Namal Lake (Urdu: نمل جھیل) is a man-made lake located near Rikhi, a village on one corner of the Namal valley in Mianwali District, Punjab, Pakistan.

In 1913, British engineers built a dam on Namal lake to address the scarcity of irrigation and drinking water for Mianwali city.

[6] But with the passage of time, construction of the Thal Canal and the installation of tube wells, squeezed up its utility of water up to some limit.

The hill torrents and rains fill the Namal Lake round the year.

The tail of the canal was at Mianwali, where it conveyed water to lands in the Civil Station.
