Abstract: Due to high spatial variation of rainfall in Mahanadi basin, drought is dominantin some districts (5 districts of Chhattisgarh and 9 districts of Odisha). Also some districts face water logging problem, which are near to coastal parts.Hence, effective water management strategies require to manage these problems in Mahanadi basin.Water accounting plus (WA+) is a framework whichgive overall idea about water balanceofriver basins.WA+ framework consists of eight factsheets.According to the analysis of rainfall data for the periods 2003-2014, the year 2012 has been identified as average year. Thus, this paper shows the evapotranspiration (ET) sheet for a period of 1 year i.e. from June 2012 to May 2013. The results indicate that out of 137.5 km3/year total ET 92.8 km3/year is non-beneficial and 44.7 km3/year is beneficial ET, which is based on whether the ET is meeting the intended purpose or not. It further reports on the separation of ET into evaporation (75 km3/year), transpiration (52.5 km3/year) and interception (10.1 km3/year). All datasets are from satellite data product which are freely available and accessible
