caption_attribution_description: Français&#160;: Rivière l'Acadie, vu de l'aval à partir du pont menant à l'Île Goyer, soit à 1,1 km de sa confluence avec la rivière Richelieu.
context_page_description: The Acadia River flows Northerly over 82 km through seven municipalities in the MRC La Vallée-du-Richelieu, Les Jardins-de-Napierville and Le Haut-Richelieu, in Montérégie, on the South Shore of St. Lawrence river, the Quebec, Canada. The Acadia river empties into the Richelieu River, in Carignan, skirting the city of Chambly by the north.
context_section_description: The Acadia river takes it source from some streams at the foot of mountains near the Canada-United States border in the Hemmingford Township at Hemmingford. It flows north, almost in parallel to the Richelieu River (on west side). Besides passing through some villages (Napierville, Acadia and Chambly), Acadia River flows through agricultural and forest environments. The river is bordered by campaigns decorated with historical and modern buildings. Formerly, from Saint-Cyprien-de-Napierville and towards its mouth, heritage routes ran along on each side of the river route, but some segments of roads are now extinct. In winter, ice roads on the river allowed transportation vehicles drawn by animals or on foot, by avoiding cast parallel roads sometimes poorly managed and unplowed.
  The course of the river flows through seven municipalities (or cities): Hemmingford, Saint-Patrice-de-Sherrington (where it flows eastward) Saint-Cyprien-de-Napierville, Napierville, Saint-Jean-sur-Richelieu (Saint-Luc and Acadia sector), Carignan and Chambly.
  Description of the route of the river
  The course of the river is meandering between the village of Acadia and Chambly Road (Quebec Route 112) at the limit of Chambly and Carignan. This segment of the river is ideal for spring flooding or heavy floods of the river, because of the low gradient.
  In Saint-Jean-sur-Richelieu (Saint-Luc area), the natural environment along the river l'Acadie with an area of 645,834 sq.ft (6 ha) is an ecological heritage. In a conservation goal, the sector is subject to specific rules forbidding including any tree cutting, all new construction and all remblaiement.
  Acadie River through the historic village of Acadie. Acadians, subject to a large deportation, generally from Boston, had settled in this area in 1782. They built the parish church, near Acadie River.
  Mouth of the river
  After touring the montérégienne plain, Acadia river empties into the Richelieu River at the mouth of the Chambly Basin; the mouth of the river is part of Carignan. In the last segment of its course, the river flows along the road 223 (Bellerive path) that bypasses by the North the Demers Island and Grande île (Great Island), located at the north of the Chambly Basin.
