The Seton River is a 30 km long right tributary of the Fraser River in the Canadian province of British Columbia .

The Seton River forms the drain of Anderson Lake . It leaves it at its eastern end and flows 3 km in an easterly direction past Seton Portage Historic Provincial Park to the western end of the 22.5 km long Seton Lake . This section of the river was previously called Portage Creek . It was not until September 6, 1951 that the Seton River received its current name.

Seton Lake was raised 2 m by the Seton Dam . The water of the Bridge River , which runs further north, has been diverted to Seton Lake since 1961 as part of the Bridge River Power Project .

Below the Seton Dam, most of the water flows via the Seton Canal to a hydroelectric power station on the banks of the Fraser River. North of this, the lower reaches of the Seton River runs 4.4 km to its confluence with the Fraser River south of Lillooet . 3 km above the estuary, Cayoosh Creek , the most important tributary of the Seton River, meets the Seton River from the southwest. Originally, the Seton River was considered a tributary of Cayoosh Creek.

The catchment area of ​​the Seton River covers about 1880 km². The mean discharge near the mouth is around 28.6 m³ / s.
