Abstract

A study of water quality condition of Digil Dam Mubi North-eastern Nigeria was carried out for the period of July to September 2008. Five sampling sites were selected for the research. The stations included the inlet site towards the eucalyptus trees; station (A), the entrance gate; station (B), opposite to the second station; station (C), the spill way channel; station (D), the middle of the Dam; station (E). Data were collected in triplicate for temperature, pH, conductivity, dissolved oxygen, total dissolved solids, alkalinity, salinity, and phosphate concentration using standard methods. The result showed variations in the monthly and station to station values of all the water quality parameters tested. Despite this variation the values were tolerable range of the majority of tropical fresh water fish species.

Key words: pH, conductivity, dissolved oxygen, alkalinity, salinity.
