Green Lake Falls is a waterfall in Washington. It drops roughly 981 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.

Green Lake Falls is a large, very difficult to access waterfall located a short distance below the outlet of remote Green Lake, in North Cascades National Park, Whatcom County, Washington. It is 979 feet (298 m) high & averages 150 feet (46 m) wide and flows year-round. It has several tiers, including a 300-foot slide and a 500-foot plunge.

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.
