Kandy Lake (Sinhala: නුවර වැව), also known as Kiri Muhuda or the Sea of Milk, is an artificial lake in the heart of the hill city of Kandy, Sri Lanka, was built in 1807 by King Sri Wickrama Rajasinghe next to the Temple of the Tooth.

The king first built a dam across the paddy fields, starting from the Paththirippuwa (octagon) side, where the steps leading into the lake by the Mahamaluwa (Esplanade) are still visible, stretching across to the Poya-maluwa.

One such is that the small island at its centre was used by the king's harem for bathing and was connected to the palace by a secret tunnel.

The parapet wall, giving the appearance of a cloud, is popularly called Walakulu Bemma and measures 633.82 meters.

Sri Wickrama Rajasinghe built a dam for the purpose of reaching the opposite side of the lake.

Sri Wickrama Rajasinghe was unable to complete the wall before the city was captured by the British and he was forced to relinquish the Kandian kingdom.

There are a number of bird species found on the lake, including Indian cormorant, white egret crane, wood stork and pelican.

The government and the surrounding schools are trying to decrease the problem by putting up signs and operating environmental societies.
