This lake was named after the goddess Renuka. It is well connected by the road. Boating is available on the lake. A lion safari and a zoo are there at Renuka. It is the site of an annual fair held in November. It is designated as Ramsar site since November 2005. Renuka was the mother of parshuram ji
lake is an embodiment of Renukaji, the mother of Parshurama - one of the ten avatars of Lord Vishnu –and wife of the sage Jamadagini. As per the stories told by the locals, once an evil named Sahasarjuna killed the sage Jamadagini (Renuka ji's husband), and attempted to abduct his wife Renuka, but she threw herself in the lake to escape from him. Many gods and goddesses tried to bring Renuka out of the lake, but she decided to stay permanently in the river. After her death, Lake Renuka was formed.
Even today, the immorality of Goddess Renuka is celebrated. In the month of October or November (after Diwali) a fair is held on the bank of the lake. Saints from all parts of the country come to the lake to witness the holy assembly of mother and son. Huge procession to Parsu Ram tal is organized in which several idols of Parsu Ram, believed to be the incarnation of Lord Vishnu, along with other local deities, are carried in decorated palanquins. The idols are meant to be stationed at the temple but before that they are given a bath in the holy lake.
