About this reservoir

Sistema Valle de Arán is a reservoir in the Ebro basin, Spain.

Its readings come from Spain's Ministry for the Ecological Transition (MITECO), from its weekly Boletín Hidrológico.

The value is the water stored in the reservoir, in cubic hectometres (hm³; one hm³ is a million cubic metres), as MITECO's weekly bulletin gives it for each Tuesday.

MITECO calls every value of its bulletin provisional and subject to review and validation.
