Step 1: Traditional Water Storage.
Tank irrigation is a popular method in Karnataka because the region has a rich history of building tanks and reservoirs for water storage. These tanks are filled during the rainy season and used for irrigation during dry periods.
Step 2: Efficient Water Use.
Tank irrigation ensures efficient water distribution to agricultural fields. Tanks are well-suited for regions with uneven rainfall, as they store water from monsoon rains and provide a reliable source for irrigation during drier months.
