One national series, in gigawatt-hours. RTE publishes a weekly hydraulic stock for France and states the maximum associated with that series (3,591 GWh). The percent is stock divided by that maximum. It is not a share of every French reservoir. RTE does not name the reservoirs in this series, and this page does not add a reservoir that publishes only a water level in metres.
