The Etchemin River, which had become been the victim of pollution for decades, became the topic of conversation in 1993, when a few residents of Saint-Léon-de-Standon began to work on a project to revive the Atlantic salmon in the river. The project was scoffed at in the beginning; damming, logging along the Etchemin's shore, agricultural runoff and dumping had polluted the river so much that the last Atlantic salmon had been last seen there some two centuries ago. Although the odds were against them, the locals from different riverbank communities began work on the river. They formed the Comité de restauration de la rivière Etchemin (CRRE). Work then began on planting over 15,000 trees on the riverbanks, making salmon-friendly rapids and shelters for spawning. In 2002, the first adult Atlantic salmon was spotted in the river.
