The contamination of water bodies has become a worldwide issue. Water samples collected from Ogbia axis of Kolo Creek at Imiringi, Emeyal and Otabagi were analyzed for heavy metals concentrations. The samples were analyzed with atomic absorption spectrophotometer (AAS). The results showed that lead varied from 0.729±0.10 - 1.034±0.11 mg/L, copper varied from 0.611±0.03 - 1.136±0.12 mg/L, cadmium varied from undetected - 0.0012±0.00 mg/L, mercury was undetected in all the stations, nickel varied from 0.069±0.01 - 2.413±0.16 mg/L. The values for chromium varied from 0.711±0.11 - 1.360±0.22 mg/L, iron varied from 1.321±0.21 - 2.348±0.41 mg/L and zinc varied from 1.344±0.13 - 2.461±0.42 mg/L. Evaluation of the water using some pollution indices indicted that the water has either been contaminated or polluted by individual heavy metal except mercury that was not detected. The general observation made based on result findings revealed that the water is not fit for human consumption. Therefore adequate measure should be put in place by the different governments (local, state of federal) to preserved this water body from complete deterioration, since it is a mojor source of water supply for the Ogbia tribe of Bayelsa State, Nigeria.
