Ulhas River

The Ulhas River is an important west flowing river in Western India in the state of Maharashtra draining an area 4,637 km² in size.

Origin

The Ulhas River originates in a valley north of the Rajmachi hills formed by mountain streams draining the northern slope of those hills which are part of the Sahyadri range of the Western Ghats in the Raigad district of Maharashtra.

Course

From the point of origin the river flows north turning left where it is joined by River Salpe,its right-bank tributary. It then begins its north-eastward journey and passes the Anglo-Eastern Maritime Academy which is situated on its right bank at Khandpe village. The river bypasses the Palasdhari village where it receives the discharge from the Palasdhari Dam starting a northward course beyond this point coming to lie parallel to the rail tracks only to be distracted by the town of Karjat. Meandering through Karjat, it reaches further north synapsing with River Peg between Bhivpuri Road and Neral. Continuing its run along Neral it is joined by River Poshir,another right-bank tributary at Nikhop village. It flows north skirting Badlapur where it receives the run-off from Chikoli Dam. Near Raw water pump house of MIDC Jambhul the river meets Barvi Dam discharge water also called as Barvi River. The confluence is a tourist and fishing hub for villagers around. The river flows through Ulhasnagar to which it gives its name.It then passes under the rail bridge connecting Ambivali and Shahad and shortly after confluences with its biggest tributary formed by merging of River Bhatsa and River Kalu which together account for 55.7% of the total catchment area of River Ulhas.
