There is lot of misinformation spread in media abt TN Cauvery water use

2. TN is opening ~5000cusec to Delta 1/n 3. Using TN NEM monsoon as excuse is misleading because Mettur local catchment receive less NEM monsoon than Delta. TN need water in Mettur for drinking water.

Talk of delimitation is alarming for TN. In 1957, TN had 8.3% of seat in Lok Sabha(41/494), in 1976 TN had 7.2% of seats in Lok Sabha(39/543). If Centre come with 1 person 1 vote, the delimitation will reduce TN share to 5.5%. That is removing 24% of TN current representation 1/3

Argument of 1 person 1 vote can't be accepted in India, becoz in 1976, it is the govt of India that "mandated" states to control the population, froze the percentage of representation. Now, centre can't come and say April fool to the state that followed the mandate 2/3
