The left canal (Lalbahadur Shastri canal) is long with maximum 311.5 cumecs capacity and irrigates of land in Nalgonda, Suryapet, Krishna, West Godavari and Khammam districts. The project transformed the economy of above districts. 54 villages (48 in Nalgonda and 6 in Guntur) were submersed in water and 24,000 people were affected.
