Payippad Vallaarattu, or Jalotsavam, is a three day water festival conducted in Payippad Lake, 35 km from Alappuzha district of Kerala state in south India. There is a close relation between this Payippadu Vallam Kali and Subramanya Swamy Temple in Haripad.
The people of the Haripad village decided to build a Sree Ayyappan temple in accordance with a vision that they should install the idol of Subrahmanya, which they would find in the Kayamkulam River under a whirlpool. Finding the idol, the people brought back Subrahmanya vigraha in a boat, escorted by the devotees in other boats ceremoniously. In remembrance of this event a three day water festival is conducted each year.
