France : “Nouveau Poutès dam” : observation of the lenght of the reservoir

> Watch the ERN Video “Overflight of the Allier River upstream of the Poutès dam” 

Only since the second week of March it has been possible to turbine. Indeed, since the closing of the gates, the Allier had never exceeded the reserved flow (5m3/sec). According to EDF, the operating tests were positive.

On March 15, with a total flow of 15m3/sec, we were able to observe the creation of a reservoir over a few hundred meters. Further upstream, the Allier, deeper than in the ‘transparency’ mode of the dam over a few hundred meters, remained in its former minor bed with a good current favorable to migration.

On Thursday March 24th, this time with a total flow of the Allier of 10M3/sec, SOS Loire Vivante – ERN  flew over the site at high altitude with a drone to better observe the evolution of the bed and the water retention area. In addition, with the authorization of EDF, we flew at low altitude as close as possible to the dam and the water intake. The observations of March 15 were confirmed.
