In order to gauge how to best prevent eutrophication from occurring, specific sources that contribute to nutrient loading must be identified.

Ploughing in agriculture and development are activities that contribute most to nutrient loading.

Our explanation highlights the consequences of excessive nutrient loading and the resulting low oxygen levels in local coastal waters.

(By nutrient loading, we mean exposing water to sewage, fertilizer, chemicals or other pollutants.)

Because Lake Winnipeg holds a considerable small volume of water, the water quality is determined by manmade structures and low nutrient loading.

Water quality and enforcement programs face complex challenges, from nutrient loadings and stormwater runoff, to invasive species and drinking water contaminants.

Livestock effluent contains valuable nutrients, but the misapplication of these materials can lead to serious ecological problems, such as nutrient loading.

Inputs to the model are: lake hydrology, nutrient loading, dimensions and sediment characteristics.

"Every time we flush our toilets, fertilize our lawns, gardens and fields, or wash our cars we contribute to the nutrient loading of the lake."

These practices will help to reduce nutrient loadings downstream, improve water quality, and restore habitats while still maintaining agricultural productivity.
