Koosah Falls sits in Linn County, Oregon. It drops along McKenzie River. The base sits at roughly 2,795 feet of elevation. Drive time is about 24 minutes from Black Butte Ranch. A trail — Waterfalls Loop Trail #3503 — runs within 20 meters of the marked location. This is one of the more frequently visited falls in the state by our popularity model. Source records come from OpenStreetMap and USGS GNIS.

Koosah Falls, also known as Middle Falls, is the second of the three major waterfalls on the McKenzie River in the heart of the Willamette National Forest in Linn County, in the U.S. state of Oregon. The waterfall is notable for its main drop of 64 feet (20 m) that plunges into a considerable pool, south of Santiam Pass. Koosah Falls is located 0.5 miles (0.80 km) downstream south of Sahalie Falls, southeast of Salem, Oregon, northeast of Eugene, Oregon and west of Mt. Washington. The word koosah means "sky" in Chinook Jargon.

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.
