Criticality Level Priority
Rationale Climate change is projected to increase water temperatures, which will impact the migration and health of fish through the Basin. What are the projected impacts and can they be alleviated by changes in operations (e.g., by providing thermal refuges for fish during periods of warm water to increase survival of returning adults)?
