The distribution and abundance of microalgae in the Rivers are controlled by a wide range of physical, chemical and biological factors. The study was aimed to determine the physico-chemical properties as well as the relative abundance and species diversity ofAlgae in Gundutse River Kano, Northern Nigeria for a period of 3 month (April – June, 2019). Surface water sample for the study were collected from three (3) different sampling (A, B and C) sites based on the depth of the water and analysis of water was conducted either insitu or transported to the laboratory for further analysis. The physicochemical properties of the water were determined using standard method while the algal species were determined and identified using microscope. The result of physicochemical properties of the water showed that the temperature, pH, turbidity and electric conductivity ranges from 25.13 to 25.800C, 7.3 to 7.7, 140 to 155 NTU and 617 to 628μs/cm respectively. The average values of nitrate, phosphate, Dissolve Oxygen and Biochemical Oxygen Demand (BOD)of the water ranges from 1.80 to 2.13 mg/L 1.0 to 1.16 mg/L, 3.73 mg/L to 4.10 mg/L, 1.96 to 2.23 mg/L respectively. From the result a total of twenty (20) different algal species were identified belonging to three (3) different classes namely; Chlorophyceae (40%), Bacillariophyceae (50%) and Cyanophyceae (10%). It is concluded that the occurrence and abundance of green algae species in the river is closely related to the physicochemical characteristics of the water.
