Dago Creek Ecological Water Management Park Introduction
Located at the southern end of Dahushan Villa Street in Neihu District, Dagou Creek is a naturally-formed stream that flows down from Mount Baishi Lake, with an elevation of 485 meters. The upper section of the creek is mostly bordered by secondary forests, while the lower section, after passing through the Yuanjue Waterfall, flows into the residential drainage system, eventually merging into Dahushan Park via the box culvert under Dahushan Villa Street. The entire watershed spans approximately 3,500 meters with a catchment area of 340 hectares. To ensure safety and conservation, the restoration of Dagou Creek in Neihu District employs a porous near-natural construction method, providing habitats for flora and fauna. This has led to a rich ecological resource, as indicated by surveys conducted by the Geotechnical Engineering Office, which have recorded species such as the Taiwan Blue Magpie, the Microhylid Frog, the Chinese Tree Frog, the Taiwan Black-spotted Butterfly, the Endo Purple Butterfly, the Jewel Butterfly, the Rhacophorus arboreus, the Little Egret, the Five-color Bird, and the Yellow-spotted Cricket, making it an excellent outdoor ecological classroom. Previously an agricultural area, the lower regions of Dagou Creek have undergone urban development, with land readjustment transforming the area into a residential community. Due to road demands, the creek has been converted into a box culvert, which has historically struggled to handle torrential rain, leading to erosion and landslides. Significant damage even occurred during Typhoon Winnie in August of 1997. The upper reaches of Dagou Creek within the Dahushan Villa community have been restored using stone protection along the banks, providing porous spaces conducive to wildlife habitation while reducing erosion. Additionally, to accommodate recreational and leisure needs, a waterside pathway has been constructed along the creek bed, serving as a backyard for local residents. To create a natural ecological environment, the restoration includes fish ladders and solid bed structures to minimize elevation changes in the creek bed, slow down flow rates, and reduce erosion energy. The shallow water areas also help to maintain aquatic habitats for fish, shrimp, and aquatic plants. Moreover, facilities such as waterside platforms and pathways have been installed in wider sections of the creek to allow residents and visiting tourists to enjoy interaction with the water.
