Abstract: With the advancement of drilling technology along with assured availability of electricity ground water extraction for irrigation started increasing. The current study carried out at research farm of Raipur campus of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh facing the same problem. Study is performed with the aim to increase the utilisation of available surface water in the study area carried by diversion canal from one diversion structure (called Bharri dam) constructed on the rivulet in the study area (called Chhokranala). Actual carrying capacity of the diversion canal and other 6 drains in the study area was worked out on the basis of their existing dimensions and grades. Required discharge required to be carried out by the diversion canal and other six drains were also worked out on the basis of drainage coefficient. Based on the comparison of required discharge capacity with actual discharge capacity revised dimensions were proposed to drain out the study command quickly during the heavy rainfall. Total annual ground water recharge from the study area was assessed as 4,01,880 m³, which is sum of ground water recharges through infiltration, return flow due to surface irrigation by diversion canal, return flow due to bore well irrigation and recharge from tank/ponds (67,500 m³, 1,41,800 m³, 1,86,400 m³ and 6,180 m³ respectively).
