Sample interview questions: Can you explain the process of fish passage and protection in hydroelectric systems?
Sample answer:
- Fish Ladders:
-
Construct fish ladders or fishways to allow fish to bypass dams and continue their upstream migration. These structures consist of a series of pools or steps that gradually elevate the water level, enabling fish to swim over or around the dam.
-
Fish Screens:
-
Install fish screens at the intake of hydroelectric turbines to prevent fish from entering the turbines and being injured or killed. These screens are typically made of perforated metal or mesh and have openings small enough to block fish while allowing water to pass through.
-
Bypass Systems:
-
Incorporate bypass systems into the hydroelectric facility to divert fish away from the turbines and safely release them downstream. These systems can include channels, pipes, or tunnels that transport fish around the dam.
-
Turbine Design Modifications:
-
Design and use fish-friendly turbines that minimize the risk of fish injury or mortality. These turbines often have specialized blades and operating conditions to reduce the likelihood of fish strikes.
-
Fish Habitat Enhancement:
-
Implement fish habitat enhancement measures upstream and downstream of the hydroelectric facility to improve fish populations and provide suitable habitats for various fish species. This can include creating spawning grounds, riff… Read full answer
