Upper Foss River Falls is a waterfall in Washington. It drops roughly 337 feet. Access details and conditions have not yet been verified in person by Fallspots — the data on this page comes from OpenStreetMap and USGS GNIS.
Foss River Falls is a 650-foot (200 m) drop on the West Fork Foss River in the Alpine Lakes Wilderness Area, King County, Washington. Its sources are at Delta Lake, and the 70-foot (21 m)-wide drop flows year-round. The waterfall is split into two parts. Each part is split into several tiers.
Is the water flowing right now?
Most waterfall sites don't tell you this. The waterfall itself is almost never gauged, but a USGS streamgage in the same watershed can tell you whether snowmelt has started, peaked, or run dry.
