By percentage, Folsom Lake is California’s most imperiled reservoir. State data show it’s at just 35% capacity. That puts it a shade below Lake Oroville, the reservoir seen in the first slide that’s just 36% full.

The comparison above shows an entirely new peninsula emerging on the reservoir in 2021. The image also shows the toll the drought is taking on plant life. The vegetation seen in the open spaces of the Sacramento suburbs to the west and the Sierra foothills to the east are notably browner in 2021 compared to 2020. That’s bad news for wildfire season, which has already gotten an early start in California.
