Pyuthan borders Dang Deukhuri District to the southwest along the crest of the Mahabharat Range and extends about 50 km northeast through the Middle Hills to a 3,000+ meter ridge that is both Pyuthan's border with Baglung district of Dhaulagiri Zone and the main watershed between the (west) Rapti and Gandaki River basins. Pyuthan borders Rolpa district to the west. Of the two upper tributaries of the West Rapti River, Pyuthan contains all of Jhimruk Khola and the lower part of Madi Khola after it exits Rolpa. The Madi-Jhimruk confluence is in southern Pyuthan, in the Mahabharat Range. On the southeast Pyuthan borders Lumbini Zone including Arghakhanchi and Gulmi districts. The valley of Jhimruk Khola is the core of Pyuthan district. Its alluvial plain is intensively planted in rice during the summer monsoon. Wheat is grown as the winter crop. Madi Khola has eroded an inner gorge and is less suited to traditional irrigated agriculture.
