Ground water (GW) is as precious as oil pool and needs judicious exploitation for sustained hydro-ecological equilibrium of an area. This requires accurate estimates of prevailing GW recharge components using simpler procedures. In the present study attempt has been made to quantify GW budget of a 358.0 ha watershed comprising predominant wastelands. Water table fluctuation method was applied along with GW parameters/norms prescribed by Central Ground Water Board for the local area. The net annual draft through 60 shallow dug-wells was predicted as 1.89 million cubic meters (MCM), while the net annual recharge came around 1.0191 million cubic meters leaving a GW balance of 0.8346 million cubic meters. Maximum GW drafts (Gross value; 0.81 million cubic meter) were experienced in non-monsoon period. The major fraction of annual recharge (Gross value; 0.43 cubic meters) was contributed from monsoon rainfall. The existing stage of GW development was found to be safe and still having for its further enrichment. Based on detail analysis and interpretation of factors influencing recharge, infiltration method is used to estimate recharge rates by using readily available data (rainfall, runoff). Other estimate methods are difficult to be applied due to the limited information available in the study area. The research has been done by using the infiltration method for the ground water recharge in specific area i.e. watershed area comprising Yamuna of Shankargarh.
