Lake eutrophication is directly a function of elevated productivity linked to the influx of excessive amounts of nitrogen, phosphorus and sediment. In the vast majority of cases nationwide, inadequate or improper stormwater management is the root cause of this non-point source pollutant loading. Although lake communities and lake managers understand this relationship, they are often at a lost understanding how to quantify this loading and identify, select and implement the correct stormwater management options needed to address and minimize this loading. This is especially true when it comes to discerning how and where to implement green infrastructure stormwater management practices.
This ½ day class begins with a basic an overview to the hydrologic and hydraulic principles of stormwater runoff and management to meet quantity, rate and quality control goals. Participants will then be instructed on how to make use of some relatively easy to use, public domain models and tools that lake managers can use to compute runoff pollutant loads and runoff volumes. The class will then be provided with examples, backed by case-studies, of the application of green infrastructure stormwater management practices suited for lake communities. These will range from small-scale (single lot) applications to large, community-based regional applications. Basic design and construction specifications, as well as maintenance requirements will be presented and discussed for each of the more commonly implemented green infrastructure stormwater management techniques used in lake communities.
