There are a few telltale signs it's been an especially rainy winter in Northern California. Often there are mudslides (check), tons of snow in the Sierra (yup, got that), and then there's the Glory Hole. That benchmark was also passed Tuesday morning.

The Glory Hole is Lake Berryessa's unconventional spillway. When the North Bay gets lots of rain, the Napa County reservoir fills and water starts to spill into the hole. It operates similar to a bathtub drain, but, in this case, the drain isn't at the bottom of the tub. Instead, it's located near the top.
