What this level means
The level comes from CDEC - California Data Exchange Center (DWR). When the pool drops, shoreline beaches grow and shallow ramps can run out of concrete.
How this reading is taken
CDEC - California Data Exchange Center (DWR) measures the water surface and publishes the value continuously. This page stores the latest reading at build time and refreshes the record daily, so the figure above is a real measurement rather than a model or an estimate.
No operating agency publishes a full pool elevation for Lake Berryessa that we can cite, so this page shows the reading and its trend without a percentage.
Elevations are given in feet above the gauge datum used by the operating agency. Two lakes are only comparable with each other through how full they are, not through their raw elevation, because each dam sits at a different height.
