Component 2.2 : Predicting the Entrainment Risk of Fish in Hydropower Reservoirs
Objectives :
The objectives of the component Predicting the entrainment risk of fish in hydropower reservoirs are:
- to generalize the knowledge of intake-induced flow hydraulics for different sites, under various temperature stratification regimes and reservoir levels, and different hydropower operations.
- to determine the biotic characteristics that influence the entrainment risk of several key fish species
- evaluate the spatial ecology of adult bull trout from different spawning tributaries to identify the extent to which they encounter the Mica forebay region.
- document the thermal habitat use and vertical distribution of burbot in the reservoir including in the vicinity of the forebay.
- provide a detailed understanding of bull trout, kokanne, and burbot behaviour in the immediate vicinity of the Mica forebay relative to dam operations to quantify and describe patterns of entrainment.
- quantify survival and behaviour of tagged bull trout, burbot, and kokanee that are entrained and pass through the turbines to the river below.
- develop a seasonal model of entrainment risk for adult bull trout, burbot, and kokanee that could serve as a model for future entrainment risk assessments in Canada and beyond;
- determine how physical mitigation alternatives (such as barrier nets, thermal curtains, etc.) affect upstream flow fields and how various mitigation options perform under various hydraulic and operation conditions.
Sub - Objectives of the second objective are:
