Historic Lake Levels

Storage data for Lake Almanor is initially determined by PG&E from a PG&E gauge located near Prattville.   This storage data is then transmitted to the California Department of Water Resources (DWR) and posted daily on the DWR website.  PG&E/DWR data is preliminary and subject to later revision by the U. S. Geological Survey (USGS).


USGS daily storage data for Lake Almanor is published annually as USGS gage 11399000 "Lake Almanor at Prattville, CA".  USGS Lake Almanor storage data is available from 1913 but much is not available online.  Some of the early data is monthly storages.
