Comparative Limnological Studies of Nnamdi Azikiwe University (Unizik) and Amansea Streams in Awka South L.G.A., Anambra State, Nigeria

The limnological studies of Unizik and Amansea streams, Awka South Local Governments Area, Anambra State, Nigeria, were carried out using standard methods. The mean water temperature, dissolved oxygen content, transparency and pH were 26.330C, 2.75 mg/l, 49.10cm and 7.80 respectively, in Unizik Stream. For Amansea Stream, the values were 26.580C, 2.40mg/l, 35.87cm and 7.70, respectively. The mean BOD, Alkalinity, water depth and water current values recorded in Unizik stream were 16.00mg/l 119.70mg/l,58.25cm and 0.45m/s respectively, while in Amansea Stream the values were 11.50mg/l, 111.35mg/l, 59.43cm and 0.39/s respectively. The physicochemical parameters of the two streams vary spatially. Unizik and Amansea streams exhibited features that are typical of streams in tropical environment. The low dissolved oxygen content, high biochemical oxygen demand and low alkalinity values indicate that the water bodies are unsuitable to support aquatic life.
