Kakki Dam is a concrete gravity dam built on the Kakki river, a tributary of the Pampa river in the Ranni forest in the Seethathodu panchayat of Pathanamthitta district in Kerala, India. The dam is located in a forested area adjacent to the Periyar National Park. It was built in 1966[1] as part of the Sabarigiri Hydroelectric Project. The water sources of the dam are from the Pampa dam and the Kakki river. The Sabarigiri project envisaged creation of two reservoirs which are Pamba and Kakki reservoirs and connecting these together to form a single source of water. The water from Pamba reservoir is connected to the Kakki reservoir through an underground tunnel of length 3.21 km. The intake of the Sabarigiri Powerhouse is from Kakki reservoir.[2] The dam is 336 metres (1,102 ft) long and 116 metres (381 ft) high and is located at an elevation of 981.45 metres (3,220.0 ft) above sea level. The release flows through Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally taluks [3] before emptying into the Vembanad lake.
