Limnological Studies of Bosso Dam and its Tributaries in Minna, Niger State, Nigeria.

Abstract

The physico-chemical parameters of Bosso Dam were analyzed weekly for a period of six (6) weeks from 29th October, 2009. In all, six (6) stations were identified within the dam. The physico-chemical parameters assessed were: temperature, dissolved oxygen, pH, alkalinity, hardness, conductivity and transparency. The results obtained from the analysis revealed slight variations in most parameters. There was no significance difference p>0.05 in pH regardless of stations and weeks. But significance p>0.05 were observed in dissolved oxygen, nitrate, temperature, conductivity, hardness, alkalinity, biological oxygen demand, transparency, in respect regard to stations. These variations could be due to influx of organic waste deposited by man. The physio-chemical parameters observed, indicated that most of them fall with the recommended range or standard by the Federal Ministry of Environment (FMENV,2000).
