In her letter, Mamata expressed her disapproval as majority of the water from the barrage goes to Bangladesh.
Calling it 'man-made conspiracy', Mamata urged the centre to stop it.
One day back, Mamata slammed centre over at the NCTC saying, "It is difficult for the state government to accept such arbitrary exercise of power by the Central government... which have a bearing on the rights and privilege of the states as enshrined in the Constitution of India."
"This has not been done in the instant case. The order, therefore, appears to be an infringement on the powers of state governments in matters of investigation and maintenance of order," she wrote in her letter.
According to the agreement signed between the two countries, Bangladesh should get only 35,000 cusecs during the dry season but it was getting 82,801 cusecs as the two gates were broken at the barrage.
The excess outflow of water from the barrage has reduced its water level of Bhagirati in India.
While Bhagirati should receive atleast 40,000 cusecs of water but it is receiving only 20,000 cusecs due to excess water drainage. No action has been taken yet for repairing the gates. Even the water level at
the barrage has reduced from 72 feet to 65.8 feet.
