"Écourues" ? What in a duck's name is that ?

“Écourues” is our local lingo for river closing. Rest assured : it doesn’t mean we will stop working ; on the contrary !

The écourues are an important part of the life of our rivers. All the dams are opened in order to set the river back to its natural bed (a lot shallower than what we are used to see !).

In the Rivers of Western France®, the river closing alternate between the Mayenne and Oudon, the Sarthe, and the Loir.

And, this year, you guessed it : it is the turn for the Oudon and the Mayenne river closing.

Mayenne river closing in 2024 : what for ?

The departments (counties) of Maine et Loire and Mayenne are undertaking these “écourues” for several reasons. Among others :

For example : find all the leaks and used seals in locks, hydroelectric dams, etc …

When will the closing of the Mayenne river happen in 2024 ?

The “écourues” will start in September the 2nd and will be done in several phases, by area :

  • From September the 2nd : from Mayenne to Bootz Lock (Laval
