Aspects of 25 years of Canadian experience with stormwater management lakes

The experience of older stormwater management (SWM) lakes in Canada shows that, even if peak flood reduction or effluent objectives requested by guidelines can be achieved, future public perceptions of lakes as an amenity were sometimes overestimated, and municipal rehabilitation efforts to avoid complaints can, in some situations, become significant. Analysis of limnologic performance and review of problems of older lakes was used in recent projects for the development of improved solutions for future lakes and a public consultation based on more realistic predictions.
