Algal bioassays indicated that the waters of Roodeplaat dam are severely eutrophied since algal growth potentials (AGP) of up to 200 mg/l and batch culture algal growth rate of up to 2,2 d were registered with selemastrm capricornutum as test alga. The purpose of the study was to determine the present eutrophication status of Roodeplaat dam and the effect of either increased discharges of secondary treated sewage effluents.
