Originally, through BC Hydros Water Use Plan for the Alouette Watershed, a spring surface release from the Alouette Dam has allowed for kokanee/sockeye smolts to migrate to the ocean from 2007 to 2016. The first surface releases occurred in 2005 and in 2007 the first adult sockeye returned to the Alouette Watershed. The 2016 Alouette sockeye salmon run saw 6 adults returning between July 19 and August 7, 2016. All six sockeye were in great condition and were sampled at the Allco trap location before being transported to Alouette Lake. Fork length measurements for all six sockeye were taken along with scale and tissue samples. The measurements indicated an average fork length of 60cm.
Of the 6 scale samples taken by BC Corrections, four were useable for aging with all four of these adults being four years old. One of the remaining two was upside down and could not be read and the other was a partial reading, recording two years spent in the ocean. The genetic sampling identified all adults originated from Alouette stock. Between the return years of 2005-2012, the smolt to adult (return to the hatchery fish fence) survival of the Alouette sockeye has ranged from a low of 0.06% in the 2011 smolt year to a high of 1.33% in the 2008 smolt year. (Mathews et al. 2015).
The peak of the 2016 Alouette adult sockeye return was on 26 July, when 2 fish arrived at the Allco fish fence. Since 2007, up to and including the 2016 season, 318 adult sockeye salmon have returned to the Allco fish fence.
This project aligns with the Fish and Wildlife Compensation Programs Alouette Watershed Coastal Action Plan and the Alouette Salmonid Action Plan. The priorities which are addressed are
Sub-objective 1 Maximize the viability of anadromous salmonids. Compensation requires increasing present biological productivity to offset hydro development-related declines in productivity. There are myriad ways to compensate for fisheries impacts, and some work better for some species than others and some may be more suited to certain physical settings.
