The Dease River is a right tributary of the Liard River , which flows through the northwest of the province of British Columbia in Canada .
The river has its source in Dease Lake , but numerous rivers and streams that flow into this lake form the actual source of the river. The longest of these tributaries is Little Dease Creek , which rises near Snow Peak 50 kilometers west of the lake.
The river flows through the Cassiar Mountains and then forms the western boundary of the southern Yukon Plateau . After about 265 kilometers, in which the river runs mainly in a north-westerly direction, it flows into the Liard River at Lower Post .
Since the Dease River runs parallel to or near British Columbia Highway 37 ( Cassiar Highway ) for long stretches and access is relatively easy, it is very popular with water sports enthusiasts.
The river played a major role as a trade route and source of food for the Tahtlan and Kaska who settled on its banks . The first white visitor was John McLeod , a fur trader from the Hudson's Bay Company , who reached the river in the summer of 1831 and named it after the company's employee in charge of the Mackenzie River District - Peter Warren Dease .
