Apparently, they're in the process of repairing/restoring the locks. The water level was lowered for this purpose. This was the case in June 2024 - @Lydie attached a picture showing that the water level is back to normal. This means that the work on the locks that were repaired is now complete.

Like the many locks on the Nantes-Brest canal, the Saint-Algon lock has long allowed boats to transport goods from one city to another. Today, the lock house is only the breath of a memory of this river period.
