Raush River

The Raush River is a tributary of the Fraser River in British Columbia, Canada. It drains a watershed of approximately 100,000 hectares (250,000 acres) on the eastern flanks of the Cariboo Mountains, a sub-range of the Columbia Mountains.[1] The river joins the Fraser near the community of Dunster in the Robson Valley. The river's name is the result of a transcription error; it was originally called the Rivière au Shuswap, this was recorded on some maps as R.auSh., which then became Raush on official maps.[2] Its source is the Raush Glacier, and major tributary creeks include Black Martin and Quanstrom.

Two areas of the river are protected: the Lower Raush Protected Area protects 1,279 hectares (3,160 acres) near the river's mouth, while the Upper Raush Protected Area covers 5,582 hectares (13,790 acres) of its upper reaches.[3] More than 50 kilometers of the river are navigable, and are used by kayakers, canoeists, and jetboaters.[4]
