Today, 183 homes and cottages border the lake.The lake was found to be approaching a state of eutrophication in the 1970s. The lake's sanitation was improved, following the installation of a sewer system in Dunham in 1986–87, which replaced the septic tanks used previously. Additionally, the lake's condition ameliorated following the re-vegetation of the lakeshore, restoration of ditches, and the installation of sediment sensors and catchment basins by the city of Dunham in collaboration with the Association pour la protection de l’environnement du lac Selby (APELS).In 2007, Selby Lake, along with other lakes in Quebec, were found to be contaminated with blue-green algae.Selby Lake was mentioned in season 2, episode 12 (The Choice) of the American television drama series Homeland.
