Ground water is often developed without proper understanding of its occurrence in time and space and its continuous withdrawal over-exploitation and contamination. Water level fluctuations of the observation wells between decades over an area indicate the net changes in the ground water regime and it is an important parameter for planning sustainable ground water development. The present study was conducted at Dept. of Agro- Meteorology to find status of Ground Water in Hisar district for two decades i.e. from 1996-2017. The groundwater data were analyzed for their long - term pattern, and were interpreted graphically to understand the dynamics of the groundwater level and fluctuation. The main objective of this study was to investigate the temporal trends in annual and seasonal groundwater level and fluctuation in Hisar District. The spatial variation of Ground Water was analyzed using Arc GIS software by compilation of existing data, generation of GIS database (shape files), interpolation, categorization, mapping and interpretation. During the pre-monsoon season the groundwater level varied from 2 meters to 12 meters in depth and during the monsoon season it was found from 2 meter to 10 meters below ground level (bgl) during 2017. Noticeable spatial variations were observed in average Ground water level of pre-monsoon & monsoon in the Narnaud and Agroha blocks. The maximum rise in the water level was observed at Agroha Block whereas maximum decline was at Adampur Block.
