 In 1985, LSEMS identified phosphorus inputs from both urban and rural sources as the leading cause of the decline of Lake Simcoe's water quality and coldwater fishery.The LSEMS Team seeks provincial funding in 1986 for programs and services aimed at reducing the amount of phosphorus entering water courses from both urban and rural sources to stop contamination and deterioration of the lake.This year, the Conservation Authority is renamed the Lake Simcoe Region Conservation Authority to better reflect its area of service.
