Major means of irrigation in Bihar

Canals

Canals are the main means of irrigation in Bihar. There are 11 major canals and their sub-branches in Bihar, which are spread over different districts. The canals in Bihar can be classified into two major parts –

1. Regular canals – Those canals in which water is stored throughout the year are called regular canals. Most of the canals in northern Bihar are continual canals, drawn either directly from rivers or from artificial reservoirs of dams built on them.
2. Seasonal canals (non-flowing canals) – Those canals which have been taken out from the rivers, but in these, the excess water of the rainy season flows from the rivers and very little water is available in them during the spare time.

Tube well

Tube wells are another major source of irrigation in Bihar. The geographical structure of the Gangetic plain in Bihar is like that of the Pataltod well, due to which underground water is found at less depth in this area. This tubewell creates ideal conditions for irrigation.

Talab (Pond)

Irrigation by ponds is an old method, which is adopted in almost all the districts in the state of Bihar. Ponds are both natural and artificial. Water is stored in these, which are used for irrigation.

Well

Apart from this, wells have been the main source of irrigation in Bihar since ancient times. The groundwater level in the Gangetic plain is high enough. At some places, after digging 10 feet, the source of water starts to be found. Dhekli and Rahat are used to draw water from wells, which reach the fields through drains.
