Environment and Climate Change Canada (ECCC) uses satellite remote sensing to monitor lake-wide water quality indicators across Canadian inland waters. Remote sensing provides a cost-effective solution to obtain frequent lake-wide water quality observations in support of lake science and inland water quality management on an on-going basis. The datasets presented in the EOLakeWatch interactive web-tool provide long-term satellite-derived monitoring of water quality indicators, contributing to programs such as the Lake Winnipeg Basin Initiative and Great Lakes Nutrient Initiative.

The EOLakeWatch interactive data portal contains daily current and historical (back to 2002) satellite-derived algal bloom indices (extent, intensity, and severity) throughout the June to October monitoring period. In addition, the portal contains daily satellite-derived chlorophyll-a map images for Lake Winnipeg, Lake of the Woods, and Lake Erie.

I am a 27-year-old girl. I have worked in a charity organization for a long time. I have no one. I lost all my families in the last war. Now the situation in Afghanistan is very bad.
