Description: The Holland Marsh basin comprises approximately 3,000 ha of intensively farmed histosols in flat, low-lying lands, north of Toronto. In order to prevent flooding, the Marsh is bounded by earthen dykes and canals. A pumping station discharges the drainage water from the basin to Lake Simcoe. Due to the high value vegetable crops planted in the Holland Marsh, there are high rates of fertilizers and other agro-chemicals applied to the cropland, some of which is pumped with the drainage water to Lake Simcoe. This has led to long term eutrophication of the Lake, and destruction of the freshwater fish species which inhabit the Lake. This presentation will cover the drainage and water quality impacts of the Holland Marsh, and the efforts made to develop improved drainage practices, to reduce nitrogen and phosphorus loadings in the drainage effluent. The goal is to help achieve the target nutrient loading limits set by the Lake Simcoe Region Conservation Authority.
