Tl’el Tāna means ‘the lake that sits below the flint hill’ and refers to the mountain to the west which was the only source of tool flint for the Äshèyi people. The lake has small mbeda (rainbow trout), which people catch with nets and hooks.

To the south of Tl’el Tāna modern maps show Giltana Lake which reflects an effort to use the Southern Tutchone name, Tl’el Tāna, albeit for the wrong lake.
