The river originates at the Thamsar Glacier in the Dhauladhar range of the Himalayas, flows through the Uhl valley crossing the villages Bada Gran (Baragram) and Barot.

The Lumba Dugh also originates in the East of the Dhauladhar Range and flows past Luhardi village before meeting the Uhl.

This water is then diverted to the Shanan Power House, Jogindernagar using a tunnel and penstocks, where it runs turbines for electricity generation.

The vision of the hydel project scheme was to construct five power stations using the same water that is drawn from the Uhl river.

Of late, with the introduction of trout in the Indian Himalayan region, fish farms have come up on the banks of Uhl at Barot.
