Manitoba Prairie Lakes: Mass balance budget for nutrient management at Pelican Lake, Manitoba
While the water quality of many prairie lakes is monitored and the extent of the eutrophication—and associated negative consequences—generally understood, information on the specific nutrient sources and in-lake processes is often insufficient to identify specific management options.
This study sought to conduct a water and nutrient mass balance, identifying the variance and relative importance of different nutrient sources and internal lake processes for a lake that could be used as a general model for other prairie lakes. As with many other shallow prairie lakes, the eutrophication of Pelican Lake has become increasingly pronounced over recent years.

On World Wetlands Day, the world’s 'Great Lakes' are Exhibit A for why wetlands matter: Ted Lawrence
It might not be grabbing headlines around the globe, but tomorrow's U.N. World Wetlands Day matters. Wetlands across the globe provide many services, from improving water quality and protecting from floods and droughts, to providing habitats for countless flora and fauna, much of which we depend on. More broadly, World Wetlands Day accords us a rare and precious opportunity to celebrate North America’s abundant — but certainly not infinite — freshwater supplies.
