WLR Monitoring Study CLBMON-06 (Year 3) Kinbasket Reservoir Juvenile Bull Trout Life History and Habitat Use Assessment
Author: M. Kang, W.G. Warnock
This four-year study was designed to answer management questions related to i) basic life history and habitat use characteristics of juvenile Bull Trout in Kinbasket Reservoir; ii) potential effects of reservoir operation on juvenile Bull Trout; iii) identification of modifications to the operation of Kinbasket Reservoir to protect or enhance juvenile Bull Trout populations.
A total of 15 juvenile Bull Trout were captured in fyke nets set at 11 locations throughout Kinbasket Reservoir. Habitat assessments indicated that nearshore areas of Kinbasket Reservoir likely provide sub-optimal temperature and substrate conditions for juvenile Bull Trout. Cover was lacking in most areas as fine/sand substrate made up 71% of sites, while gravel and cobble substrates made up only 29% of sites
A total of 12 juvenile Bull Trout were detected by the fixed antenna reader installed near the confluence of Packsaddle Creek with Kinbasket Reservoir (Dec. 4, 2016 to June 22, 2017). Mean length at tagging of detected Bull Trout was 115.5 ± 1 mm and mean weight at tagging of detected Bull Trout was 15.1 ± 9.88 g. Inclusion of Bull Trout detection data from additional individuals in Packsaddle Creek over an extended study period in 2018 will provide useful information on the assessment of outmigration.
