Portage la Prairie is a small city in the Central Plains Region of Manitoba, Canada. As of 2011, the population was 12,996. The area of the city was 24.67 square kilometres (9.53 sq mi). Portage la Prairie is located approximately 75 kilometres (47 mi) west of Winnipeg, along the Trans Canada Highway, and sits on the Assiniboine River, which flooded the town persistently until a diversion channel north to Lake Manitoba (the Assiniboine River Floodway) was built to divert the flood waters.
The city is surrounded by the Rural Municipality of Portage la Prairie.According to Environment Canada, Portage la Prairie has the most sunny days during the warm months in Canada.The city became a major transportation centre due to its proximity to the river, and later, the location of the main lines of the country's national railways passing through the community (both the CPR and CNR Railways intersect in Portage; the only place in Canada where the two railways meet), all within a few hundred meters of each other. This has made Portage la Prairie one of the most ideal places for railway aficionados to view trains; approximately 72 trains pass through the city each day.
