Researchers raised the water level in Lake 979 and its bog to simulate flooding for hydroelectricity generation. Two issues concerning hydroelectric developments were the production of methylmercury (toxic to humans, as well as zooplankton and fish) and the release of greenhouse gases that can contribute to climate change. At IISD-ELA, we have a long history of research on the effects of dams and reservoirs—and Manitoba Hydro has been a longtime partner. In all cases, we ultimately want to provide advice on how to design and manage reservoirs to minimize their impacts on the environment.
