Hydropower and water management dams have been known to serve as barriers to fish migration. With fewer fish migrating throughout the watershed, this changes the fish community structure and also the productivity of the system. Very few fishways have been evaluated to determine if they are helping to pass target fish. Cooke and his team tested how effectively the Vianney-Legendre vertical slot fishway helped to pass freshwater fish with the hopes of identifying design criteria that could be incorporated into fishways at dams across Canada.
