The Lohore Khola HEP is a proposed reservoir storage project situated on the Lohore Khola, a tributary of the Karnali River in Dailekh District. The project is located a few kilometers downstream from the confluence with Chham River and upstream of Dungeshowr. The catchment area of the Lohore River at the reservoir site is . Based on the isohyetal map of the Karnali River Basin, average annual rainfall for the basin is estimated to be . As there is no stream gauge on the Lohore River, its flow was estimated using data from Station 240 (1963–2000) located on the Karnali River at Asaraghat with a catchment area of . The sediment flow into the river is estimated to be 2.4 million tonnes per year. As the economic internal rate of return (EIRR) for the project is highest for the draft rate of 0.7, the flow for power generation was estimated for this draft rate. The riparian flow was assumed to be 10 percent of the monthly minimum flow; i.e., .
