Tryon Creek
Videos
Tryon Creek is a 4.85-mile (7.81 km) tributary of the Willamette River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about 6.5 square miles (16.8 km2) in Multnomah and Clackamas counties. The stream flows southeast from the Tualatin Mountains through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area to the Willamette in the city of Lake Oswego. Parks and open spaces cover about 21 percent of the watershed, while single-family homes dominate most of the remainder. The largest of the parks is the state natural area, which straddles the border between the two cities and counties.

Fanno Creek, nearly hidden by foliage, meets the much larger Tualatin River near a pedestrian bridge.
Fanno Farmhouse was the home of Augustus Fanno, for whom the creek is named. Built in 1859 and restored by the Tualatin Hills Park and Recreation District, it was added to the National Register of Historic Places in 1984.
WES trains use the former Oregon Electric line along lower Fanno Creek between Durham and Beaverton.
