CC Madhya 9.197
kṛtamālāya snāna kari āilā durvaśana
After thus assuring the brāhmaṇa, Śrī Caitanya Mahāprabhu proceeded further into southern India and finally arrived at Durvaśana, where He bathed in the river Kṛtamālā.
Presently the Kṛtamālā River is known as the river Bhāgāi or Vaigai. This river has three tributaries, named Surulī, Varāha-nadī and Baṭṭilla-guṇḍu. The river Kṛtamālā is also mentioned in Śrīmad-Bhāgavatam (11.5.39) by the sage Karabhājana.
