  Author(s): Takele Shitaw*, Lammessa Berisa and Berhan Asmamaw
  
  Water resource contamination is still a major concern in several regions of developing countries especially in sub-Saharan countries in which polluted waters pose serious risks to human health and the environment. The research was aimed to evaluate the current water quality status of highland Lakes (Ardibo, Logo and Tana) of Ethiopia in different season and to identify potential pollution sources sites. Physico-chemical water quality parameters have been determined by taking duplicate samples from three sampling sites of each lake and the results were compared with WHO and FAO standards. The result of the study indicates nutrients concentration to be Alkalinity (428, 269.945, 109.935 mg/L), calcium (31.542, 46.873, 77.12 mg/L), chloride (89.165, 77.5, 40.125 mg/L), magnesium (94. 755, 93.165, 39.396 mg/L), NH3 (0.418, 0.184, 0.6493 mg/L), NH4 (0.433,0.145, 0.753 ..
