Before the construction of the Tehri Dam, the town of Old Tehri was a bustling administrative and cultural hub. It was located at the confluence of the Bhagirathi and Bhilangna rivers, with roots tracing back to the 9th century. However, due to the Tehri Dam project, Old Tehri was completely submerged in the early 2000s, displacing thousands of families. Although lost beneath the waters, its legacy lives on in the memories of its people and in the modern township built above it. Visitors often express a sense of awe knowing a whole city lies beneath the lake’s calm surface.

The Tehri Dam is not just India’s tallest dam but also one of the tallest in the world. At 260.5 meters high, it was designed to harness the mighty Bhagirathi River. The project faced strong opposition over environmental and seismic safety concerns, but it was finally completed in the early 21st century. The dam today generates over 1,000 MW of hydroelectric power and provides irrigation and drinking water to several northern Indian states. For tourists, the sight of this colossal structure nestled between the hills is both humbling and fascinating.

Tehri Lake, the reservoir formed by the dam, is now a major attraction in Uttarakhand. The lake stretches across dozens of kilometers and has become a hotspot for water adventure. Jet skiing, kayaking, banana boat rides, speed boating, water zorbing, and paragliding are some of the popular activities available. With the pristine Garhwal Himalayas as a backdrop, the lake offers a unique combination of thrill and natural beauty. Annual adventure festivals further boost its appeal, drawing tourists and adrenaline junkies from all across India.

New Tehri was built as a rehabilitation site for the displaced population of Old Tehri. Spread across the steep slopes, it now stands as a well-planned township that blends modern amenities with panoramic views. Homestays, small cafés, and markets cater to both tourists and locals. The town is also a base for treks and spiritual journeys. With less commercial chaos than other hill stations, New Tehri offers a peaceful and refreshing alternative for travelers looking to explore Garhwal's authenticity.

Among the key landmarks in New Tehri is the iconic Clock Tower. Located at the town center, it symbolizes resilience and modern identity. Built after the displacement, the Clock Tower serves as a reminder of the old town’s lost heritage and the spirit of renewal that now defines New Tehri. It's a popular photography spot and often features in tourist itineraries. As you walk around it, you’ll often hear stories from locals about their journey from Old Tehri to this new elevated life.
