The Ulhas River is one of the most important rivers in Maharashtra, India. Flowing through the scenic regions of the Western Ghats and the bustling Mumbai Metropolitan Region, the Ulhas River plays a crucial role in providing water, supporting biodiversity, and sustaining urban and rural life.

Ulhas River Origin

The Ulhas River originates in the Western Ghats near Khandala, in the Raigad district of Maharashtra. The river begins its journey from the north of Lonavala hills, gathering water from several small streams and mountain springs. The origin of the Ulhas River is surrounded by lush green valleys and steep hill slopes, making it a beautiful sight during the monsoon season.

From its origin, the river descends rapidly, carving through the rocky terrain and forming picturesque valleys before flowing into the plains.

Ulhas River Route and Course

The Ulhas River route covers a distance of approximately 122 kilometers (76 miles). After originating from the Western Ghats, it flows northwards through Karjat and Ulhasnagar, then turns westwards, passing through Kalyan, Thane, and Mira-Bhayandar before emptying into the Thane Creek and Vasai Creek, eventually merging with the Arabian Sea.

Along its route, the Ulhas River forms several distributaries and creeks, which are vital for irrigation, drinking water supply, and local ecosystems. The Ulhas River map shows how it winds through the heart of the Mumbai metropolitan region, serving as a major water source for cities like Thane, Kalyan-Dombivli, and Navi Mumbai.

Ulhas River Length

The Ulhas River length is around 122 kilometers, making it a medium-sized river compared to other major rivers of Maharashtra. Despite its moderate length, the river’s basin supports millions of people and contributes significantly to the regional economy through agriculture, fishing, and urban water supply.

Ulhas River History

The history of the Ulhas River dates back to ancient times. The river has supported human settlement for centuries, providing fertile plains for agriculture and easy access to water. Historical towns like Kalyan and Thane developed along its banks and became prominent trading ports during the Maratha and British eras.

During the colonial period, the river was also used for inland navigation and transport of goods between the coastal areas and the interior regions. Today, while the Ulhas River continues to serve domestic and industrial needs, it also faces challenges from urbanization and pollution concerns that are being addressed through various conservation initiatives.
