Brief about Project
The Malampuzha Irrigation Project in Palakkad district (Kerala) is the first large-scale irrigation system attempted in Kerala state. The project consists of a dam constructed across the river Malampuzha, a tributary of Bharathapuzha. It consists of network of canal system to irrigate an area of 22.554 Th ha. The dam is straight gravity type of masonry with an earthen saddle. The length of masonry portion 1626.71 m and the earthen portion is 222.20 m. The capacity of the reservoir is 226 MCM at Full Reservoir Level (FRLFull Reservoir Level) +115.06 m and a water spread area of 22 Sq.km. The maximum height of the masonry dam is 38.10 m. The CCA of the project is 22554 hectare and annual irrigation is 45108 hectare. The project has two main canal, left and right bank.
i. The left bank is designed for dischage at head of 21.24 cumec to serve 17050 hectare and the length is 31.60 km. The canal with its network empties its residual water into Gayathri river to be used by Cheramangalam scheme about 5 km downstream of the river. The scheme was complted in the year 1951 and irrigates an ayacut of 1205 hectare.
ii. The right bank canal has a length of 32 km irrigating an area of 4299 hectare. the head dischage is 4.05 cumec.
The Malampuzha reservoir provides drinking water for Palakkad Municipality and 6 adjacent panchayaths. The Malampuzha garden set up in the downstream of the dam having an area of 28.5 acres, is the biggest tourist attraction of Kerala. There is also fish culture in the reservoir run by the Fisheries Department.
