Eleyele Dam water is abstracted by the Oyo State Water Corporation at Eleyele Treatment Works for treatment and supply of   potable water to Ibadan’s people. The dam is exposed to flooding (Adeleru, 2017) and also polluted by human and industrial activities within the metropolis.  This paper assessed the quality of the water samples taken along the course of the dam. The samples were examined for physical, chemical and bacteriological parameters using standard procedures. (APHA, 2005)The result showed a high concentration of Alkalinity, Hardness, Bacteriological, and Heavy Metal Contaminants (Lead and Iron), when compared with the World Health Organisation (WHO) and the Standard Organisation of Nigeria (SON,2007) quality standards for drinking water. The high concentration of Contaminants calls for great attention because inadequate water treatment before human consumption   could result in the bioaccumulation of heavy metals and result in a public health concern.The study recommends that the dam should be protected from flooding, human and industrial activities. Proper and adequate water treatment should be ensured before supply to the metropolis.
