During the 2006 review of the Alouette Water Use Plan (A-WUP), the consultative Alouette Monitoring Committee identified the restoration of an anadromous sockeye salmon run as a key issue in the Alouette River system.

Construction of the dam in the 1920s impounded the reservoir and extirpated the Sockeye run soon after. As a means of re-establishing the stock, a spring surface release from the dam was integrated into the A-WUP. The testing of a specific surface release of 3m3s-1 from April to June has facilitated Sockeye out-migration from the reservoir. Since 2005, smolts have successfully out-migrated through the spillway gate during the spring release and to the ocean via the Alouette River (Table 1, Mathews et al. 2023).
