Real-time Hydraulic Briefing

Synthesized water storage and flow dynamics

榮華壩 (Run-of-river Weir) is a major hydraulic facility managed under the Water Resources Agency. Primary water supply covers Yixing Hydroelectric Station & Shimen Reservoir catchment.

榮華壩 (ID: 10206) is an official Run-of-river Weir situated in the Dahan River, Tamsui River System, operated and managed by Northern Region Water Resources Branch, WRA. In operation since 1983, this facility serves as a vital strategic pillar in Taiwan's regional water grid and flood mitigation network.

Primary functional purposes include Yixing Hydroelectric Power, Upstream Sediment Interception, with key regional supply coverage extending across Yixing Hydroelectric Station & Shimen Reservoir catchment.
