| Annex 3 of the Great Lakes Water Quality Agreement calls for the development and implementation of phosphorus control programs and measures to reduce algal biomass and to eliminate nuisance conditions, especially in Lakes Erie, Michigan and Ontario. The primary objective of reducing phosphorus loadings to the Great Lakes was to control algal abundance and species composition. Based on TP trends observed in the GLNPO long-term monitoring data and Environment Canada, for all five lakes, there has been a decline in spring total P over the last 3 to 4 decades. At the same time, green slime conditions have reemerged in the nearshore zones and are reported in various places in all Lakes except Lake Superior. This talk will discuss the chemical and biological conditions observed in the biological nutrient depleted offshore and nutrient enriched nearshore zone. |
