Atla Lake tributaries were surveyed by the Fish Habitat Improvement Section in mid-July 1980. The primary objective was to identify options for fisheries enhancement in view of (i) increasing development and (ii) possible alienation of spawning and rearing habitats in the outlet tributaries through construction of a lake-level control structure. Once the options had been identified, projects were to be priorized according to their ability to increase public awareness of fisheries concerns. Present rearing capability in inlet tributaries was judged to be insufficient to support the existing lake fishery without additional recruitment from outlet sources. Instream spawning and rearing stages do not appear to limit the Alta Lake creel at the present time. Over-recruitment to the lake probably contributes to relatively slow lake growth. Therefore, to maintain present size of creeled fish, projects which could substantially increase juvenile recruitment to the lake should not be considered at this time. Production
