Details

This project investigated small-scale hydroelectric power (HEP) schemes with the aim of improving understanding of the environmental effects of HEP schemes in rivers. The study looked at changes in fish communities from run-of-river HEP schemes compared with a set of control sites without hydropower across a range of river types and locations. The research showed that the impact of these schemes on fish is limited, although the small number of samples means that subtle changes may not have been detected.
