It has rained these last days of Holy Week. Not one day, but several. The Ter river flows down in Osona with more force and with more water flow. In parallel, the Sau reservoir has once again exceeded 5%, with 8.59 hm³. But why does it seem like it's not getting better?
This is what the photographs shared in La Vanguardia's Readers' Photos tell us. On the one hand, they show us the Ter river looking good, but, on the other, we see how images of drought in the reservoir still predominate.
Sau is a swamp that, in times of drought, retains less water, because it is encouraged to drain into the neighboring Susqueda reservoir (both drink from the Ter).
In fact, when the reservoir was below 5% (it has even reached 1%), it also drained into the other reservoir to preserve the quality of the water.
This could explain why images of extreme drought still persist in a swamp that has been receiving more water from the Ter River these days compared to previous weeks and months.
The Sau reservoir, located in the municipality of Vilanova de Sau, is at the foot of the Guilleries massif. The abysses that surround the swamp are spectacular and are reflected in its waters. Sau is part of a system of three reservoirs, along with those of Susqueda and Pasteral, which unites the regions of Osona and La Selva. Of the three, the last is the one that is best withstanding the consequences of the drought.
