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.
