Fish habitat and populations of the Elk River, Strathcona Park, Vancouver Island were investigated by the Fish Habitat Improvement Section in the summer and fall of 1978 as part of an overall program regarding possible rehabilitation of the Elk Valley. A decline in sport fisheries values in the Elk River and Upper Campbell Lake has occurred as a result of habitat alteration and destruction in the stream. Sports fish, including rainbow trout, cutthroat trout and Dolly Varden char were not abundant in the Elk River as adult resident or juvenile populations. Local abundance of juvenile salmonids was noted in some stable tributaries and mainstem side channels. Analysis of scales from a sample of Upper Campbell Lake fish indicated higher survival of fish which had spent one or more years rearing in a stream environment. A general enhancement strategy is outlined and recommendations for stream habitat improvement are made.
