Trapper Lake was identified as a potential sockeye salmon enhancement site in 1988 due to its under-utilized sockeye fry rearing potential. Several enhancement programs involving out-planted sockeye were attempted since, but were unsuccessful either due to out-plant and fish culture techniques or because of changes to the spawning and rearing habitat. It was observed that returning sockeye salmon from this enhancement program were nearly successful at negotiating a partial barrier near the outlet of Trapper Lake. This, coupled with the identified presence of non-anadromous sockeye (kokanee) suggested that Little Trapper Lake origin sockeye had negotiated the barrier in the past and may presently do so under certain water conditions. Improving the access for returning sockeye to Trapper Lake could result in a sustained increase in overall sockeye production from the Taku River.
