Abstract: It is known fact that India has a very large population and different studies show that it will continue to rise. The precipitation in India is extremely conflicting in mainstream varieties. The normal yearly precipitation for India has been assessed at 1,143 mm for the actual surviving of the nation, there is a good requirement for actualizing and arrangement of watering system procedures for the time being, and in the future. The present condition of canal and present cropping pattern, water is insufficient for the designed command area. In this method both discharge & crop requirement is considered. Hence for improving the irrigating capacity of canal, designed cropping pattern should be strictly followed. Increased pipe outlets should be reduced to its design size. Also uncontrolled pipe outlets should be controlled by suitable controlling methods for determining the sufficiency of water distributory. In order to determine the sufficiency of water, a distributory (D-65) in Hemavathi canal system is considered which runs for a length of 26.675 km having command area 4703.08 Ha. Crop water requirement by Duty method & Modified Penman’s Equation of discharge through outlets is used for determining sufficiency of water. Climatic data for Modified Penman’s method is collected for a period of 5 year from K.R Pete Hydrometer logical station in this connection
