Which reservoirs these are
They are the ones the ACA publishes every day as open data: the reservoirs of Catalonia's internal basins above 2 hm³, plus Siurana, which lies in the Ebro basin but is run by the ACA together with Riudecanyes. El Pasteral, the small dam on the Ter below Susqueda (2 hm³ according to the ACA), is not included.
For the Catalonia total and the Ter-Llobregat system that supplies the Barcelona area, see Catalonia reservoir levels today.
What about Rialb, Oliana, Canelles or Riba-roja?
The reservoirs of the Catalan part of the Ebro basin (Rialb, Oliana, Canelles, Santa Anna, Talarn, Camarasa, Mequinenza, Riba-roja…) are in the basin of the Ebro Basin Authority (CHE), which publishes their data. The CHE warns that the real-time data of its SAIH system are not official until it validates them, so we do not give them pages. The ACA includes a summary, with data supplied by the CHE, in its daily bulletin.
