Minor Irrigation Projects have great utility in Bihar because of the following reasons: — Minor Irrigation Projects provide irrigation in comparatively very short duration on very small investment. Minor Irrigation Projects are suitable in exploiting abundantly available small catchments with their network of natural drains, in the State. High patches of land in the command of a Major Irrigation Project don't get irrigated. Such patches of land could be provided irrigation with the help of a suitable type of Minor Irrigation Project. Thus a Minor Irrigation Project works as complimentary as well as supplementary project to a Major Irrigation Project.
