Valapattanam river is one of the major rivers in Kerala with its upper reaches lie in Coorg (Karnataka) at an elevation of 2,500 ft. above Mean Sea Level (MSL). The catchment area of the river up to the dam site in Kerala is 1,028 sq. km. Pazhassi Irrigation Project is the first major Scheme conceived for supplying irrigation water to Kannur district and was started in the year 1967. The head works were completed in 1979. Canal networks consisting main canal (46.26 km), branch canal (76.35 km) and distributaries (136.4 km) were also completed. Pazhassi Irrigation Project was included under the Command Area Development Programme (CADP) of the Ministry of Water Resources, Government of India during March 1999. The actual implementation of CAD activities started only in 2003. This project is included under restructured CADWM programme from 01-04-2004.
