Noting that present laws "create more disputes because of several loose ends" in the existing Acts, Shettar said that the Inter State Water Disputes Act should be revisited.
"None of the present laws are able to establish a just water regime to the satisfaction of all the stakeholders," he said.
Without referring to the3 Cauvery water sharing dispute between Karnataka and Tamil Nadu, Shettar said in some cases the Indian government stand has delayed the projects, which can be otherwise.
"The absence of a water regime had been forcing us to go to the Supreme Court, by which the Government of India is trying to absolve its conciliatory role which is prescribed by the Indian Constitution, which is an expected role being the head of the federal structure, which needs to be strongly established," he said.
Shettar said he made this statement because Karnataka as a "mid and upper riparian state suffered in both utilisation and construction of projects, which resulted in depriving the people of Karnataka their due and legal right of their share of water."
