Abstract: Xiaolangdi Reservoir, a crucial project for the control of water and sediment entering into the lower reaches, plays a very important strategic role in the management and development of the Yellow River. Since 1997, when the river is dammed, the amount of sedimentation in Xiaolangdi Reservoir reaches 3. 086 billion m3 until April 2016. The reservoir functions in the first stage of the later phase of sediment retaining. During the past 17 years since the impoundment of the reservoir in October 1999, it has played an important part in such aspects as flood control (ice prevention), sedimentation reduction, water supply, irrigation and power generation. The situation of flood control in the lower reaches of the Yellow River has improved effectively. The minimum bankfull discharge of the river channel increases from 1800m3/s before the flood season in 2002 to 4200m3/s before the flood season in 2016, which indicates remarkable benefits for the operation of the Reservoir
