Abstract

The algae composition and physico-chemical parameters of Awon Reservoir were investigated for a period of four months wet and dry seasons this was done to examine the effect of seasonal variation on phytoplankton The algae comprised a total of twenty-two species belonging to four divisions bacillariophyta chlorophyta euglenophyta and cyanophyta Navicula meniceculus Gyrosigma scalproides Closterium archerianum and C dianae were the dominant species The physico-chemical parameters determined were higher in the dry season than wet season The values of physico-chemical obtained fell within the maximum allowable limit set by United Environment Protection Agency
