The State of Karnataka covers an area of 190498 km2 with a population of 61 million. Geologically, the state is covered by Archaeans, Proterozoic sediments, basalts of Deccan Trap Province and alluvium of Recent age. The Western Ghats, Karnataka Plateau and Coastal Landforms are the major geomorphic features of the state. In spite of seven river systems and 36,753 tanks in Karnataka, 67 percent of the land falls under dry tracts. Estimates are available for the average yield of river basins of the state. The quantum of water available in a water year for utilization appears to be beyond assessment because of erratic behaviour of rainfall and Inter-State River Water disputes. The poor management of catchment area, siltation of water bodies, poor management of distribution network, abuse and misuse of resources are the other factors for the stressful situation. The impact of climate change on the water resources cannot be ignored. To cater to the needs of growing population, the available water has to be protected, improved and managed efficiently. The approach should be holistic including soil specific agricultural practices, judicious use of water and awareness of stressful situation of water resources. Since the Krishna and Cauvery basins are “Closed Basins,” the riparian states should have positive approach in the interest of the people.
