Lake Berryessa is the seventh largest man-made lake in California, located in the gorgeous Napa Valley wine country. It is held back by the 304 foot tall Monticello Dam, home to the famous “Glory Hole” spillway that sits just yards away from the concrete edge of the dam.
The funnel shaped spillway resembles a morning glory flower, but has not been seen in action since droughts have prevailed in the region for over ten years.
At the opening and widest point, the amazing hole measures 72 feet across before narrowing down to approximately 28 feet as it drops straight down two-hundred vertical feet. Once it reaches the bottom it bends ninety degrees and then straightens out before eventually draining out on the other side of the dam into Putah Creek, according to Sun-Gazing.com.
When January and February brought record amounts of rain to the region and raised the lake’s water capacity to near maximum levels, the sudden influx of so much water in such a short span of time meant that the glory hole was finally back in action. On February 16, 2017 the edge of it was officially runneth over.
Check out this awesome drone footage to see what it looks like when thousands of cubic feet of water per second rush down the hole.
Watching the video is visually hypnotic and gives the feeling of actually falling into the hole’s vast depths – much like a ride at an amusement park. Wait until the drone enters the hole to feel the magnetic pull. Truly unbelievable!
