Neyyar Dam, Gravity dam in Kerala, India

Neyyar Dam is a rubble masonry gravity dam on the Neyyar River in Thiruvananthapuram district, Kerala, at the foot of the Western Ghats. It is 56 m high and 295 m long, with a structural volume of 105,000 m3, and its reservoir holds 106,200,000 m3. Its sloped downstream face is built of grey stone blocks, and a roadway with a pale balustrade and lamp posts runs along the crest.

Work on the Neyyar irrigation project began in October 1956 under the Kerala government, and the dam was completed in 1958. It was built on land given by the agriculturist and landlord Karuvachi Krishnan Panicker of Maruthummootil, Kallikkad, and one of the contractors was Jagathy Chellappan of Jagathy, Thiruvananthapuram.

The Sivananda Yoga Vedanta Dhanwanthari Ashram near the dam teaches yoga and meditation in the natural setting of the Western Ghats, drawing seekers to practice traditional methods surrounded by forest and water.

Buses from Thiruvananthapuram's Thampanoor stand reach Kattakkada, from where services to Neyyar Dam run about every half hour. The nearest railway station is Thiruvananthapuram, roughly 32 km away, and the airport 38 km. A crocodile farm, deer park, watch tower and lake garden sit near the dam; the lion safari park is closed because the lions stopped breeding.

A Crocodile Rehabilitation and Research Centre at the dam site maintains a protected environment for crocodiles and otters. This facility offers an unexpected opportunity to observe these animals up close and learn about local wildlife conservation efforts.
