Hamm Creek Estuary is located just south of South Park along the Duwamish River and is one of the two only salmon spawning creeks in the Duwamish River. Today, the native vegetation here provides food for juvenile salmonids, in the form of bugs living on the plants as ready themselves for their journey to the Puget Sound. Surrounded by urbanization, Hamm Creek is a pocket of natural estuarine habitat. Hamm Creek is a legacy site where the first effort to recognize that the Duwamish Waterway was a river that needed saving from the industrial uses of the past by John Beal. John started this effort as one person volunteering his time and efforts, growing it into not only a local but a national concern and effort to improve the health of the river.
