I share good news in La Vanguardia Readers' Photos through these images of the Riera Major with a lot of water passing through Sant Sadurní d'Osormort thanks to the recent rains.
The Riera Major originates in Montseny, municipality of Viladrau, passes through Sant Sadurní d'Osormort and ends its course in the Ter River, downstream of the Sau reservoir.
One of the curiosities of the Riera Major as it passes through Sant Sadurní d'Osormort is that you can see a staircase of pieces.
It is a type of transfer system, a channel with artificially increased roughness, which communicates the level of the reservoir upstream of the dam with the level of the river downstream of it.
The shape of the ladder must allow fish migrating in the river to cross the dam. It has an eminently ecological function.
