The Project aims to supplement the irrigation water supply to the existing Rinconada Integrated Irrigation System (RIIS). The RIIS has firmed-up service area of 7,208 hectares but around 2,000 hectares cannot be irrigated during both wet and dry seasons due to inadequate releases from Lake Buhi. The development scheme will include the construction of an impounding dam at Brgy. Bagumbayan. The proposed dam will have a structural height of 47.0 meters and storage capacity of 14.53 MCM at normal+E16 water surface level. This could irrigate 2,100 hectares during both wet and dry seasons.
