Red Deer River (Manitoba)
Red Deer River is a river in the Canadian provinces of Saskatchewan and Manitoba. It has its source at Nut Lake in east central Saskatchewan and from there, it flows east towards Manitoba where it empties into Dawson Bay of Lake Winnipegosis. To the north of Red Deer's basin is the Saskatchewan River, to the south-west is the upper Assiniboine River, and to the south-east is Swan River. Course 
The Red Deer River begins at the north end of Nut Lake near Highway 349 and west of Porcupine Hills in east central Saskatchewan. From Nut Lake, it heads north past Greenwater Lake Provincial Park towards Pré-Ste-Marié. From there, near the junctions of Highways 679 and 773, it turns east towards the town of Hudson Bay and the Hudson Bay Regional Park, which is the site of a former North West Company fort named Fort Red Deer River. From Hudson Bay, it continues eastward and is the divide between the Pasquia Hills to the north and the Porcupine Hills to the south. It also passes through provincial forests such as Porcupine and Pasquia. From the forests and hills, it continues eastward into Manitoba where  past the border, it opens up into Red Deer Lake. The river continues from the east side of Red Deer Lake for about  until it empties into Dawson Bay of Lake Winnipegosis. Near the point where it empties into Dawson Bay, it crosses Highway 10, which is part of the Northern Woods and Water Route. That is also the location of Red Deer River Provincial Park. In 1757, a Hudson's Bay Company fur trading post was established alongside the Red Deer River near the village of Erwood. In 1790, the North West Trading Company set up a trading post at the mouth of the Etomami River called Fort Red Deer River. On the river bank opposite the mouth of the Etomami River, there are the remains of another fort that is believed to be that of the American Fur Company. Tributaries
