The purpose of these tests is to be able to follow the evolution over time of the quality of the lake water. Tests have been carried out at two stations in Grand Lac Rond since 2011. Clarity tests using the Secchi disk are carried out every two weeks during the summer. Samples for physicochemical tests are taken once a year during the summer and are sent to the RSVL laboratory of the Quebec Ministry of the Environment for analysis. The results are on the Ministry's website in the RSVL section. Click here to go there.
