雙溪水庫(以下簡稱本水庫)規劃於新北市雙溪區丁子蘭溪與其主流雙溪之匯流口南方約800公尺處(詳圖1)興建拱壩，經環評範疇界定會議確認可行之替代方案及應進行環境影響評估之項目後，於本(104)年度開始辦理「台灣地區北部區域雙溪水庫可行性規劃檢討(5)-環境、生態專題-第二階段環境影響評估」作業。 由於水庫下游承受水體位處自來水水質水量保護區，就集水區污染源、污染物屬性，應依環境影響評估河川水質評估模式技術規範第五條規定，採用規範認可之BASINS/HSPF模式辦理水質評估。該項評估作業需藉由水質測站資料蒐集、集水區土地利用調查分析、水質採樣與檢驗，配合數值程式參數律定，來完成集水區水質模式建置。 另前期(103年度)規劃土資場、施工營區(管理中心)及施工道路部分，經座談會及初步訪談地主由於產權複雜且部分因祖祠公廳將被徵收而強烈反對。現行方案仍存在用地取得之不確定因素，有必要增加補充調查規劃研擬其他可行替選方案。 為提供「第二階段環境影響評估」之調查與評估作業研析，爰提出『台灣地區北部區域雙溪水庫可行性規劃檢討(5)-環境、生態專題-水質模式建置與補充調查規劃』，爰研提工作計畫書。

Shuangxi Reservoir is located at Ding Zhi Lan River in Shuangxi District, New Taipei City. It is considered an important water resource infrastructure by the government. The receiving water body downstream of the reservoir belongs to Shuangxi Running Water Water Quality and Quantity Protection Area. We follow the BASINS/HSPF model approved by Article 5 of Technical Guideline on Environmental Impact Assessment for River Water Quality. The early stage construction planning review concludes that there are rich ecological resources in the landfills and construction camp areas, and the construction activities can directly have an impact on the water quality of Shuangxi River. Hence, to minimize the environmental impact of the reservoir construction, it is necessary to add supplementary survey planning, and to formulate alternatives.
