Can a hartal prevent a dam from breaking?

Tomorrow there will be a hartal announced by some political parties in four districts which will be washed off if Mullaperiyar dam breaks. Is this the right way to prevent a dam from breaking? Mullaperiyar is an inter-state water issue. Tamilnadu needs water for irrigation purposes. Kerala people always agrees to give water to Tamilnadu, because this state gives Kerala all the foodstuffs they eat. But if the dam breaks, 35 lakhs of people in Kerala will be washed off and 5 districts in Tamilnadu will be dried off. So the only solution to this problem is a new dam. The old dam should be decommissioned as early as possible. Rulers of both the states come to a table for talks and an agreement for water supply for the future must be signed with the proposal of construction of a new dam. This will help both the states from a big tragedy.
