Real-time Hydraulic Briefing
Synthesized water storage and flow dynamicsCurrent water storage for 德基水庫 is at 97.8% with a water level elevation of 1,407.06 m. Storage is up 0.6% compared to yesterday at the same time; inflow (26.8 m³/s) exceeds outflow (1 m³/s), resulting in net storage gain. Primary water supply covers Greater Taichung and downstream cascade hydroelectric stations.
德基水庫 (ID: 20201) is an official On-stream Reservoir situated in the Dajia River System, operated and managed by Taiwan Power Company. In operation since 1974, 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 17,762.9 (10k m³), with a storage ratio of 97.8% and a real-time water level elevation of 1,407.06 meters. Hydraulic flow metrics record an inflow of 26.8 m³/s against an outflow of 1 m³/s (net flow: +25.81 m³/s), indicating active reservoir refilling.
Primary functional purposes include Dajia River Cascade Hydropower, Greater Taichung Municipal & Agricultural Water, Flood Control, with key regional supply coverage extending across Greater Taichung and downstream cascade hydroelectric stations.
