Lake Berryessa ‘Glory Hole’ Continues To Drain (PHOTO)

The heavy rainfall occurring in means the iconic “Glory Hole” is flowing again.

That’s not a typo either.

According to reports, record rainfall scattered across the state in 2016, helping to fill Lake Berryessa almost to the brim, KRON-TV reports. This event marks the first time in nearly a decade that water has flown into the lake’s unique spillway at the Monticello Dam.

Commonly called the “Glory Hole” by residents and tourists in the area, the spillway is officially called the “Monticello Dam Morning Glory Spillway.”


“The fact that the lake is finally going to fill up again is special,” Dianna Englebrecht told the Mercury News. “The power, the energy of it, it’s something you don’t see every day.”

The hole functions similar to a drain in a sink or tub — it just sits at the top of the lake instead of the bottom.

When the lake’s water levels rose, it began to overflow at the top of the pipe connecting to the river, which spans 8-foot-wide and 200-foot-long, and ran at a rate of 48,400 cubic feet of water per second.

The lake and dam are a source of water and electricity for California’s North Bay area.
