona and Girona areas. It has five main reservoirs: Sau, in Vilanova de Sau (Osona); Susqueda, in Osor (la Selva); la Baells, in Cercs (Berguedà); la Llosa del Cavall, in Navès (Solsonès), and Sant Ponç, in Clariana de Cardener (Solsonès).

For the local resident, the combined reading of these reservoirs indicates how much water remains for domestic supply and agricultural and industrial uses in their area. Those wishing to track the exact figure for each reservoir can consult it on the Catalan Water Agency's website, where the percentage and stored volume are updated.
