Field study was conducted to record Diurnal Fluctuations in Physico-chemical Parameters of Goriganga river at Madkot (about 1300 m above the sea level and 231 kms from University Campus) where Mandakni river joins Goriganga river. Some total eight Physico-chemical parameters, such as ambient temperature, water temperature, diddolved oxygen (D.O), free CO2, ph, carbonate, bicarbonate and total alkalinity were monitored at 4 hour interval for a period of 24 hours from 6 a.m. on the 25th of February-2008 to 2 a.m. of 26th of February-2008. The recorded data showed that ambient temperature fluctuated between 9.0C to 20.4C, water temperature 7.0C to 11.0C, dissolved oxygen 11.6 mg/l to 15.2mg/l, ph 7.0 to 8.39 carbonate 4.0mg/l to 5.0mg/l, bicarbonate 132mg/l to 170mg/l and total alkalinity between 138mg/l to 166mg/l. Free carbondioxide(CO2) was completely absent throughout the study period i.e. for 24 hours. In the present study a positive relationship between water temperature and dissolved oxygen was observed.
