摘 要：Temporal variability in some water quality parameters were investigated through field test and laboratory analysis in Cole Mere over the summer months(June,July and August) of 2013.A total of 10 sites were selected(within the lake) and sampled at approximately month *** surface water temperature recorded in June,July and August samplings were 14.1°C,21.9°C and 18.2°C *** differences in the mean temperature were statistically significant(p=0.001).Mean Chlorophyll a concentrations were 9.3 μgl,15.2 μgl and 39.8 μgl for June,July and August respectively and the differences between the months were also statistically significant at p=*** observed temporal variability and elevated summer chlorophyll a concentrations are clear indications of eutrophic ***,no significant differences were recorded with regards to p H and dissolved oxygen between the months.
