The Lower Ganga Canal originates from the Ganga River at Narora, located in the Bulandshahr district of Uttar Pradesh. It runs primarily through the western and central parts of the state, with several branches and distributaries extending across different districts. The canal is designed to carry water over long distances, supplying irrigation to some of the most agriculturally productive regions of Uttar Pradesh, including districts such as Meerut, Muzaffarnagar, Ghaziabad, Hapur, and Aligarh.
The canal system has a total length of approximately 1,000 kilometers, providing water to thousands of hectares of land in the state. The canal system’s complex network includes main canals, sub-canals, distributaries, and minors to ensure that water is evenly distributed across vast agricultural lands.
2. Design and Construction
The Lower Ganga Canal is a large-scale irrigation project that involves advanced engineering and design to ensure efficient water flow and distribution. The construction of the canal system involves the following features:
- Canal Bed and Embankments: The canal has a well-constructed bed and embankments that help control water flow and prevent erosion. The embankments are reinforced to manage high water levels during the monsoon season and to reduce the risk of flooding.
- Hydraulic Structures: The canal system is equipped with hydraulic structures such as regulators, sluice gates, and weirs that control the flow of water, regulate the release of water from the canal, and ensure that irrigation reaches the intended areas.
- Aqueducts and Bridges: Several aqueducts and bridges have been constructed to allow the canal to cross natural obstacles such as rivers and highways, ensuring the continuity of water flow without disruption.
- Distributary Networks: To maximize the reach of the canal, a network of distributaries and sub-canals branches off from the main canal, ensuring water is distributed to the furthest corners of the irrigation area. These distributaries are often equipped with gates and structures that ensure equal distribution to all sections of farmland.
3. Capacity and Water Supply
The Lower Ganga Canal has a substantial water carrying capacity, which allows it to supply irrigation water to large tracts of agricultural land. The canal draws water from the Ganga River, which is the lifeline for millions of people and their farming activities in the region. The canal’s water supply is critical, especially during the dry seasons when rainfall is inadequate.
Over the years, the canal has undergone modernization to enhance its capacity, control, and efficiency. The construction of additional distributaries and improvements in water management practices have helped address regional water shortages and improve agricultural productivity.
4. Flood Control Mechanism
Another important feature of the Lower Ganga Canal is its role in flood control. The canal, with its embankments and regulated flow system, helps to manage excess water during the monsoon season. By diverting a portion of the floodwaters, the canal prevents flooding in agricultural fields and populated areas.
The canal serves as an important drainage system, channeling surplus water away from the fields, reducing waterlogging, and protecting crops from damage. In this sense, the Lower Ganga Canal acts as a flood management tool in addition to its role in irrigation.
