Tryon Creek is one of the major remaining free-flowing tributaries of the Lower Willamette River. About one-fifth of the watershed is parks and open space, including the Tryon Creek State Natural Area. Tryon Creek and its tributaries also run through several popular Portland parks, including Marshall Park, West Portland Park, and Maricara Park.
Environmental Services and many partners are working to improve the health of Tryon Creek and its watershed.
