Book excerpt: Compte tenu de la fragilité de notre environnement et des limites de notre planète, une activité économique durable doit assurer un usage polyvalent des ressources; elle doit aussi tenir compte de la qualité de vie du genre humain et favoriser le maintien de la diversité biologique. [...] Une partie seulement des eaux de cette rivière rejoint celles du fleuve à la hauteur du lac Saint-Louis par les canaux de Vaudreuil et de Sainte-Anne, pour ensuite passer dans les rapides de Lachine et le grand bassin de La Prairie. [...] Les conditions naturelles de cette partie du secteur d'étude ont été bouleversées lors de la construction de la Voie maritime du Saint-Laurent et de la création de ce qu'on appelle désormais le petit bassin (voir la section 4.1). [...] À l'heure actuelle, les rapides de Lachine et le grand bassin de La Prairie correspondent à l'essentiel du débit fluvial; le canal de Lachine et le canal de la rive sud ne détournent qu'une infime partie de l'écoulement (moins de 2 p. 100). [...] Au cours de la période de migration printanière, de la mi-mars à la mi-juin, ce sont surtout des rassemblements de canards plongeurs que l'on peut observer en aval de l'île aux Hérons, au sud de l'île des Soeurs et au centre du grand bassin.

Available in PDF, EPUB and Kindle. Book excerpt: The first major impact seems to have been caused by forestry operations and the burgeoning industrialization in the 19th century: log driving from the Ottawa River to Quebec City, the appearance of dams and sawmills along tributaries, and the building and commissioning of the first hydroelectric power stations. [...] As the list of toxic substances found in the aquatic environment grew longer, the general public came to put the quality of the environment at the top of its list of concerns. [...] One of the objectives of the Action Plan, that has been maintained in SLV 2000, was the preparation of a comprehensive assessment of the environment in the Quebec stretch of the river. [...] As the millennia passed, the river carved a bed in the unconsolidated sediments and clays that had been left on the floor of the ancient arm of the sea. [...] In the Greater La Prairie Basin, we have detected the existence of a mixing zone along the north shore, while the centre and the south shore are characterized by water typical of the Great Lakes plus the contribution of local tributaries.
