Buttermilk Falls is a waterfall in New Jersey. Height has not been officially recorded. Access details and conditions have not yet been verified in person by Fallspots — the data on this page comes from OpenStreetMap and USGS GNIS.
Middle Brook is a tributary of the Raritan River in Somerset County, New Jersey. The stream can be referred to as Rha-weigh-weiros, a Native American name meaning "running from a deep hole", on early maps of the area.
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.
