Shuswap River

The basin of the Shuswap River (pronounced /ˈʃuːʃwɑːp/) lies northeast of the Okanagan Valley in British Columbia, originating in the central Monashee Mountains. It is the upper part of the drainage better known to British Columbians as belonging to Shuswap Lake and the South Thompson River. The river's drainage basin is over 1,969 square kilometres (760 sq mi) in area.

The river is in three sections, an upper part beginning at Joss Pass, at the northern end of the Sawtooth Range of the Monashees and emptying into Sugar Lake southeast of the south end of that range. The next section of the river curves south from Sugar Lake to wind up running north again before entering Mabel Lake, which is a fair-sized mountain lake as typical of much of Interior British Columbia (e.g. Shuswap and Adams Lakes elsewhere in the same season, the original Arrow Lakes and Kootenay Lake). Below Mabel Lake is the last stretch of the river west towards the town of Enderby at the north end of the Okanagan Corridor, after which the Shuswap River drains into Mara Lake. Mara Lake is connected via a channel named Sicamous Narrows to the Salmon Arm of Shuswap Lake at Sicamous which empties via the 3.5 km canal-like Little Shuswap River into Little Shuswap Lake. At that lake's lower end is Chase and the beginning of the South Thompson River.

Tributaries of the Shuswap River include Wap Creek, by which a short pass at Three Valley Gap connects to Highway 1 between Craigellachie and Revelstoke.
