The present study attempts to determine groundwater recharge of the two over exploited blocks of Karur district in Amaravathy basin viz., Aravakurichi and K. Paramathi by water table fluctuation method. Rainfall data of eight rain gauge stations for 30 years (1982-2012) and water level data of twenty three stations were collected from the office of State Ground and Surface Water Resources Data Centre, Tharamani, Chennai for analysis. The rainfall occurs in four distinct season’s viz., NE monsoon, SW monsoon, summer, winter are 54.1%, 26.58%, 17.57% and 1.73% respectively. The water table fluctuation varied from 0.2 to 3.1 m in SW monsoon, and 0.4 to 6.6 m in NE monsoon in Aravakurichi block, whereas in K. Paramathi block groundwater level fluctuation varied from 0.1 to 3.7 m due to SW monsoon, and 0.4 to 5.4 m in NE monsoon. It was observed that the recharge percentage in Aravakurichi block varied from 5.25% to 16.74% in Aravakurichi block and 5.69% to 16.20% in K. Paramathi block.
