According to data from the Catalan Water Agency (ACA), water reserves in Catalonia's reservoirs stand at 623.86 hm³, reaching 92.01% of their total capacity. This volume represents an increase of seven percentage points compared to the state before the rainfall and nearly 180% more compared to the figures recorded one year ago.

The reservoirs that have experienced the most significant increases are Riudecanyes and Siurana, which have boosted their reserves by 50 and 25 percentage points respectively. Despite the generalized increase, only the Susqueda and Foix reservoirs have not registered an increase in reserves after the latest rains.

Regarding individual data, the Darnius Boadella reservoir is at 96.73% (61.23 hm³), closely followed by La Baells, which is almost full at 99.74% (91.74 hm³). Other important reserves include the Sau reservoir at 94.35% (156.45 hm³) and Susqueda at 92.1% (205.93 hm³).

Finally, the La Llosa del Cavall reservoir is at 89.96% (64.38 hm³) and Sant Ponç reaches 93.62% (22.85 hm³). Despite the large increases, Siurana (42.18% with 5.07 hm³) and Foix (86.54% with 2.92 hm³) remain key monitoring points.
