Includes bibliographical references. "Painter et al. (1989) examined the water clarity problem in Cootes Paradise and concluded that several actions would be necessary to improve water clarity and reduced loading from the Dundas STP was one of the recommendations. In 1988, the Dundas Sewage Treatment Plant (STP) reduced its phosphorus solids loading and suspended to Cootes Paradise by installing sand filters. Cootes Paradise was revisited in 1990 to determine if water clarity had improved. Secchi disc transparency, seston, and chlorophyll at the main open water station and at West Pond, the direct recipient of the STP effluent, were no different from past years. In fact, STP suspended solids and phosphorus loadings had increased slightly in 1990 compared to 1987. Water clarity appears to be more a function of incoming turbidity on Spencer Creek and resuspension processes in Cootes Paradise than algae stimulated by phosphorus loading from the STP"--Abstract.
