Kiul River
The Kiul River is a tributary of the Ganges. It originates in Giridih in the state of Jharkhand and flows through Lakhisarai, Sheikhpura and Jamui districts of the state of Bihar and joins the Harohar river in the Diara region.
Course
The Kiul originates from the Tisri Hill Range in the Kharagdiha police station area of Giridih district. After forming the boundary of the district for a short distance it enters Jamui district through a narrow gorge near the Satpahari hill. It first flows in an easterly direction close to the southern base of the Girdheswari Hills. It turns northward at their eastern extremity and passes near the town of Jamui. Two miles south of Jamui it is joined by the Barnar, below this point it receives the Alai, a mountain stream, and near Jamui railway station it is joined by the Anjan. It then flows northeast up to Lakhisarai, passes below the railway bridge between Kiul junction and Lakhisari station, and is joined a few miles north of that place, near Rahuaghat, by the Harohar, a continuation of the Sakri River. After this it turns due east and falls into the Ganges near Surajgarha. Until it meets the Harohar the Kiul has broad sandy beds and in some places is as much as half a mile wide, though it contains very little water in summer.In the course of its run the river traverses a total length of and drains an area of.
