The Marguerite River marsh, located in Bécancour, was developed by Ducks Unlimited Canada (CIC) in 1999. The work consisted of damming and flooding former abandoned agricultural land to create a permanent 8-hectare swamp. The borrowing bank for the construction of the dike (outer channel of the marsh) was excavated to provide good spawning and nursery habitat for fish. In 2014, a committee to beautify the Laviolette Bridge was set up and the Marguerite River marsh area was targeted for development projects. In addition, restoration work is planned for the loan bank's control structure in 2016-2017.
The Comité Zip Les Deux Rives has produced a document that aims to establish environmental conservation objectives, the enhancement elements that can be achieved, and the prohibitions affecting the site.
