CC Madhya 18.71
‘kālīya-hrade’ snāna kailā āra praskandana
The next day, Śrī Caitanya Mahāprabhu went to Vṛndāvana and took His bath at Kālīya Lake and Praskandana.
Kālīya-hrada is mentioned in the Bhakti-ratnākara (Fifth Wave):
kālīya-tīrtha-sthāne bahu-kārya-siddhi haya
“When one takes a bath in Kālīya-hrada, he is freed from all sinful reactions. One can also be successful in business by bathing in Kālīya-hrada.”
