On 17 September 2001, Typhoon NARI caused severe damage. Due to hung peak inflow in the upstream watershed area of Dahushanzhuang st.,the downstream rain water sewers could not drain in time, which lead to flooding, threatened the residents 'lives and caused property loss.In order to improve the flood problem and prevent massive mud flowing into rain watersewer system,Taipei City Government constructed the ecological and flood control of Dagoi Stream at the end of Dahushanzhuang st. which can detain flood and intercept sediment, also preserve natural ecology of Dago Stream and water activities.
The land acquisition of the park was executed with the support of the landlords and residents.Undertaken by Hydraulic Engineering Office of Public Works Department of Taipei City Government, project costed 140 million dollars,with a regulating capacity of 131,500 cubic meters. In regular time,the area is a ecological park,which can reduce peak flow as much as during Typhoon NARI 44.6%, and the pool began operations in May 2008.This is one of the favorite places for Taipei residents.
大溝溪生態治水園區
民國90年9月17日因納莉颱風肆虐大湖山莊街一帶上游集水區發生驟大尖峰入流量，且下游雨水下水道未能時宣洩而發生水患，造成居民生命財產受損。臺北市政府近年以「上游保水、中游減洪、下游防洪」的理念推動總合治水計畫。為改善山洪水患問題並止大量泥沙流入雨水下水道系統，於大湖山莊街底興建大溝溪生態治水園區，滯延大湖山莊街一帶上游集水區洪水及攔截泥沙，並維持原有大溝溪自然生態及親水功能。
大溝溪生態治水園區之空間規劃將自然景觀與防洪工程融為一體之佈置，為減緩對生態及景觀之衝擊，保留原大溝溪河道，營造人工濕地生態池等親水空間，使防洪工程融入自然景觀形成和諧之美，並可於平時提供市民一遊憩休閒去處，汛期時可有效降低洪峰流量，發揮防洪效能。除此之外，大溝溪生態治水園區連結多處登山步道，儼然成為適合全家大小「一日遊」的休憩旅遊帶，是台北市民假日休閒的最佳選擇之一。
