Hydropower has been the main source of energy for Norway for more than 100 years, enabling industrial development, wealth creation, lighting and heating. However, the effect of hydro-peaking on fish can represent an important issue. This paper looks at the challenges for the lifecycle of Atlantic salmon (Salmo salar) and trout (Salmo trutta), the dominant species in Norway’s anadromous rivers. Discussed here is a study to assess flow, and ensure acceptable flow variations in a regulated river where a peak load hydro plant is in operation.
