The most representative class in terms of species richness was Dinophyceae
(2species) and dominated by Ceratium hirudinella. Cyanobacteria had 13 species and was dominated by Microcytis
flos aquae, Baccilariophytes had 10 species, Chlorophytes had 15 species, Cryptophytes (4 species), Chrysophytes
(2 species) and the least of the species was Euglenophyte as it contributed with lower biovolume values. The total
biovolumes of the phytoplankton species including Microcystis Flos aquae and Oscillatoria aghardii increased
progressively following the increase in temperature over the summer months with a mean level of temperature was
17°C, pH-7.72; conductivity of 0.199ms/cm and Dissolved Oxygen, 87%. When the lake’s chemical components,
phytoplankton composition and phytoplankton biomass were compared with international technical standards for
measurement, including the World Health Organisations’ standard for water quality and the EC Directive for good
quality water, the results indicated the lake to fall within the mesotrophic-eutrophic status. At the time of this
study, the lake was not susceptible to generating algal blooms
