The work for the new Poutès in the upper part of the Allier basin (France) is ongoing. And we will soon have an important momentum in the history of the Poutès dam. Indeed, at the end of the summer, the three sluices, each 14x5m and 20 tons, will be removed from the structure.
Since the end of May, the reservoir is completely emptied, revealing the old bed of the Allier river.
The bottom sluice gate is fully open. The machines will soon invest the area. A platform that will remain until 2021 (expected end of works) will be installed in front of the dam to allow work on the structure. A crane will then take the sluice, put them on the platform, where they will be cut before joining a revaluation workshop. The reservoir will be refill during the winter 2019. The removal of a part of the dam itself will then continue during spring of 2020 after the smolts downstream migration.
See schedule for work until 2021, and the history of Poutès dam in our dedicated webpage
Reminder, the Poutès dam will be lowered by 10 meters (now it is 17m) and completely retrofit to facilitate fish migration and sediment transport.
