The Halali River is a tributary of the
Betwa River. It was formerly known as Thal River. In the 18th century,
Dost Mohammad Khan's forces killed a rival
Rajput force near Jagdishpur (later renamed to
Islamnagar) on the bank of the river. The river was renamed to "
Halali river" (the river of slaughter), because it appeared red with the blood of the victims. Another name for the river is Banganga. The Halali reservoir was commissioned in 1973. == References ==
