Salal Dam is located on the Chenab River in Jammu and Kashmir. This dam is crucial for generating hydroelectric power and regulating water flow for agricultural needs.

Bansagar Dam is located on the Son River, and it provides both irrigation and hydroelectricity to the states of Madhya Pradesh, Uttar Pradesh, and Bihar.
