Not to be confused with [River Seaton](/source/River_Seaton).

The **Seton River** is a [tributary](/source/Tributary) of the [Fraser River](/source/Fraser_River) in the [Canadian province](/source/Provinces_and_territories_of_Canada) of [British Columbia](/source/British_Columbia). The name is relatively new, and encompasses what had formerly been the Seton Portage River or Portage Creek (aka Portage River) and Seton Creek[4] (which shows up on some topos as "Section Creek" due to a mis-read of old hand-written maps).[citation needed]

## Course

The Seton River originates at the foot of [Anderson Lake](/source/Anderson_Lake_(British_Columbia)) and runs initially for only 3 km to the head of [Seton Lake](/source/Seton_Lake). From the foot of Seton Lake to the Fraser its remaining course is 5 km in length, with much of its flow diverted via the [Seton Canal](/source/Seton_Canal) to the [Seton Powerhouse](/source/Seton_Powerhouse) (also known because of its location as the Lillooet Powerhouse). The river's course is generally eastward to join the Fraser River at the town of [Lillooet](/source/Lillooet,_British_Columbia).[4] The upper section between the lakes was historically known as the **Portage River** or **Seton Portage River**; its flow is augmented by [Whitecap Creek](/source/Whitecap_Creek), from the northwest midway along its length, and by Spider Creek nearer Seton Lake. The lower section was formerly named **Seton Creek** and commonly mislabelled on some maps as **"Section Creek"**, apparently a misrendering of the archaic spelling **Seaton Creek**. Just below the foot of Seton Lake its flow is considerably augmented by the addition of the waters of [Cayoosh Creek](/source/Cayoosh_Creek), a name which originally applied all the way to the Fraser until the name "Seton River" was coined by the Canadian Geographic Names Board in 1950.[5] "Cayoosh Creek" is still generally applied to the river below that point by local residents, often with the spelling "Cayoose Creek", which is also the old name of the [Sekw’el’wás First Nation](/source/Sekw%E2%80%99el%E2%80%99w%C3%A1s_First_Nation) (i.e. "Cayoose Creek Indian Band").

Above Anderson Lake, the main watercourse of the Seton drainage is named the [Gates River](/source/Gates_River); numerous creeks along Anderson lake contribute substantially to the volume supplied by the Gates; these include [McGillivray Creek](/source/McGillivray_Creek), [Haylmore Creek](/source/Haylmore_Creek), and [Lost Valley Creek](/source/Lost_Valley_Creek).
