Steelhead studies were conducted in the upper Sustut River. The objectives of the studies were to determine the time of arrival, abundance, and migration behaviour of steelhead and to assess the upper Sustut River's suitability as an index stream for upper Skeena steelhead stocks. As well, potential steelhead enhancement opportunities and the extent of Indigenous fisheries in the upper river were evaluated. Methods used included a combination of snorkel observations, radio telemetry, and a fish counting fence.
