At one point the drone gets too close to the 'Glory Hole' and almost gets sucked in.
Lake Berryessa in California’s Napa County is a picturesque place. The Beautiful lake is held back by the Monticello Dam and is home to the famous 'Glory Hole'. Why the weird name you ask? Actually, the spillway resembles a morning glory flower, hence the name.
The Glory Hole is 72 feet wide and the water drops to a depth of 200 feet straight down. Since California is going through a drought, the spillway last saw some good action more than a decade ago. But some record rains in January and February this year has resulted in the lake reaching its maximum capacity.
