The Ghataprabha Reservoir has storage of about 659 million cubic meters, providing irrigation to a total extent of 1,396,000 hectares of land, inclusive of the area under stage I. The third stage of the project includes raising the Full Reservoir Level of to 662.94 meters. This would create gross storage of 1.448 billion cubic meters, channelised into a 202 km-long right bank canal and the 86 km-long Chickkodi Branch Canal. This would irrigate 191,386 hectares of land and bring the total area under the project to 3,310,000 hectares.
