Name

In Mizo language, the word Ṭam is a contraction of anṭam, which means a mustard plant; and Dil means "lake".

Origin and etymology

The origin and etymology of Ṭam Dil are shrouded in myth. Folklore has it that a married couple had a jhum plot in this small valley surrounded by small steep hills. The man unfortunately died leaving the wife to care for the crops alone. In the middle of the field was a robust mustard plant, conspicuously bigger than any other plants. One night the widow has a visitation by her husband, who informed her to take special care of the giant mustard plant as it was a harbinger of immense blessing. On the wake, she did as told, and the plant thrived very well.
As time went, the widow remarried but the new husband objected to any thing reminiscence of the deceased husband, and so he plucked the plant up by the roots and discarded it. The vast hole left in the ground was then soon filled by water to become an exquisite lake. Hence the name of Ṭam Dil, for the "lake of the mustard".

Fauna

Biodiversity scientists started faunal exploration in the early 2000s. A new species of frog called Ṭam Dil leaf litter frog was discovered in 2007 from this lake and described in 2010. A rare species of Assam Kukri snake, Oligodon catenatus was discovered in 2020. In 2024, a new species of snake, Smithophis mizoramensis was discovered.

Tourism

The lake is reconstructed as part of building a fishing reservoir by the Fisheries Department, Government of Mizoram. In an attempt to promote and develop the destination, lake-side resorts are maintained by the Tourism Department in partnership with ZX Eden offering boating, kayaking and other adventure activities for kids and adults.
