A dramatic turnaround is underway in Catalonia as reservoirs experience a notable resurgence following recent heavy rainfall. The Sau Reservoir in barcelona is leading this comeback, mirroring a similar recovery in othre key water reserves like the Susqueda Reservoir. This advancement brings welcome relief in the ongoing efforts to combat drought conditions.

The reservoirs already react to the rains
The recent showers have significantly impacted reservoir levels. Internal basins have seen their water mass increase from 32.9% to 39.5% of their capacity as Friday. This increase is expected to continue, regardless of further rainfall.
As of this Monday, the reservoir system holds 275.65 cubic hectometers (HM3), which is equivalent to over 275 billion liters of water.
Drought
The Ter-Llobregat system, which supplies water to Barcelona and Girona, has seen its reservoirs rise to 40.8% capacity, a 7.9-point increase from Friday’s 32.9%.
These reservoirs now hold 249.7 cubic hectometers of water, a significant jump from last week’s 201.8. This time last year, they held only 90.27 cubic hectometers and were at 14.75% capacity.

Sau’s swamp triples its reservations
The Sau swamp has seen a dramatic increase, almost tripling its reserves from 7.6% to 21.5%. This marks a significant change after a continuous decline since last summer,which exposed the foundations of The Church and the old town.
Part of the reason Sau was so depleted is due to transfers to Susqueda. The ACA (Catalan Water Agency) conducts near-daily transfers to Susqueda because the larger reservoir ensures higher water quality. The Susqueda reservoir has increased by almost four points, rising from 38.1% to 41.7%.

It is not the only one: everyone grows
The recovery extends beyond Sau. The reservoir of Boadella Darkness has doubled its reserves, from 16.7% to 30.4%. The Baells is at 66.1% (compared to 53.9%),and the Llosa del Cavall is at 37.7% (compared to 34.3%).
Other reservoirs also show positive growth: Sant Ponç is at 58.01% (up from 56.4% on Friday), Foix is at 98.6% (up from 91.9%), Siurana is at 10.1% (up from 9.3%),and Riudecanyes is at 25.4% (up from 24.04%).
