The Lower Ganga Canal is an important irrigation canal in northern India, primarily serving the states of Uttar Pradesh and Bihar. It was constructed in the 19th century to divert water from the Ganges River to support agriculture in the region, enhancing crop production and ensuring water supply during dry seasons. Spanning approximately 570 kilometers, the canal plays a crucial role in the irrigation system of the Ganga River Basin. It helps in managing water resources effectively, benefiting millions of farmers by providing a reliable source of water for their fields and contributing to the overall agricultural economy of the area.
