Monitoring Bull Trout Spawner Abundance in Williston Reservoir

Bull Trout: Steve Rooke

Williston Reservoir Bull Trout Spawner Abundance Monitoring

This project has three recommended options: 1) the core proposal consisting of redd counts in the established annual index reaches; 2) a recommended expansion of the redd count program to two‐to‐three new index sections in the Davis River, and two index sections in the Anzac River, to increase reliability of the surveys and increase First Nations training and employment; and 3) an application of the aerial redd count methodology (successfully applied to the Davis River in 2015) to the Ingenika River Watershed, to identify critical spawning habitats and estimate Bull Trout population size.
