A holy place on the banks of the Saraswati. Balarama is said to have visited this place.

Gautama had three sons – Ekata, Dwita, Trita. He was happy with their pious lifestyle. Once he conducted a yajna and went to heaven. The kings and priests present at the yajna  then considered Trita as the chief priest. Ekata and Dwita were not too pleased with this. By the end of the yajna, they had amassed a large number of cows. They took the cows east, with Trita leading the way. Ekata and Dwita conspired behind his back and led the cows in another direction. Trita was oblivious to this and kept walking. Near the banks of the Saraswati he saw a wolf and while escaping from it, fell into an empty well. He used the creepers in the well, chanted mantras and conducted a yajna there. The chants began resonating in devaloka, and Brihaspati along with the devas reached there. They asked Trita what boon he desired and he said he only wanted to be rescued from the well. Immediately the Saraswati river flooded the well and Trita rode on its waves and got out of the well. On reaching home, he cursed Ekata and Dwita and turned them into wolves, and further that their offspring would be cattle, monkeys and other animals.

The place where the devas appeared before Trita later became known as Udapanatheertha as per Mahabharata Shalyaparva Chapter 36.
