Ronghua Dam
dam in Taoyuan City, Taiwan

Ronghua Dam (Chinese: 榮華大壩; pinyin: Rónghuá Dàbà; Wade–Giles: Jung2-hua2 Ta4-pa4) is a concrete arch dam crossing the Dahan River, a tributary to the Tamsui River, in Fuxing District, Taoyuan City, Taiwan.
The dam was started in December 1978 and finished in June 1984. The cost was NT$1.83 billion.
The Ronghua Dam is within the catchment area of the Shihmen Reservoir, 27 kilometers upstream of the Shihmen Dam in the Dahan River gorge. The dam's main function is to prevent sand from moving downstream and building up as silt in the Shimen Reservoir. It also serves as a diversion point for sending water to a 40,000 kilowatt hydroelectric plant located 6 kilometres (3.7 mi) downstream.
As of 2012, the dam has no effective storage capacity, as almost its entire reservoir has been filled by sediment.

Why this record matters
The phrase “dam in Taoyuan City, Taiwan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Feb 15, 2025. The linked authority identifier is Q6312750. Authority coordinates are 24.737, 121.351. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1978, 1984 and 2012.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
