The Mahanadi River Basin, rising in the state of Chhattisgarh is an important river especially in the state of Odisha. Upstream of the basin experiences periodic droughts in contrast with the regular flood events in the downstream. The increasing rate of global surface temperature is having significant impact on local hydrological regimes that leads to the assessment of water resources potential resulting from the climate change impacts. This work was intended to determine the climate change in the Mahanadi Basin through statistical analysis of historical climate trends using Mann-Kendall test and Sen’s slope estimator test. Statistical trend analysis has been done to analyze the trend using Mann-Kendall test and Sen’s Slope Estimator test has been used to find out the magnitude of the trend. Trends in rainfall (1959-2015) and temperature (1995-2014) in districts of the Mahanadi River Basin were assessed using the two methodologies. Out of the nine stations of rainfall, the significant trend of annual precipitation was found in ‘Ghorari’ and ‘Nandaghat’ and all other stations don’t experience any significant trend. The negative slope arises in the station of Raipur, Saradihi and Sheorinarayani. All the stations experience an intensive rainfall in the month of July and august and minimum precipitation in the month of June and September.
