During the "Tamil Nadu Bandh", shops will remain shut till 6 pm in the state.
The Stalin-led party said it would hold continuous protests like the one today at Valluvar Kottam here, till the CMB was constituted.
With the DMK and its allies calling for a shutdown over the issue in Chennai and Coimbatore on April 5, the protests over Cauvery may take epic proportions, similar to what Tamil Nadu witnessed a year ago during jallikattu and farmer suicide agitations.
In Delhi, AIADMK Members of Parliament staged a protest outside Parliament. "Will also take out Cauvery rights retrieval walk from the delta area", Stalin said at a press conference on Sunday.
Nearly on the same lines, the BJP state leaders were taking on the DMK accusing the Dravidian party of double standards for protesting seeking CMB on one hand and aligning with the Congress, whose government in Karnataka was opposed to it. BJP national secretary H Raja had even said that Tamil Nadu would get its share of water if the BJP wins the Karnataka election.
Tamil Nadu has been pushed to hold protest demonstrations and agitations seeking to implement the order of the top court on the Cauvery issue due to the "collective negligence of the central and state governments", a resolution adopted at the meeting said.
The main opposition party, Dravida Munnetra Kazhagam's (DMK), has also called for a strike on April 5.
The apex court though had reduced the Tamil Nadu's share of Cauvery water, it had allowed it to extract 10 tmcft groundwater from the river basin to tackle its pressing need for the drinking water.
Tamil Nadu, in its contempt plea, said the Centre was bound to give effect to the judgement by framing a scheme so that the authorities of - Cauvery Management Board and Cauvery Water Regulation Committee - were put in place within six weeks.
Both the Centre and the Tamil Nadu government had on 31 March moved the Supreme Court on the issue of constitution and composition of the CMB in compliance with its 16 February on water allocation among riparian states.
Rival DMK has demanded that Chief Minister Palaniswami convene a meeting of his cabinet and pass a resolution condemning the Centre and Prime Minister Narendra Modi over the Cauvery issue.
