Outstanding Dams in Kerala
Kerala’s landscape is shaped by water. With 44 rivers and over 80 dams, the state has built one of India’s most extensive water management systems.
But dams in Kerala are not just about engineering. They are about survival, power generation, irrigation, flood control, and increasingly, tourism. Many of these dams sit deep inside forests, mountains, and valleys, turning them into some of the most scenic destinations in the state.
From Asia’s iconic arch dam in Idukki to the massive earth dam in Wayanad, these structures define Kerala’s relationship with nature.
Here are the most searched, well-known, and best dams in Kerala.
1. Idukki Dam
Idukki Dam is the most iconic and largest dam in Kerala. Built across the Periyar River, it is famous for its double curvature arch design, standing dramatically between two mountains, Kuravanmala and Kurathimala.
Completed in 1976, it is one of the highest arch dams in Asia and a major engineering achievement.
What makes Idukki unique is that it is part of a three-dam system, along with Cheruthoni and Kulamavu, forming a massive artificial lake. This reservoir powers the Moolamattom underground powerhouse, one of the largest hydroelectric stations in India.
Beyond its functional role, Idukki is a major tourist attraction. Surrounded by forests and wildlife sanctuaries, the dam offers breathtaking views, especially during monsoon when the reservoir fills up.
This is not just a dam. It is Kerala’s power engine and a symbol of modern engineering blending with raw nature.
2. Mullaperiyar Dam
Mullaperiyar Dam is one of the oldest and most historically significant dams in Kerala. Built in 1895 during British rule, it stands across the Periyar River and continues to function more than a century later.
What makes it unique is its interstate importance. The dam supplies water to Tamil Nadu for irrigation, making it a critical resource beyond Kerala.
Constructed using traditional masonry techniques, Mullaperiyar represents early engineering brilliance. Despite its age, it remains one of the most discussed dams in India due to safety and water-sharing debates.
The reservoir created by the dam forms the famous Periyar Lake, which is part of the Periyar Wildlife Sanctuary, one of Kerala’s top eco-tourism destinations.
Mullaperiyar is not just infrastructure. It is history, politics, and ecology all in one.
3. Banasura Sagar Dam
Banasura Sagar Dam is the largest earth dam in India and one of the most visually stunning dams in Kerala.
Located in Wayanad, it is surrounded by the Banasura Hills, creating a landscape filled with small islands that emerge when water levels drop.
Unlike concrete dams, this one is built using earth and rock, giving it a unique structure and appearance.
The dam plays a key role in irrigation and hydroelectric projects, but it is best known for tourism. Boating, trekking, and photography attract thousands of visitors every year.
Banasura is where engineering meets cinematic beauty.
4. Malampuzha Dam
Malampuzha Dam is one of the most popular tourist dams in Kerala.
Located in Palakkad, it creates the largest reservoir in the state and is surrounded by landscaped gardens, ropeways, and a famous musical fountain.
Built across the Bharathapuzha river system, it plays a major role in irrigation.
What sets Malampuzha apart is accessibility. Unlike remote dams, this one is designed as a recreational space, making it perfect for families.
It is often considered Kerala’s most tourist-friendly dam.
5. Mattupetty Dam
Mattupetty Dam, located near Munnar, is one of Kerala’s most scenic dams.
Built for hydroelectricity and water conservation, it is surrounded by tea plantations and rolling hills.
The calm reservoir reflects the surrounding mountains, making it a favorite for photography and boating.
It is also known for attracting wildlife like elephants and birds.
Mattupetty is less about scale and more about beauty.

The surrounding botanical garden and forest area make it a peaceful tourist spot.
Peechi is functional, simple, and essential.
8. Parambikulam Dam
Parambikulam Dam is located inside the Parambikulam Tiger Reserve, making it one of the most unique dams in Kerala.
It is part of a multi-reservoir system shared between Kerala and Tamil Nadu.
The dam supports irrigation and power generation while also preserving biodiversity.
Visitors often combine dam visits with wildlife safaris.
Parambikulam is where conservation meets infrastructure.
9. Thenmala Dam
Thenmala Dam is part of India’s first planned eco-tourism destination.
Located in Kollam district, it combines water management with sustainable tourism.
The area includes nature trails, adventure zones, and cultural programs.
Thenmala is not just a dam. It is a model for eco-tourism.
