The Powell River is a river in the northern Sunshine Coast region of British Columbia, Canada that flows a short distance through the eponymous city of Powell River, British Columbia to enter the Salish Sea.
 It is one of the shortest rivers in the world, along with the Nautley River (also known as Nautley Creek).
Powell River is a city on the northern Sunshine Coast of southwestern British Columbia, Canada.
 Most of its population lives near the eastern shores of Salish Sea, which is part of the larger Georgia Strait between Vancouver Island and the Mainland.
 With two intervening long, steep sided fjords inhibiting the construction of a contiguous road connection with Vancouver to the south, geographical surroundings explain Powell River's remoteness as a community, despite a relative proximity to Vancouver and other populous areas of the BC Coast.
 The city is the location of the head office of the Powell River Regional District.
The Powell River in the United States rises in southwest Virginia and flows into East Tennessee.

Powell Lake is a lake in the northern Sunshine Coast region of British Columbia, Canada, adjacent to the city of Powell River, which sits on the low rise of land forming a natural dam between the lake and the Strait of Georgia.

 It serves as a reservoir for a small hydroelectric generating station which was built to serve the city's paper mill, and also served as a water supply for that paper mill.
Southwest Virginia, often abbreviated as SWVA, is a mountainous region of Virginia in the westernmost part of the commonwealth.
 Southwest Virginia has been defined alternatively as all Virginia counties on the Appalachian Plateau, all Virginia counties west of the Eastern Continental Divide, or at its greatest expanse, as far east as Blacksburg and Roanoke.
 Another geographic categorization of the region places it as those counties within the Tennessee River watershed.
 Regardless of how borders are drawn, Southwest Virginia differs from the rest of the commonwealth in that its culture is more closely associated with Appalachia than the other regions of Virginia.
 Historically, the region has been and remains rural, but in the 20th century, coal mining became an important part of its economy.
 With the decline in the number of coal jobs and the decline of tobacco as a cash crop, Southwest Virginia is increasingly turning to tourism as a source of economic development.
 Collectively, Southwest Virginia's craft, music, agritourism and outdoor recreation are referred to as the region's "creative economy."

 The airline was founded by Daryl Smith,Lynn Mulhall and George Percy in 1975 after acquiring Air West's Powell River operations.

 In 1981, the airline was awarded the right to operate the Vancouver-Powell River route, and for this purchased a Convair 440.
 In 1987, Powell Air and Air BC's Port Hardy operations merged to form Pacific Coastal Airlines.
Cranberry, formerly Cranberry Lake, is a community and neighbourhood within Powell River, British Columbia, Canada.
 It was incorporated as the Village of Cranberry Lake in 1942 and was merged into Powell River in 1955 as that District Municipality was expanded.
 The settlement's original name derives from the lake of the same name, around which grew cranberries on the peat-rimmed shoreline.
 Because there was another Cranberry Post Office in British Columbia, the word "lake" was retained in the name of both post office and the village municipality although it has since been dropped since amalgamation into what is now the City of Powell River.
