Cauvery flows for a distance of 475 miles from Coorg hills in Karnataka to Bayof Bengal in southeastward direction. It travels for ~100 miles inside Karnataka. KN constructed an artificial channel of 72 miles inside KN to divert water to more areas. In TN, it travels nearly 320 miles baring Pondicherry. Karnataka built two huge dams namely Krishrajasagar(KRS) and Kabini for 100 miles whereas TN has a major reservoir in Mettur and a comparatively smaller but ancient Grand Anicut(Kallanai - built ny Karikalachola 1700 years ago) for 320 mile lengthy river.
Water is stored in KRS and Kabini reservoirs in full throughout the year and release less quantity than the allocated share. Whenever there is heavy rainfall in water catchment area (i.e.Western ghats), excess water is suddenly released flooding the whole heavily cultivated plains of TN forcing people to live in distress. Karnataka uses TN just as the drainage channel to let excess water.
Now readers can tell us who is acting as the big brother and who suffers?.
