Abstract This study was conducted on the potential significance of nitrogen, phosphorus and micronutrients in limiting planktonic algal growth in Lake Ontario and its major tributaries. Standard algal assay procedures were used. Samples of the open waters of Lake Ontario and Niagara River waters collected during the spring showed phosphorus limitation. By late summer these waters showed both nitrogen and phosphorus limitation. Genesee and Oswego Rivers showed, in general, nitrogen limitation. Samples of the Black River waters showed both nitrogen and phosphorus limitation.
