This Timelapse of Shasta Lake in Northern California compares water levels in late June 2020 to a recent image in late May 2021. Surface elevation of the reservoir — formed by the impounding of the Sacramento River — was at 1,016 feet (309.6 m) in the first image and was already down to 959 feet (292.3 m) at an earlier stage in the summer this year. This difference of 57 feet (17.4 m) equates to a volume loss of more than 1.1 million acre feet, or 359 billion gallons — enough water to fill an Olympic swimming pool 550,000 times. Currently, about 95% of California is experiencing a severe drought as rising temperatures dwindle snowpack and reservoirs across the state see record-low inflows.
