The lake was made during the reign of the renowned Ahom king,
Rudra Singha. About 5 km from the Sivasagar township, three set of temples are located on the northern bank of the lake. The most renowned among these sanctuaries is the
Joy dol, which is also known as the
Keshavnaryan Vishu dol. As the name suggests, the sanctuary is devoted to Lord Vishnu and his numerous manifestations. This lake was formed in 1697, in just 45 days, in the memory of
Joymoti Konwari, mother of Rudra Singha. The lake covers an area of 318 acres (1.28 square km). The water level of the lake is 14 feet higher from ground level. == Tourism ==
