Abstract: The present paper deals with the diurnal variation of some physico-chemical properties of Sapana dam water, which is situated about 8 kms. East of Betul city (M.P.), has been studied during January 2019. The parameters studied include Temperature, Transparency. pH, Total Alkalinity, Free CO2 Total Solids (TS), Total Dissolve Solids (TDS), Total Hardness (TH), Dissolve oxygen (DO), Chlorides, Nitrites, Nitrates, and Phosphates. The work was carried out at an interval of four hours during a twenty-four hours schedule commencing from 6.00 a.m. of 04th Jan-2019 to 2.00 p.m. of the next day. It was observed that the values of Temperature, Dissolve oxygen (DO) and Chlorides increases in day time and decreases in night whereas Total Alkalinity increased in night while decreased in day hours. The Free CO2 was recorded nil at day time. Similarly, the Dissolve oxygen exhibit a positive relationship with water temperature whereas there is an inverse relationship of Nitrites and Nitrates with water temperature was found. The other parameters did not exhibit any fixed pattern of variation.
