What's this "écourues 2025" business all about ?

This is indeed a term you will hear in the mouth of people living near the river here. THe écourues, which means a river closure, is a time where the waterway returns to its naturel bed. In other words : the dams are opened, followed by a drastic lowering of the water level …

But ... what for ?

But, what is the aim of this, are you asking yourself …

Indeed, there are several reasons for this operation.

First of all, it is the perfect moment to do a thorough cleaning of the whole river. 

Secondly, it is an opportunity to check the condition of structures such as bridges, dams, locks, etc …

And most importantly, it is a critical time for the administrators of the Rivers of Wester France® (the departments of Sarthe, Maine et Loire and Mayenne).It is the time when important maintenance can be done on areas that would normally be underwater.

And, in 2025, the écourues are concerning the Sarthe, Maine and the souther part of the Mayenne rivers.
