Ghataprabha Project Canals-This project involves three stages leading to the construction of dams across the Ghataprabha river at Dhupdal and Hidkal, 114 krri long canal along the east side, 197 km long canal along the west side and creation of irrigation facilities for 3.18 lakh hectares of agricultural land in Belgaum and Bijapur districts.
