Phosphorus modelling and control options

This report provides a complete data record of all water quantity and quality information collected during 1982, 1983 and 1984 for the Lake Simcoe Environmental Management Strategy (LSEMS) studies. During 1982 and 1983 seven water level recorders and thirteen water quality stations were installed to determine discharge and nutrient concentrations for the four largest watersheds of the Lake Simcoe drainage basin. These four watersheds were the Pefferlaw Brook, the Beaverton, Black and Holland Rivers. The Holland River was most intensively gauged and sampled watershed due to it's variability in landuse characteristics and the backwater influences of Lake Simcoe.
