8 Kms from Jowai on National highway - 44 is a man made lake at Thadlaskein fed by a Perennial spring. According to tradition, one Chieftain Sajar Nangli had an irreconcilable difference with the King of Jaintiapur. Not wanting to be blamed for an inevitable bloodbath he decided to flee from the Kingdom with his followers. Before his departure, however, they dug the present day lake with the ends of bows as a memorial. The lake is revered by the people of Raid Mukhla who continue to offer sacrifices near the Lake. It is also a popular picnic spot for locals.
