Gloryhole Spillway // Lake Berryessa, California 3D Model
The ‘Gloryhole’ Spillway is a large, vertical concrete tube that is used as overflow protection when the Lake Berryessa Reservoir reaches capacity. For the first time in 10 years, water in the Reservoir reached a high enough level to begin flowing into the tube, creating a ‘bathrub drain’ effect that has drawn visitors from all over Northern California and beyond!
