Hydroelectric developments and fish
All new hydro projects entail environmental studies, mitigation and compensation measures, and several years of follow-up studies after their commissioning. The environmental and fish-related issues involved differ for each project.
To give an idea of the variety of issues covered by Hydro-Québec through its studies on fish or the developments built for fish throughout Québec, a few technical reports and their abstracts are presented below. There are also summaries of environmental follow-up studies, along with a few studies that do not fall within the usual scope of hydropower projects. The studies are grouped by location. For the complete list of aquatic wildlife and environment studies carried out by Hydro-Québec, visit the environment and communities documentation centre.
