Salmon River, Salmon fishing river in Strathcona Regional District, Canada.

The Salmon River rises at 1,240 m in the highlands northwest of Strathcona Provincial Park and runs 92 km, flanked to the west by the 1,741 m Mount Judson, before turning northwest and reaching Johnstone Strait at Sayward. Its lower course carries numerous meanders, and its main tributaries, the Memekay and White rivers, join from the left.

The Salmon River's modern history centres on a weir built in the 1950s at river kilometre 58, above which a 7 km diversion channel carries water east to Brewster Lake and on to Campbell Lake, feeding hydropower plants on the lower Campbell River. When built, the weir was no barrier to migrating fish because a natural obstacle lay downstream; the BC Ministry of Environment removed that obstacle in the 1970s, opening the river up to the weir. BC Hydro operates the weir, and recent plans call for a fish ladder to open the headwaters to migratory fish.

The river's English name means "salmon river", and its lower course near Sayward is marked by numerous meanders. The Sayward Valley stretch carries the river past the village before it enters Johnstone Strait at Kelsey Bay.

The river rises at 1,240 m in the highlands northwest of Strathcona Provincial Park and runs 92 km to Johnstone Strait at Sayward, with the lower course full of meanders. Its main tributaries, the Memekay and White rivers, both join from the left. A weir built in the 1950s at river kilometre 58 diverts water 7 km east to Brewster Lake; BC Hydro operates it.

A weir built at river kilometre 58 in the 1950s diverts water 7 km east through a canal to Brewster Lake, then south to Campbell Lake, feeding hydropower plants on the lower Campbell River. Its operator is BC Hydro; a natural barrier downstream once blocked fish, and when the BC Ministry of Environment removed it in the 1970s, migratory fish could reach the weir.
