"I will agree if people of Coochbehar give a green signal. Otherwise not. I will agree to it if people of north Bengal want it. I will not allow it to happen at any cost by drying up north Bengal," she said at a panchayat election meeting in north Bengal's Coochbehar district bordering Bangladesh.
"Till I am there I will not allow any atrocity committed or deprivation caused to the people of north Bengal," Banerjee said.
Banerjee had pulled out from the Prime Minister's entourage for the Dhaka trip in 2011 on the issue.
She had earned the displeasure of both the UPA government and Bangladesh for refusing to share Teesta water with the neighbouring country.
The river, which originates in north Sikkim as a trickle, runs through almost the entire length of the state and widens as it plunges into the plains of north Bengal at Sevoke Bazar, 20 km from Siliguri.
The river crosses Rajganj, Sadar and Mainaguri blocks of Jalpaiguri and Mekhliganj and Haldibari blocks of Cooch Behar.
