In 1977, SEBJ set up an ecological monitoring network in order to evaluate the changes in the environment resulting from the creation of reservoirs in Northern Qu#xE9;bec. This information may later be used to improve the methods of predicting impact and to assist specialists in choosing appropriate remedial measures. Generally, systematic observations are made at stations located either on the three main reservoirs or nearby. Research is mainly concentrated on various physical chemistry parameters, primary production, phytoplankton, zooplankton, benthos and fish. Conventional mathematical analysis was used to reveal the relationships existing between these parameters. The authors present the main changes observed during the first four years the network has been in operation.
