WATCH: Oregon lake drains down large mystery hole each spring, but where does it go?

BEND, Oregon -- An incredible phenomenon is playing out in Central Oregon right now, as it does this time most years.

A mountain lake, filled each fall and winter, is literally draining down a large hole as if it is a bath tub.

The Bend Bulletin shared video of the incredible phenomenon on YouTube in late April. That video has now been seen more than 1-million times.



As reporter Scott Hammers explains Lost Lake is just off U.S. Highway 20 near Hoodoo Ski Area.


Hammers reports that over the years people have tried to plug the tube and stop the drainage. Forest Service officials say they’ve recovered car parts, engines and other debris in the hole. But McHugh tells the Bulletin that if anyone ever did plug the hole it would probably result in significant flooding along the nearby road.

As for where the water goes, officials tell the Bulletin they don't know for sure.
