Variations in the Physico-Chemical Parameters of a Natural, Tropical, Rainforest Lake

A study of the physico-chemical parameters of Agulu Lake was made from January to December 2003. Except for surface temperature, the other parameters were markedly season-dependent. Conductivity, total residue, DO, alkalinity, turbidity, calcium, N-NO3, P-PO4 values were higher in the rainy than the dry season. Conversely, pH, visibility and free CO2 were higher in the dry season. There was no significant seasonality in surface temperature.
