Real-time Hydraulic Briefing
Synthesized water storage and flow dynamicsCurrent water storage for 水庫代碼 30801 is at —% with a water level elevation of 17.56 m.; inflow (4.3 m³/s) exceeds outflow (0 m³/s), resulting in net storage gain. Primary water supply covers Core districts of Greater Kaohsiung via Chengcing Lake Water Treatment Plant.
水庫代碼 30801 (ID: 30801) is an official Off-stream Reservoir situated in the Gaoping River System Diversion, operated and managed by Taiwan Water Corporation 7th District Management Office. In operation since 1960, this facility serves as a vital strategic pillar in Taiwan's regional water grid and flood mitigation network.
According to the latest observation, its effective water storage is approximately 235 (10k m³), with a storage ratio of —% and a real-time water level elevation of 17.56 meters. Hydraulic flow metrics record an inflow of 4.3 m³/s against an outflow of 0 m³/s (net flow: +4.3 m³/s), indicating active reservoir refilling. Catchment area recorded 241 mm of rainfall today.
Primary functional purposes include Metropolitan Drinking Water Buffer, Industrial Water Supply, Scenic Tourism, with key regional supply coverage extending across Core districts of Greater Kaohsiung via Chengcing Lake Water Treatment Plant.
