The dam was started in 1961 under the Kallada Irrigation and Tree Crop development project with an original cost of Rs. 13.28 crores. The revised estimate of Rs. 728 crores at the 1999 schedule of rates made the cost escalation to be reported at 5,356 per cent. The ayacut targeted was 61630 hectares (net) and 92800 hectares (gross). Though the project was targeted for completion, and priority in allocation was given during Ninth Plan, it could not be completed and commissioned fully.
