Where these numbers come from

Every figure on this page is recomputed in code from a public government feed, never typed by hand. The live elevation is a CDEC gage reading; feet below full pool, the operating-band gaps, the ~30-day change, and the meter conversion are all derived from that one validated reading and the published reference elevations. The reading is timestamped in the gauge above, and LakeLevelNow pulls the same feed the operator reports to.
