The dynamics of Macroinvertebrates distribution and abundance in relation to Physico-chemical characteristics i.e. water temperature, air temperature, pH, transparency/turbidity, current velocity, water discharge, channel morphometry of the stream were observed. All the characteristics were monitored fortnightly over a period of three months (January -March, 2010). Physico-chemical characteristics showed little variation throughout the sampling occasion as a result of the persistent dry hot

... on. A total of 119 Macroinvertebrates were collected and 2 phyla identified, (Arthropoda and Mollusca). Phylum Arthropoda consisted of only one class, Insecta had 3 individuals i.e, Dystiscus, Aeshnidae and Neoperla.
