The groundwater is a dynamic and replenishable natural resource but in hard rock terrains its availability is of limited extent and essentially confined to the fractured and weathered horizons, which points toward efficient management of groundwater in these areas. The behaviour of groundwater in the Indian sub-continent is highly complicated due to the occurrence of diversified geological formations. Hence, the groundwater extraction and corresponding recharge studies were conducted at Yarehalli micro-watershed during the year 2016–2017. The results indicated that the groundwater fluctuation and discharge was more in the year 2017 as compared to 2016. The total draft of groundwater was found to be 27, 09, 619 m3, against the total recharge of 1, 80, 462 m3 with the groundwater extractions being 15 times more than the recharge.
