Heading south from the estuary, there is a marsh habitat created by the SoW. Previously there was nothing here except some grass fields, but the SoW opened channels to bring in tidal water and dug several ponds, and now it has become home and / or restaurant to many forms of life. On the mudflats next to the ponds, at low tide thousands of fiddler crabs come out to strut their stuff.
從河口往南，有片荒野保護協會營造出的沼澤棲地，這裡原本是一片單調草地，由於縣府在附近開闢微風運河，破壞了原本的環境，荒野爭取到這片土地後改做棲地營造，開闢水道引進潮水，又挖出有幾口水塘，經多年演替，已經成為多種生物的餐廳和家園。
