Continental Divide of the Americas
In Canada, the primary continental divide is named the Continental Divide of the Americas, or Nice Divide. It roughly follows the ridge of the Rocky Mountains. The water separated alongside the Nice Divide ultimately reaches one of many Arctic, Atlantic or Pacific Oceans (except for sure “closed watersheds” in Saskatchewan and Alberta). Vital sections of the Alberta-British Columbia and Yukon-Northwest Territories borders observe this pure boundary, as does the Nice Divide Path.
The Canadian portion is just a fraction of the Continental Divide of the Americas. In its entirety, the Nice Divide spans nearly the entire size of North and South America, from Cape Prince of Wales in Alaska to the southern tip of South America, operating atop the Rocky Mountains, the Sierra Madre Occidental vary and the Andes.
Whereas different continental divides exist in North America, scientists don’t agree on the exact quantity. Vital examples in Canada are the Arctic Divide, the Laurentian Divide and the St. Lawrence Divide.
The Arctic Divide (typically known as the Northern Divide) runs from Snow Dome mountain, on the sting of the Columbia Icefield in Jasper Nationwide Park, throughout Alberta, Saskatchewan and the Northwest Territories to lastly attain Nunavut. Three drainage basins meet at Snow Dome, a phenomenon known as a hydrological apex. This happens as a result of Snow Dome is on the junction of two continental divides: the Nice Divide and the Arctic Divide. Precipitation that falls on Snow Dome mountain can find yourself within the Pacific (if it falls on the west facet of the Nice Divide), the Atlantic (if it falls on the east facet of the Nice Divide and the south of the Arctic Divide), or the Arctic Ocean (if it falls on the east facet of the Nice Divide and the north of the Arctic Divide).
The Laurentian Divide spans a lot of the width of the continent, operating from Montana to Labrador. Its path begins in america’ Rocky Mountains, persevering with by southern Alberta and Saskatchewan earlier than swinging again into america and reaching the southern tip of the Crimson River. Rivers south of this line are a part of the Missouri-Mississippi River system. The divide then comes again up into Canada simply northwest of the Nice Lakes. At that time, any water draining south of the Laurentian Divide leads to the Nice Lakes-St. Lawrence River basin. Water draining to the north of that line flows towards Hudson Bay. The divide then cuts by Ontario and Québec and runs alongside the much-eroded Canadian Protect to achieve the border between Québec and Labrador. Water flowing from this part of the divide was diverted into dammed reservoirs to generate hydroelectric energy as a part of the James Bay Venture.
St. Lawrence Divide
The St. Lawrence Divide runs south of the Nice Lakes in america earlier than following the St. Lawrence River. Water travelling north of this line leads to the Nice Lakes-St. Lawrence basin. Water south of the road leads to the Mississippi (after which the Gulf of Mexico) or the Atlantic basin.
