Toews Environmental Nutrient Budget Kerr Lake

To assess causes of severe cyanobacteria blooms in Kerr Lake and to inform possible corrective actions, water samples for chemical analysis and phytoplankton taxonomy, as well as in situ measurements of stream discharge and water quality, were collected by and for the Little Saskatchewan River Conservation District. Sampling was conducted in winter and through the open-water season in 2018 in Kerr Lake, its outflow and six inflowing streams. Toews Environmental Consulting & Aquatic Sciences analyzed and interpreted the data and calculated whole-lake nutrient budgets including external and internal phosphorus loading.
