The catchments area of Ankhu Khola is about 633 km2. The mean annual flow is estimated to be 58.38 cumecs. A design discharge of 34.5 cumecs having a probability of more than 40% has been considered.

Basic Characteristics

The Site of the project is located at 28000u201900u201d, to 28000u201957u201d, N in and 84054u201900u201d to 84055u201932u2033Eto 84055u201932u2033E latitude and longitude respectively. Proposed Intake structure has been impartially located at 70m downstream from existing Ankhu Khola Suspension Bridge. At Ringne bazaar,the power house has been proposed at right bank of the river at Sisneri khet. The proposed project shall generate average annual energy of 46.408 GWh. Transmission of the generated power will be connect through 12 km long KV transmission line to NEA Substation at Dhading Besi.
