高屏溪攔河堰
💡 Why is storage ratio N/A? Answer: Gaoping Weir is a run-of-river diversion weir without deep storage capacity. It routes river flow directly into municipal treatment plants, so storage percentage is not applicable.

Real-time Hydraulic Briefing
Synthesized water storage and flow dynamicsCurrent water level for 高屏溪攔河堰 is at 16.55 m.; inflow (91.1 m³/s) exceeds outflow (85.1 m³/s), resulting in net storage gain. Primary water supply covers Greater Kaohsiung (supplying Pingding, Kaotan, and Chengcing Lake water treatment plants).
高屏溪攔河堰 (ID: 30901) is an official Run-of-river Weir situated in the Mainstream Gaoping River System, operated and managed by Southern Region Water Resources Branch, WRA. In operation since 1999, this facility serves as a vital strategic pillar in Taiwan's regional water grid and flood mitigation network.
Current real-time water level elevation stands at 16.55 meters. Hydraulic flow metrics record an inflow of 91.1 m³/s against an outflow of 85.1 m³/s (net flow: +6.02 m³/s), indicating active reservoir refilling.
Primary functional purposes include Greater Kaohsiung Municipal Water Supply, Industrial Water Supply, with key regional supply coverage extending across Greater Kaohsiung (supplying Pingding, Kaotan, and Chengcing Lake water treatment plants).
