he Kokanee Age Structure Population Analysis (ALUMON #6) is in its third year of a multi-year study that was undertaken as part of a larger monitoring protocol developed under the Alouette Reservoir Water Use Plan (WUP). The focus of this component is to address concerns about the kokanee population and whether the current kokanee population is demonstrating recruitment limitation and whether any identified recruitment limitation is related to operations-based limitations to reproductive success. This study begins to address three important management questions in the Alouette WUP which are: 1) Is the existing kokanee population in the Alouette Lake reservoir (ALR) recruitment limited? 2) If there is evidence of a recruitment constraint to productivity, can it be linked to reservoir operations? 3) If found linked to reservoir operation, what is the nature of the relationship and can it guide the development of possible mitigative reservoir operations?
