Facility Overview: The Shangping Weir is located on the Shangping River, a main tributary of the Touqian River. It draws water from the Shangping River to supply irrigation water to the Zhudong Canal irrigation area, and primarily diverts water to the Baoshan Reservoir and Baoshan Second Reservoir for water storage and regulation. It is the most important public water source for the Hsinchu area.
The Shangping Weir is a concrete, inverted, basket-shaped fixed weir. The intake is located upstream of the sediment discharge channel on the left bank of the weir. It has four intake channels: Intake Channel 1 is dedicated to supplying water for agriculture in the Zhudong Canal and for the Baoshan Reservoir; Intake Channels 2-4 supply water to the Baoshan Second Reservoir.
