Lake Creek (Siuslaw River) Lake Creek (Siuslaw River) Lake Creek is a major tributary of the Siuslaw River in Lane County in the U.S. state of Oregon. On average, the long creek contributes about a third of the lower Siuslaw's water volume. Beginning near Prairie Mountain near the Lane–Benton county border in the Central Oregon Coast Range, Lake Creek flows generally southeast through the Siuslaw National Forest to the vicinity of Horton, then southwest through the communities of Blachly, Triangle Lake, Greenleaf, and Deadwood. It enters the Siuslaw River at Swisshome, by water from the larger stream's mouth on the Pacific Ocean at Florence.
