Siran and Kunhar are well known rivers of the district. The Siran issues from Panjool and flows through the western plain of Pakhli. Two canals have been taken out from the Siran river, the upper Siran canal at Dharial and lower Siran canal at Shinkiari. From Pakhli the Siran runs into the Tanawal hills and joins the Indus at Tarbela in the north west. Its total course is between 70 to 80 miles, and it irrigates 6,273 acres of land. The Kunhar bursts out the from the Lulusar at the head of Kaghan valley and after a turbulent course of 110 miles falls in the river Jhelum at Pattan. Since the land upon its bank is little level therefore, its water is not used for irrigation purposes. Some other notable bourn and nallas which flow in district Mansehra are Pootkatha (Mansehra), Nadi Unhar (Shergarh), Butkus (joins the Siran near Icharian), Ichar and a small Siran stream that flows in Batagram and joins the river Indus near Thakot.
