Located on the outskirts of Sibsagar Town, Joysagar Lake is considered to be the largest manmade lake within the Indian sub-continent. Listed amongst the top 17 prime tourist attractions in the state of Assam, this lake was created by King Rudra Singha, a famous Ahom ruler of the 17th century. Spread over a sprawling 318 acre area, this magnificent water body is named in memory of the king's mother, Queen Joymati, who according to the folklore was tortured to death in the nearby region of Jerenga Pothar. The site of this water-tank was chosen where Siulikpha convicted Queen Joymati in order to extract information regarding her exiled husband Gadapani, who was subsequently later crowned as the king. When her son Rudra Singha later ascended the throne, he dedicated this water body in the cherished memory of his mother and named 'Joysagar'.
