Dont know u will read this. If due to the income and resources are the concern for Salem division why you are asking for Mullaperiyar Dam? Completely on Kerala land and Kerala not even drawing a single drop from that Dam.
Kerala never said they wont give water to TN. Only demand is construct a new Dam on the same place and takse as much as water you want. Even if the Dam is is good strength , you cant ignore the fear of life of 40 laks people living in the vally. Supreme Court order was based on panel people from North india and TN they studied the Dam. Only one member in the Panel from Kerala and He opposed the panel findings. Rest everybody get paid by the TN for political movement. Try to understand central government is ready to fund for the new Dam and why TN is opposing it. TN is not losing water , not losing money...
In case the Dam is broken , How TN going to get water further? Even if you are not making a new Dam how long you can with and old Dam? Tomorrow the Dam is broken then atlest some thousands will die in Kerala, Then due to non-availablity of water will make atleast 4 districts of TN become suicide points for TN farmers...It is suicidal for both Kerala and TN...New Dam is the only solution, Thousands die in Kerala and TN nothing will happen in Chennai and New Delhi(Supreme Court).
