Notes and references

Notes

1. The "height" listed is the vertical distance from the crest of the dam to the original stream bed at the downstream toe of the dam — hydraulic height, not foundation height.
2. Clear Lake is a natural lake. The dam adds only 315,000 acre-feet (389,000,000 m³) of capacity and controls only the top 7 feet (2.1 m) of the lake.
3. Donner Lake is a natural lake. The dam adds only 10,300 acre-feet (12,700,000 m³) of capacity and controls only the top 10 feet (3.0 m) of the lake.
4. Lake Tahoe is a natural lake with a volume of 120 million acre-feet (150 km³). The dam controls only the top 6 feet (1.8 m) of the lake.
5. The lake is only partially in California, as it sits astride the border between California and Nevada.
