A bench headed by Chief Justice Dipak Misra said it will consider the suggestions given by all stakeholders while finalising the Cauvery scheme.
"We will pronounce the order tomorrow. If that is not possible, then we will pass the order on May 22 or 23," the bench, also comprising Justices AM Khanwilkar and DY Chandrachud, said.
Senior advocate Shyam Divan, appearing for the Karnataka government, today submitted suggestions to be dealt while finalising the Cauvery scheme.
Mr Divan said that Cauvery Water Dispute Tribunal (CWDT) had provided for minimum water to be allowed to remain in the reservoir on behalf of Tamil Nadu and Karnataka to maintain a steady flow of water, adding that, the draft scheme does not deal with this aspect.
Attorney General KK Venugopal, appearing for the centre, told the court that the centre has modified the provision of the scheme that had empowered it to pass directions from time to time with regard to water distribution.
The top court, in its verdict delivered on February 16, had asked the Centre to frame the Cauvery management scheme, which also included creating the Cauvery Managament Board, within six weeks for release of water from Karnataka to Tamil Nadu, Kerala and Puducherry.
The scheme, once finalised, would deal with the issue of water share of the four states in different circumstances like normal and deficient water years in the Cauvery river basin.
The top court had modified the Cauvery Water Disputes Tribunal (CWDT) award of 2007 and made it clear that it will not be extending time for this on any ground.
It had raised the 270 tmc ft share of Cauvery water for Karnataka by 14.75 tmc ft and reduced Tamil Nadu's share, while compensating it by allowing extraction of 10 tmc ft groundwater from the river basin, saying the issue of drinking water has to be placed on a "higher pedestal".
