The District Raitha Hitharakshana Samithi has decided to lay a siege to the Krishnarajasagar (KRS) dam on Thursday in protest against the order, said Samithi president G Madegowda.
Releasing water in the present situation would put the farmers of the district in a quandary, he said.
He said that a resolution should be passed at the ongoing session of the legislature in Belgaum against releasing water.
Farmers would keep vigil at the KRS reservoir to ensure that water is not released, Madegowda said and asked one person from each family to participate in the agitation near the reservoir.
Deputy Commissioner B N Krishnaiah has announced that schools and colleges in the district will remain closed on December 6 and 7 as a precautionary measure.
Prohibitory orders have been clamped within a radius of one kilometre of the KRS dam till December 10.
Entry of visitors to the Brindavan Gardens near Mysore has been banned till further orders.
