Dam Big Glory Hole
Derek Miller found this super-cool alternative dam just above Napa Valley. Well, he didn’t actually find it, but he read about it somewhere, and we’re all better for it. The Monticello Dam has a peculiar feature, hilariously named the ‘glory hole’:
Monticello Dam holds back Putah Creek to form Lake Berryessa. Rather than having a spillway to the side as some dams do, Monticello has a glory hole set behind the dam into which water will spill rather than rise to a height where it would flow over the dam. Water from Lake Berryessa is discharged from the dam into the beginning of Putah Creek.
Nifty. Derek even thinks he’s found a satellite view from Google Maps, though you can’t see the hole.

Erm… Yeah you can see the Glory Hole!
It’s next to the dam – no water running through it at the time of this pic though.
