The Water Resources Department of Karnataka manages irrigation, water supply, and flood control across the state. Several departmental wings and Nigams (corporations) work together to achieve these tasks. Each wing has a specific function and supports the development of the state’s water resources. The Nigams focus on implementing projects and managing them efficiently.
