This work assessed the quality of the Adabada Lake in Ihitte Uboma Local Government Area of Imo State; Nigeria. Water samples were collected from sampling point A where residents draw water for domestic use and sampling point B close to shoreline where the Lake has initial contact with runoff. Samples were tested for temperature, turbidity, pH, conductivity, colour, TSS, TDS, DO, BOD, COD, sulphate, phosphate, nitrate, total hardness, total microbial load, total coliform count and Escherichia coli count, using standard methods. Laboratory analysis results obtained for sampling point A and B respectively were :Temperature (28,30),Turbidity (60,69), Colour, (25,29), TSS (54,58), Electrical conductivity (107,112), TDS (125,132), Total Hardness (265,266), Ph (5.8,5.6), Do (8,5), BOD (15,18), COD (3,4) Nitrate (47,60), Phosphate (6,6.9), Sulpahte (260, 265) Total Microbial Load( 14,14.5), Total Coliform Count (3.6,4), Escherichia Coli Count (2.8,3). Correlation analysis between results of the samples A and B show strong positive relationship for variations in A and B (R2=0.9). Water Quality Index analysis show that the Lake has poor water quality (WQI=37) using the Canadian Council of Ministers of the Environment Method. It is recommended that the Lake be environmentally renewed and beautified for aesthetics, recreation, irrigation and uses other than drinking.
